I've been looking into getting a boost pedal, and of course...so many choices...so few places to try them out. So, anyone have a chance to mess around with the Micro Amp Plus on bass? If so, any comparisons to the original? How helpful are the tone controls on bass? Dunlop's page is missing the manual, so I don't know at what frequencies they set the controls. Music stores around here suck, so no chance to try before buy, of course. I haven't ruled out other boost pedals either, so if you have any thoughts on alternatives that work great for bass, I'm open to suggestions. Someone in another thread had mentioned a Spark Mini as well. Any thoughts on that one? Thanks in advance!
