Final part of the modifcation to Boss CS-3 compressor. Definitely worth the wait. Tayda order and guitarpedalparts order came in to finish this mod. I tried testing and stacking different IC chips, including TL062CP, TL072CP, RP4558P and OPA2134PA.

Results of IC Stacks:
The TL062CP and TL072CP were a bit noisy, stacked with each other and the RP4558P.
The RP4558P stacked with itself sounded pretty good, some noise
The OPA2134PA stacked with a RP4558P, the quietest one. Really sounds amazing with this combo. I can see why OPA2134PA is so expensive.

Last Cap changes
C1 100uF 16V 105C JRB Radial Electrolytic Capacitor 5x11mm SKU A-972
C8 4.7uF 35V 105C JRB Radial Electrolytic Capacitor 5x11mm SKU A-974
C3 47uf 10v same value, just replaced with from my shed, forgot to order a aluminum cap on Tayda

Totally pleased now with the modifications. Sounds so much better than stock, no noise or hiss, comparable to an optical compressor but with better punch. Yeah this is staying on my board as always on.

So if you are going to this mod, you can buy the Monte allums mod that changes both IC chips or you can just by his adaptor on Reverb and by your own IC chips. Or you can just replace all the caps to save money, that will take care of most of the noise. Totally can skip replacing all the resistors. Just did it for kicks. Wouldn’t say it improved noise. And the Diodes, definitely would change if you want something warmer.

This pedal builder from Australia is sending me a compressor he built. He shipped to me for free to test out, will definitely compare it to this. It has a release knob on it. All my changes listed below. Lol Boss should just release these mods as a waza craft compressor, you know they would sell a shitload.
