Pigtronix<br />
philosopher’s tone<br />
stompbox compressor<br />
Iam a compressor junkie. <strong>The</strong>re are<br />
very few pedal compressors I do not<br />
own, fewer I have never owned, and<br />
still fewer I have never tried. This baby<br />
from the wonderful Pigtronix company<br />
is my newest favorite.<br />
While most compressors are capable<br />
of getting that country “cluck” tone or<br />
the “jazz squash,” they usually suffer<br />
from two things: noise and tone suck.<br />
By its very nature, compression will<br />
bring up any extraneous noise from your<br />
guitar or cords, or anything in front of<br />
them. That’s why most players put them<br />
early in their signal chain. But some of the<br />
common designs, such as the MXR<br />
DynaComp Ross, and their ilk suffer from<br />
self generated noise, too. Given that we<br />
all hate hiss, why would you want a pedal<br />
that makes more noise than it has to?<br />
Another problem with most pedal<br />
comps is the inability to mix the squashed<br />
tone with the original signal, which is a<br />
very useful thing to do in many instances,<br />
as it will increase your sustain and still<br />
allow the natural transients to spike through.<br />
I especially like to do this with acoustic<br />
guitar or 12-string.<br />
Still another problem is the way most<br />
compressors dull your tone. Not so bad<br />
when you are using a Tele, Strat, or other<br />
single-coil pickup guitar. But try to run<br />
a humbucker like a Les Paul thru most<br />
squashers and you really can mud up<br />
your tone, when all you want is some<br />
more sustain. This can happen at even<br />
mild settings,<br />
<strong>The</strong> Pigtronix Philosopher’s Tone<br />
addresses each of these issues. It is the<br />
size of the standard jem/MXR box, but it<br />
has five knobs: Grit, sustain, blend, treble<br />
boost, and output level. <strong>The</strong> housing features<br />
a studly true-bypass mechanical<br />
footswitch, and a very bright blue LED<br />
indicator shines real purty when you<br />
switch it on. One niggle: you must use an<br />
external power source, as this baby runs<br />
on 12-18 volts DC (with center negative,<br />
thankfully). Not really a problem, since it<br />
comes with a nice 15V “1-Spot”-looking<br />
switching supply wall wart, with a decent<br />
long power cord. <strong>The</strong> extra voltage really<br />
lets this pedal perform better than other<br />
compressors, but if you lose the included<br />
supply, it might be difficult to find a<br />
replacement in East Overshoe, New<br />
Mexico, so be forewarned.<br />
<strong>The</strong> standard controls of output level<br />
and compression/sustain amount are familiar,<br />
and even with the sustain set to zero,<br />
this baby can pummel an input of a lowgain<br />
amp nicely when the output is dimed.<br />
<strong>The</strong> blend control works beautifully<br />
from no added compression at fully counter-clockwise,<br />
to no uncompressed signal at<br />

fully clockwise settings. In between, there<br />
are many mixtures that will suit myriad<br />
tone scenarios. Like I mentioned, I really<br />
liked the 50/50 blend when I ran my<br />
Fishman Rare Earth acoustic pickup into<br />
it, and also less-compressor blends will<br />
give you good sustain when placed before<br />
some dirt source such as a fuzz box, without<br />
taking away all of your punch. This<br />
unit is great in front of my ZVex Wooley<br />
Mammoth (a really nasty low sustain fuzz)<br />
or my vintage Dan Armstrong Green<br />
Ringer. <strong>The</strong> low noise of the Pigtronix box<br />
is most appreciated in this situation.<br />
<strong>The</strong> treble boost control<br />
is the best part of this box.<br />
It adds a sweetly-musical<br />
high-end boost that sounds<br />
great on humbuckers. And<br />
if you like really maximum-sparkly<br />
single-coil<br />
clean tones, maxing this<br />
control with a Strat or Tele<br />
is just the ticket. Damn<br />
fine chime! Voiced perfectly,<br />
the treble is never<br />
harsh or spikey, just shimmering.<br />
Boffo!<br />
Also included is a simple<br />
“grit” control, which<br />
can dial in a mild diodetype<br />
distortion. Even at the<br />
highest settings, its not a<br />
raging stack tone, nor a<br />
fuzzface style buzz.<br />
Actually, the dirt reminds<br />
me of that which one can<br />
get by using the distortion<br />
control on a Roland JC-<br />
120. Not a natural tubelike<br />
response, but it can be<br />
useful in situations where<br />
you want a glassy fizz (with the treble<br />
boosted), or a subtle patina (treble turned<br />
down) that follows the attack, blooming<br />
as as the note sustains. Personally, I could<br />
do without this feature, but I know some<br />
folks will dig it.<br />
Did I mention this thing is quiet?<br />
Damn, I don’t know how they do it, but<br />
this is by far the quietest stompbox squash<br />
that I have encountered. Some unique circuit<br />
design must be the reason, and the<br />
underside of the unit warns, “Warranty<br />
void if opened.” I’m sure that is just more<br />
enticement for some cloners to open this<br />
baby up to see what’s going on inside, and<br />
Pigtronix explains on their website that<br />
the Philosopher’s Tone is unlike most<br />
other compressors in that it is NOT based<br />
on a CA3080 chip. I don’t really care, I<br />
just love the sound. In the past 10 years,<br />
the Pigtronix Philosopher’s Tone is not<br />
based on a CA3080 chip.<br />
This baby beats my Demeter<br />
Compulator, and my Analog Man<br />
BiCompRosser, so it is now a permanent<br />
part of my stage arsenal. Those other two<br />
are damn fine units, but more expensive<br />
than the Philosopher’s Tone. Not common<br />
on the local store scene, but it is easily<br />
available online for usually around 170<br />
bucks, versus 220 for the Demeter and 3<br />
bills for the BIComprossor. I have seen<br />
Pigtronix stuff at Twin Town Guitars, and<br />
if you check around, I am sure some other<br />
places have it —just don’t expect to find<br />
it at Guitar Center or Best Buy.<br />
In a comparison to this unit, the<br />
Demeter is more subtle, and the<br />
BiComprossor is capable of obscene<br />
squash and the Trey Anastasio-type compression<br />
sound (he runs two Ross Units in<br />
series-- hello noise floor!). But the<br />
Pigtronix is by far the most versatile, lowest<br />
noise unit, with very fine build-quality,<br />
and includes a power adapter. It’s small<br />
size and bright blue LED indicator are<br />
perfect for crowded pedalboards. Plus it is<br />
cheaper than the others. What more could<br />
you want?<br />
