"How do you
get a $16500 tonearm for $1900? Let me suggest that you compare the Pete Riggle Woody(tm) with the Durand Telos. "
"I could never afford to
purchase a Schroeder, and The Woody is every bit as good. Every parameter
you could want is easily adjustable; and it's so beautiful, and so musical too."
- Ted Danowski
Universal TM Tonearms
Universal Tonearms TM are exceptionally musical. They provide a full array of adjustability, adaptability,
and convenience features never before offered. They can be optimized to work with any standard mount cartridge.
(If a Woody tonearm is needed for use with SME style interchangeable headshells, for example the Ortofon SPU cartridges,
check out the Woody SPU tonearm: http://www.vtaf.com/id102.html )
Compare the Woody
Universal Tonearm (tm) at $1900 to the Schroeder and Reed tonearms in the $4000 to $7500 range, and the
Durand arms priced at $8500 and $16,500. Dream no more. The Woody tonearms are extremely musical, and anticipate
all user needs at a price many audiophiles can afford.
In addition to exceptional sonics, the Woody(tm) tonearms provide easy setup, and remarkable ease of adjustment. With
the record in play it is easy to adjust VTA, azimuth, and anti-skating force. All adjustments are made with thumbscrews.
Hex wrenches (Allen wrenches) are not required.
Woody Universal Tonearms allow
the user to change headshells and headshell adjuster plates, and to change counterweight mass, to optimally perform
with the specified, compliance, mass, and tracking force of any cartridge. Headshells and headshell adjuster
plates in brass, aluminum, and wood (different masses) are provided with the Woody tonearm. Multiple counterweights and counterweight
boosters are provided to balance the weight of any cartridge and its preferred headshell and headshell adjuster plate.
A setup guide is provided in the Owner's Manual covering the setup for a wide range of cartridges.
Universal Tonearms are the most easily adjustable and most easily adaptable (to any
standard mount cartridge) tonearm product ever offered. Owners invariably comment on the musicality of Woody tonearms.
Attention has been paid in the design of Woody
Universal Tonearms to every detail affecting sound quality, ease of adjustment, adaptability to various cartridges, and
ease of setup and use. Nothing has been overlooked. Examples: Extensive use of wood and brass, the StringTheoryTM string
bearing, oil damping, high quality Teflon insulated phono wire, Cardas cartridge clips, and excellent RCA connectors
all contribute to a more musical experience. Installation of cartridges on the Woody tonearm is easier and more risk
free than for any other tonearm. The ergonomic finger lift makes hand cueing easier and more secure than for other
tonearms. The continuous wire run eliminates intermediate electrical connections, for better sound.
Standard effective lengths for Woody Universal TonearmsTM are
229 mm (9 inches, SME length), 240 mm (9.45 inches, Rega length), 254 mm (10 inches) and 310 mm (12.2 inches). We have also
provided arms in the effective lengths of 356 mm (14 inches), and 406 mm (16 inches).

John Hoffman's review in
Positive Feedback Online:
Beneath that beautiful French polished wood lies a remarkable
bit of creative thinking in regards to the obstacles presented by analog playback and neatly executed engineering solutions.
If you value a hand crafted product and the passion and integrity of a designer, then I would suggest you give the String
Theory arm serious consideration."
"The defining characteristic of the String Theory arm is its combination
of proper tonal color and its unflappable expression of micro dynamics that make up music. What this translates to is this:
music has a robust and fleshed out tonal balance, yet the fine detail which makes it realistic is not lost in the pleasing
texture of the music."
Thad Aerts review, Part 1, in hifizine
"For being a rather sophisticated design, the Woody was a snap to set-up
and the whole process (alignment included) took me a little over an hour. Again, I already had the VTAF installed (which makes
a big difference in terms of time) and I made periodic minor tweaks as I listened to music. Still, Riggle is to be applauded
for the thought that he put into the arm’s design – not to mention its stunning aesthetics ."
Thad Aerts review, Part 2, in hifizine
Thad compares the Woody to his modified Rega RB250, which uses Incongnito wire, the Pete Riggle VTAF, and
the Pete Riggle Counterweight for the Common Man, all of which are dramatic improvements to the RB250:
best analogy I can muster to describe the differences I heard between the two tonearms was that the Rega (greatly
improved by modifications) was like watching a really high quality tubed television. Then, take the same program material
you just viewed and watch it on a state of the art plasma or LCD or whatever. There is really no contest. The Woody brought
more air to whatever it played while also raising the level of definition. There were many times while listening where I wondered
how much better it could really get short of better equipment downstream. It is, hands down, the best tonearm I’ve
ever had the pleasure of hearing. Throw in its stellar good looks and ridiculous ease of set-up and you have a clear

