"I'm trying to decide between a jam man or boomerang. I'll be using it for live gigs with my acoustic guitar. Which has better sound quality? I've heard the boomerang is easy to use, how hard is the jam man to use? Thank you." I don't believe the boomerang is for you, the sound quality isn't up to the level that an acoustic guitarist would want. It is by far the clear choose for electic guitar players. I haven't tried use an acoustic preamp peddle to sharpen up the sound yet. I play acoustic about half the time and I am still searching for a way to make the boomerang sound good. I might add, if you are going to use the sampler for solo stuff the boomerang is just fine, and would serve you very well. email@example.com and yes I am a postal worker.
