I just picked up a Zoom A3 acoustic guitar processor and I thought I’d share some info about it since I know many BeatBuddy users are acoustic players as well. I bought it because I hate hate hate what pickups do to the sound of an acoustic guitar: piezos respond only to the vibration of the strings that pass through the bridge, magnetic only respond to the vibration of the metal of the strings. In either case, you loose the vast majority of the warmth and resonance of the body and the rich harmonics almost vanish. Also, if you’re plugging into a mixer not using a direct box or preamp of some kind, you’re quite possibly also losing the guitar’s brilliance due to impedance mismatch issues.
The Zoom A3 uses modeling to make pickups not sound like pickups. You chose a body type and a model type that best suits your guitar and you can store several different presets if you perform with more than one instrument. It also has a mic input so you can have a mix of direct sound and pickup signal. The processor has a set of equalizers, compressors, reverbs, choruses, etc. to help find just the right sound.
I’ve never been pleased with the sound of my acoustic guitars when highly amplified, they sounded metalish and harsh, not woody and warm, until now!