By interchanging headshells
and headshell adjuster plates of different material densisties, and counterweights to provide the correct balance, the
Woody tonearm can be set up for the optimum 8 Hz resonance frequency with most cartridges. The laws of
physics dictate that the higher effective mass associated with lower resonance frequency provides reduced headshell
vibration from stylus oscillation, giving improved clarity, inner detail, nuance, air and bass response. This
is true across the entire audible spectrum. The chosen resonant frequency (8 Hz) is sufficiently high to avoid problems with
footfall vibrations and record warps.
headshell and long headshell leads allows easy cartridge installation (user not required to stand
on head) in conjunction with continuous tonearm wire.
Easily adapts to shallow, medium, or high platters.
adjustments are easily made using knurled nuts or thumbscrews. Allen wrenches (hex wrenches) and

Accessories Provided with the Woody Universal Tonearm:
Provided accessories include: Detailed
owners’ manual specific to the parameters of each String Theory Woody tonearm, mounting distance gage, alignment gage,
overhang gage, high viscosity oil for damping cup, syringe for transferring high viscosity oil, and additional headshells,
headshell adjuster plates, and counterweights to allow the user to set up to optimally play any cartridge with standard
The Woody arms
are modeled by computer, and subsequently tested, to verify that each will balance and provide the intended
tracking force with the intended cartridge(s) and will have correct effective mass to achieve the desired resonant frequency.The
tonearm wand has a square cross section which tapers from the pivot to the headshell. While it is common in the industry
to design tonearms for a resonant frequency somewhere around 12 Hz, theory dictates (and we believe on the basis of experience)
that more massive arms, with a resonant frequency closer to 8 Hz, sound better. This is because across
the audible frequency spectrum, arms with lower resonant frequency respond less to needle talk vibrations than arms with
higher resonant frequency. Tracking problems with record warps and footfalls do not usually occur with a tonearm
resonant frequency of 8 Hz and above.
With low compliance cartridges (roughly 5 to 8 compliance units) the Woody
will typically use a brass headshell and headshell adjuster plate. With medium compliance cartridges (roughly 10 to
16 compliance units) the Woody will typically use an aluminum headshell and headshell adjuster plate. With high compliance
cartridges (roughly 18 to 30 compliance units) the Woody will typically use a Spanish Cedar headshell and headshell
adjuster plate. The $1900 USD price includes all three headshells and headshell adjuster plates, as well as
multiple counterweights to set up for optimal playback with all cartridges.
|Bearing System with VTAF, AZOF, ASOF,Height Adjustable Lift/Lower, and Counterweight Adjuster
At this point we have extensive experience with Woody tonearms ranging in length from 9 to 16 inches. These
tonearms are all very musical. We have provided users with a number of Woody tonearms in various lengths
and for various cartridges. We are getting glowing reports.
VTA on the Fly (VTAF): These tonearms use the proven VTAF (Vertical Tracking
angle on the Fly) system, allowing the VTA to be dialed in to the sweetest angle while the record is in play
as the user listens to the effect of VTA. The VTAF also isolates the tonearm system from the armboard. Many VTAF users
have attested to the remarkable sonic benefits of isolation provided by the VTAF. With the VTAF, a thin adjuster
wheel running on fine threads moves the tonearm pedestal up or down to change VTA. The VTAF Teflon Upgrade, which lines the
bearing surfaces of the VTAF with Teflon, and improves sonics and smoothness of operation, is standard with the Woody tonearms.
Azimuth On the Fly (AZOF): Also
incorporated into the Woody tonearms is a system which allows the azimuth to be to be dialed in to the sweetest condition
while the record is in play, as the user listens to the effect of azimuth. AZOF is achieved by a manually adjusted lever
on the lower platform which controls the position of a vertical axis snubber pin directly under the tonearm pivot. The vertical
axis snubber pin loosely engages a small aluminum channel secured under the tonearm wand, with the channel axis parallel to
the tonearm axis. Once the preferred azimuth has been dialed in, it is desirable in theory, but actually unnecessary in practice,
to adjust the lateral balance of the arm to achieve a balance such that the snubber pin is not in continuous contact with
Anti-Skate On the Fly (ASOF): Anti-skate is set using a blank
record or blank space in a lead-out groove. With the record turning the user rotates the anti-skate knob at the
center of the top plate. This puts a twist into the bearing string, creating an outward skating tendency to balance the
inward skating tendency caused by stylus drag. Anti-skate is properly set when the stylus tends to stay put or move slowly
outward when placed on a blank space on the surface of the record. For purchasers who wish, we can provide the Pete Riggle
Anti-skate Measurement System (PRAMS) free of charge.

