For sale is a Prescription Depth Charge. The manufacturer is already out of business, and it's impossible to buy it new. Also, not many were originally made, so it's rare to find. I imagine many of you have been looking for one? It's said to be in the Maestro BASS BRASSMASTER family, a powerful, roaring bass fuzz. It would be interesting to use it with a guitar as well. It's been used by tetsuya of L'Arc～en～Ciel, Chiyo Kamekawa of Yura Yura Teikoku, and Debbie Googe of MY BLOODY VALENTINE. I've confirmed it works with both batteries and an adapter. The battery snap wiring is different from BOSS and others, so the sound won't be normal if you use an adapter while the battery is in. This seems to be the specification. It has a fair amount of wear and tear, so it's not a collector's item. Please refrain from purchasing if you are sensitive to this. I hope to sell it to someone who will use it without hesitation. #Maestro #Brassmaster
