Welcome to the Revolution

Hi there, welcome to my blog - La Revolution Deux. It's an odd name - but I like it! Here you will find all the info on my various DIY Guitar effects builds, amplifiers and guitars. Everything from a humble Ibanez tubescreamer to the holiest KLON Overdrive.

You may also find a few effects builds that I am looking to move on - usually in exchange for other effects/gear/cash. You can always check my ebay account to see what I've got up for grabs.

Have fun, enjoy the blog - Fred Briggs :-)

Pigtronix - Philosophers Tone Compressor (Germanium Gold)


I love compressors. I love them more than any other guitar effect - and there's a reason; they are the glue that sticks a great performance together. Unless you're Jimi Hendrix or Eric Clapton a compressor *will* improve your tone and help you sit in a band mix much better.

The Pigtronix Philosophers Tone has been making waves for a while now and I thought it was time to get it placed up on the blog.

Here's the description from the Pigtronix website regarding the regular version of the Philosophers Tone;

"The Pigtronix Philosopher’s Tone is a state-of-the-art analog compressor / sustainer, providing endless clean sustain. With variable Sustain, Blend and Treble controls, the Philosopher’s Tone offers a huge range of compression sounds for the discerning musician. The Philosopher’s Tone also contains a harmonic distortion for clean or dirty compression sounds and any mixture of the two. While the Philosopher’s Tone rocks on its own, it is designed to play well with other dirt pedals in order to create your ultimate distortion tone that sustains forever.

Pigtronix Philosopher’s Tone is unlike the common compressor. This pedal has more sustain and less noise. The dynamic range, touch sensitivity, overall transparency and outright sustain of the Philosopher’s Tone is un-paralleled in the crowded world of compressor pedals.

Practitioners of the mystical and ancient art of alchemy long sought an element called the Philosopher’s Stone, believing that, if found, it could turn lead into gold and bestow immortality upon the man who wielded it. For such a tiny pedal to create so much sustain, this device represents a musical equivalent to this mythical substance in the world of guitar pedals."


And to get an idea of how the Philosophers Tone sounds here's the ProGuitarShop demo video for you;



Now, onto the guts of this thing. Thanks for these photos goes to jwpartain1 of the freestompboxes.org forum;



From these gutshots and the attached information Mystic Whiskey managed to draw up a schematic and verify a build against an original Philosophers Tone Gold Germanium. Here's the scheme for you;


Let's have a look at a few of the different sections - the "Grit" control blends in either a clipped or clean version of the compressed signal. The "Blend" control blends between the unaffected signal and the compressed/clipped signal. The "Treble" control is nothing special and is set up as a simple treble cut. It's a decent design and really works for a nice overdriven yet compressed tone.

For those of you brave enough to take it on - here's a vero layout for the Philosophers Tone Gold;
