This is just idle curiosity mostly. I was talking with my guitar player this weekend. He works in the music trade press and is a pretty well informed, and sane kind of guy. For no reason in particular we ended up talking about Dumble guitar amps. I was astounded to hear that some of these amps go for $40-50k (!#@^!). I asked him what could possibly justify such outlandish prices and while he focused in on the unique tone qualities, unique circuitry, limited numbers and the fact they are totally hand built amps, plus some sort of mysterious Dumble "mojo", but I still could not get my head around the price. So, in any event, this made me wonder if there was any equivalent in the Bass amplification universe. I know of the SA200 and Koch amps, and I have heard of a few other boutique hand built bass amps out there, but heck, you can buy an SA200 for $3k or less (there are 2 in the classifieds right now). Anyone have any views on this ?
