I don't remember whether this is one that Humphrey modded, or one that I modded on the same principles. Either way, I added a much larger input cap than the first-version "Atom Smasher" from Humphrey, so it allows more bass in. Review is here:

How about $65 shipped.
The only trades I'm interested in at this time are compressors that I haven't reviewed yet, or the Barber Tone Press (which I
did review but I need to update that review), or certain uncommon overdrives, or high-quality cables e.g. Belden, Canare, Mogami, but no Monster.
