This is splurging for me. So far, my single biggest purchase item for my bass habit. Actually, it's like it didn't cost anything. I sold 2 basses, a guitar , power amp, and some speakers that covered it, but who's adding? I don't have it til 4/05 but I have a CA-9 that I just couldn't get myself to try some preamps thru, except the line out of my Yamaha bbt500h. I like the idea of less complexity with the head vs pre/power. Anyway, is there any reason I need to hang on to the Crest? I have a Schroeder 410 swallowing all that finely honed current. I originally got the ca9 to drive the 410, not that the yammy couldn't but used the yammy pre cause I like it's features and tone. My (light) weight rig is my Yamaha b500h + 2 EA wizzy's.
