So I have purchased a Composite Acoustic GX. I love the way it plays and sounds. I play in a rock band and some of our songs are acoustic based, so I play a live acoustic rig. I bought a QSC K12 and I have a LR Baggs parametric DI. I have a couple of problems.
1. When I play unplugged, I like the sound of the guitar, but when plugged in, I feel the sound is sterile and unpleasant, not warm in any acoustic way.
2. When my bass player starts to play, it vibrates through my guitar to the point that I have to hug the guitar to my body and it creates feedback, especially when I play bar chords. I get a vibration in the strings that carries into a feedback. So I find I play less and dont enjoy my performance.

So, do I give up on this guitar and get something that will be better for a live gig or should I try to improve on this setup if so, how?

Any help with this would be greatly appreciated. I have a show this week and would love to have an improvement soon.

Thanks VictorV
