[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.

The prototype of the Q&D 1 compressor. The schematic is still on my web site somewhere. It used the SSM2165 vca chip which is unobtanium these days.

Another ancient pedal from the boxes in my garage. This one has the same type LMB folded aluminum enclosure. It also uses the cmos switching system with a soft-touch footswitch.

[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.
