EDIT: Afterlife Compressor is SOLD! My new Zoom B3 is replacing all my pedal, so they're all up for sale. Here are two mini (1590A) pedals I've built. First up is a Tube Screamer. This is a normal Tube Screamer circuit that I've shrunken down to fit in a 1590A box. This has the bass mod to allow more low end. Here's a quick sample: The other pedal is on optical compressor based on the John Hollis Flatline. This is a very simple, yet very useful compressor. I found it to sound better than my original-era BBE Opto Stomp. Here's a sample: I'm asking $60 shipped each.