The arm for each customer is modeled by computer, and subsequently
tested, to verify that the arm will balance and provide the intended tracking force with the intended cartridge(s)
and will have correct effective mass to achieve the desired resonant frequency.The tonearm wand has a square cross section
which tapers from the pivot to the headshell. While it is common in the industry to design tonearms for an arm/cartridge
resonant frequency somewhere around 12 Hz, theory dictates (and we believe on the basis of experience) that more massive
arms, with a resonant frequency closer to 8 Hz, sound better. This is because across the audible
frequency spectrum, arms with lower resonant frequency respond less to needle talk vibrations than arms with higher
resonant frequency. Tracking problems with record warps and footfalls do not usually occur with a tonearm resonant
frequency of 8 Hz and above.
The design philosophy is to use wood
wherever possible, and brass and Delrin ™ where wood is not as practical as desired. Where necessary for reduced
tonearm effective mass, aluminum or wood can be used for headshell components. This philosophy has resulted a
remarkably balanced tonal character which makes real music. The question might arise "My Rega arm with
the VTAF and the CCM sounds wonderful. Can the Woody tonearms actually sound better?" The answer is that while the Rega
arms with the VTAF and CCM are truly excellent, the Woody arms are more musical.
The Woody design uses a uniquely configured
string unipivot suspension with snubbing to make tonearm handling the same as with conventional bearings. Tonearm
handling is made more convenient with the use of a long, light, wood, ergonomically shaped finger lift. A
precision lift/lower device is standard. The tonearm rest/lock uses a strong magnet to attract a steel target under the tonearm
wand. The tonearm is held down securely against vertical forces, but lifts nicely off the magnet when put into play by
The uniquely configured string unipivot
is stiff in the horizontal plane, resulting in excellent bass response. The string unipivot bearing is suspended
from a knurled brass knob at the center of the upper platform. Anti-skate tendency can be adjusted by rotating this knob.
The knob is locked with a thumbscrew when in the correct position.
All Woody tonearm adjustments are easy
to make without reliance on hex keys. We object to the common use of hex keys and special tools for tonearm adjustment.
Hex keys are so easy to misplace, and once misplaced, it is a nuisance to find the right size. VTA is adjusted with
the VTAF. AZimuth On the Fly is adjusted with the AZOF lever. Tonearm lateral balance is adjusted with knurled brass
balance weights. The Counterweight for the Common Man provides tracking force adjustment with a knurled thumbscrew to lock
the counterweight in place. The headshell provides easy alignment using only one knurled nut. Anti-skate
tendency is dialed in by rotating a knurled brass knob on the upper platform, allowing Anti-Skate On the Fly (ASOF). Even
the lift/lower device is easily adjusted upward and downward, using a knurled thumb-screw to lock the device in place.
For arms with adjustable VTA this is an important feature. The Woody is probably the most easily adjusted tonearm
|The Pleasure of Vinyl Playback with the Woody
A tiny circular bubble level is
made integral with the headshell adjuster plate. This tiny bubble level provides the user with a quick visual
determination of azimuth and VTA. A lateral balancer is provided to get perfect lateral balance at the desired azimuth
once azimuth has been dialed in by the AZOF system.
The standard wiring configuration provides
a continuous run of 36 gage Teflon insulated, silver plated, stranded copper wire between the cartridge and the
phono stage. We've tried a number of wire products. So far this is the best we've found. The wire harness
is shielded by a small diameter thin walled brass tube along the length of the tonearm, unshielded at the compliance loop
(similar to VPI tonearms), and shielded with foil and a drain wire from the compliance loop to the RCA plugs. The shield is
not connected at the RCA plugs or at the cartridge. A long ground wire connects the wiring harness shield system
to the chassis ground at the phono amplifier. A short ground wire is provided in the event the user needs to connect the turntable
to the grounding system (this is important for tables with metal motor boards, such as the Thorens TD124, The Garrard 301,
or the Lenco tables). Configurations allowing user selected RCA patch cables are optional. The Woody is designed
for ease of wiring and rewiring (not that rewiring will ever be required). The extreme flexibility of the wire used
minimizes changes in anti-skate force as the arm sweeps across the record.
In our listening room we are using
a 12 inch Woody with a Denon DL103 cartridge, and are getting very musical results. The 12 inch
nominal Woody has a length of 310 mm (12.2 inches) from stylus to pivot, with an overhang of 13.1 mm (.516 inches) for the
Baerwald alignment. This particular arm was set up with an effective mass of about 30 grams, to which one must add the cartridge
mass to get the total mass. Cartridge mounting is standard with screws spaced 0.5 inches on centers. This arm sounds
wonderfully musical with the DL103, and may sound even better with some of the more sophisticated cartridge products.
For higher compliance cartridges the
arm effective mass can be lowered, still keeping the resonant frequency around 8 Hz, by using aluminum or Spanish
Cedar for the headshell, the headshell adjuster plate, or both.
Woody tonearms are available in lengths
to allow easy replacement of older arm designs. Typical arms in the 9 to 10 inch range vary from a length of 229
mm to 254 mm. Woody arms are available to replace arms of any length. We have had great success with 12, 14, and 16

French polish, rubbed on in many sessions. French polish is legendary for bringing out the beauty of wood.
There is nothing like it. Lacquered Brass finish is used for brass parts, with an optional Smokey Silver finish ($120 U.S.
extra). At present the wood being used for most Woody tonearms is aged Spanish cedar, which looks and finishes like various
species of mahogany, but is lower in density.
Interest in this family of tonearms
is running quite high. The list price is $1900 USD. We suggest comparing the Woody arms to Schroeder
