Hi,
the Maxon CP101 Compressor is an higly regarded opto-compressor. If someone is interested in analysing the circuit here it the schematic and the PCB layout.

This Schematic is for the vintage red Maxon CP101 Compressor.
The new black Maxon CP101 Compressor has the same circuit but some added features, it has a input buffer, fet switching if I recall and uses 4558 instead of 741.

Hi there,

I was just wondering if anyone knows how to mod the attack of this pedal.

On the Maxon website there is advertised a " Subtle Squash Mod ". ( as well as a super squash mod ).

can anyone figure out what this would involve ?

Thanks in advance.

Are they offering those mods for that pedal?

The strange thing is , theres no way of contacting Maxon themselves. you have to go through godlyke the distributer. I remember asking before when only the subtle squash was advertised. They replied that they couldant contact anyone who knew how to do the mods anymore.

i went back on the site recently and they have now added super squash mod - so i dont know whats changed. Ive shot them a mail but not very hopeful for an answer to be honest.

it would be great to be able to add an attack knob.

I've contacted Maxon directly in the past using this email:

maxon5@maxon.co.jp

There's also this one, but I got no luck:

sales@maxon.jp
