[2860] P-Comp Prototype

Date: August 21st, 2023 | Comments : [1] | Categories: DIY.

Another pedal prototype in a metal electrical box from around 2000. This box is interesting because I did not have a metal cover for it, so I made one from a piece of aluminum diamond plate that I had in my shop.

[2854] Dual Boost

Date: August 15th, 2023 | Comments : none | Categories: DIY.

The heat wave has passed (temporarily) and I could go back in the garage and dig through the boxes. Here is another pedal from decades ago.

This is a dual op amp booster that was the predecessor to the dual op amp pcb that I sell on my site. I’m not sure how old it is but it pre-dates the internet! I used this pedal sometimes when playing live.

A tap of the footswitch toggles between the two channels that can be set for different gains.
