I just picked up a Philosophers Tone compressor that seems broken.
It has constant fuzz noise even with the grit turned right down and a huge drop in volume.
I was wondering if it's possible to bypass the grit section

Re: Damaged Philosophers Tone
is it the baby one or an older one?
If the small one I doubt it will be an easy job but possible.
If the older one then maybe

Thanks for your replies.
It’s the bigger original one.
I’ve tried different voltages from a multi power supply including the 18v.
I’ll see if i can get a dedicated 18V plug to try.

Re: Damaged Philosophers Tone
Here's the schematic

The grit control is a pot panning between 2 opamp outputs so you could bypass it with a fixed resistor wired from pin 7 and 1 of ic3 to the 2.1k on the other side.
That might not be your problem and it might involve drilling through traces on the circuit board.
Can you get a pic of the insides in case it's something obvious?

Re: Damaged Philosophers Tone
This sounds much like my experience with the Philosopher's Rock. It resolved completely with a dedicated 18V power supply.

Re: Damaged Philosophers Tone
Yes. A shot of the inside could tell us more if it is indeed something obvious. Looking at the schematic, you could bypass sections of the circuit if need be. It would require desoldering a combination of resistors and capacitors from various locations on the PCB depending on the section you're wanting to isolate.NippleWrestler wrote: ↑Wed Feb 17, 2021 9:19 am Here's the schematic
