Found a great deal on a used Ampeg Sub Blaster from Guitar Center Used Website. You rarely find them used, as they are no longer in production, and they are fairly pricey when they do appear. I was lucky to snag this one fairly cheap.
After playing it tonight, it is definitely the most musical octave I've ever played. You could definitely hear the difference between it and the Boss OC-3 that was on my board.
That being said, the low E did cut out a few times on the octave. The dry note went through, but the low octave would cut in and out when my picking attack was light. Needed to really dig in to get it to pop through.
Further, I thought the pedal was even better when running it with my Fulltone Bass Driver acting as just a clean boost. I think I'm going to try it with some form of actual clean boost to enhance the attack a little more. Maybe an MXR Micro Amp or something similar. Maybe someone has an opinion on this tactic. Seems like it just needs something for a slightly more focused attack when the octave is at a higher level than the dry signal.
