I got an amp - Spider III 75 Watt and I plan on getting myself an acoustic electric. Do I need a new amp? How would this have to work. Can't I just use the clean channal or do I need an acoustic amp just for this.
no urs will work fine
Yes, you can use the clean channel. It will sound just fine.
Acoustic amps just give cleaner sound at higher volume, but the clean channel will work fine, just dont expect to overpower anyone.
