Hello from a long time lurker and first-time poster, In disclosure, my twelve year old son and I are recreational cellists (not bassists) but we have friends who are bass players. We find the outlook of bassists much closer to our way of thinking than six-string guitarists, plus we share the bass clef with this community. Here's our situation: I recently ordered a David Gage The Realist cello pickup for my son's 3/4 size cello. He plays in an electric string quartet that does mostly classic rock (Deep Purple, Led Zep, G&R, Coldplay), some 60's folk and assorted pop. I'd like him to begin learning jazz, blues and Celtic music skills. As total newbies to electronic sound spaces, we are considering options to enter the 21st Century with his cello. A multi-effects processor seems the obvious way for us to dip a toe in electronic musical waters, hopefully without risk of electrocution. Which processor should we begin with? I read multiple threads about Digitec's BP355, Zoom B2.1u and B3. As I got further into reading and listening to sound samples I began to wonder whether we might be better off with a guitar processor instead of a bass processor. The majority of cello notes center around middle C4 +/- one octave, with the lowest note at C2. As such, we probably wouldn't benefit much from the rich bass tones of a BP355 or B3 and we may be better off with one of the popular guitar processors. As a side-question, we are weighing the pros/cons of integrated expression pedals versus adding a separate expression pedal, or modifying a volume pedal as an expression pedal: http://www.strymon.net/2011/10/10/strymon-tech-corner-3-volume-pedal-as-an-expression-pedal/ So, what do BassTalk Forum members think we should do? — get a bass processor (Zoom B3, Digitec BP355, etc.) or a guitar processor such as Zoom G3 / G3x? A third option is to save money on an older/used guitar processor like Zoom G2.1Nu until we figure out what our actual needs are. Newly arrived electric cellists appreciate the BassTalk community's guidance.
