I'm looking for a preamp or multi-effects pedal for acoustic/electric guitar that will allow me to do the following: 1. Boost the volume for solos (would prefer stepping on a switch for a preset volume boost). 2. Improve the sound quality, whether by acoustic modeling, sweetening or whatever). 3. Add reverb. Other features like tuner, effects and so on would be nice but not essential. Any recommendations? I have a Taylor 114ce and it sounds good on its own, but I'd like to have a volume boost at the least. I tried a Boss GE-7 for this and didn't like it because the volume control was too sensitive for my needs. I currently have a Baggs Para Acoustic DI and it's a great-sounding unit (especially for my Epiphone Les Paul Ukulele which has a passive piezo pickup that sounds pretty bad on its own) but I have to keep reaching for the little volume knob to make adjustments, which can be impractical if not impossible at a gig. Would like to keep the cost down but if I have to spend more money to get what I want, so be it.
