I just finished building this compressor for a friend of mine, and it is amazing.
The pcb is extremely well designed, it suits my needs perfectly.
I used the Ross values and a pot for the attack function. Kept the default values for the treble switch, which is very useful in my opinion.
Compared to my other Ross compressor (HBE CPR), it sounds slightly better to my ears, and can be more versatile thanks to the attack knob (my HBE only has a trimpot for that) and the treble switch. Plus mine has top mounted jacks and dc jack!
I drilled a hole in the back of the pedal to access the input trimmer, just in case.
It’s my second aionelectronics project, and it won’t be the last. Great job designing the pcb guys, thanks a lot for your great work.
