The discontinued Ampeg Sub-Blaster was a really nice and sought after octave down pedal. It was made in very limited numbers. Even the reissues are nearly impossible to find these days and if you do, they're very expensive. They came in a fairly large, heavy (3lbs!) and bulky enclosure. My version is in a much smaller, pedalboard friendly 1590B2 enclosure (same outer dimensions as a 1590B but 4mm deeper) with all WIMA capacitors, all top jacks and a relayed true bypass. Due to the complexity of the build, and the rarity of the now discontinued components, I am only going to offer this last one of this version for sale.
UPDATE! (11/19/25)
I just found a few more Jfets to build one more of them!
