The beautiful Boss CE-2 wears a coat of dazzling blue, sports a bucket brigade chip, sounds terrific and will set you back around $400A these days. The CE-2B is the exact same circuit, but with a 'level' control to blend the clean signal in. And, in a move that will please bass players, it's wearing snazzy brown.
