The TrashCompactor is a VCA-based compressor pedal designed for studio-quality compression with a high dynamic range. It utilizes a bipolar supply for increased dynamic range and includes a JFET input buffer, volume output control, and dry signal mix. The dry signal mix adds high-end and sparkle to the output. The compressor offers an alternative to optical/transistor-based compressors commonly found in guitar pedals.

The TrashCompactor uses the THAT4305 IC, which is a QSOP16 package that can be difficult to hand solder. To make the project more accessible, there is an option to order the pedal with a pre-soldered breakout board that already contains the 4305. This means that builders only need to solder in pin headers and then attach the breakout board to the main PCB.

The controls on the TrashCompactor include:

– LVL: This is an active volume control/boost.
– COMP: This controls the amount of compression, ranging from minimal to extreme.
– DRY: This adjusts the amount of clean, uncompressed signal that is blended in parallel with the compressed signal.
– THRESH/GAIN: These trimmers set the threshold detection and gain recovery amount of the 4305. More details can be found in the notes.

Overall, the TrashCompactor is a great-sounding compressor pedal that offers a different approach to compression compared to other guitar pedals on the market.
