I'm hoping you guy can give me an idea given the situation. I've posted this on a guitar effects forum and received zero responses. Here's the deal. I'm upgrading my current rig from an Ampeg BA115 combo to the following: Sansamp RBI (pre amp) Yamaha CP2000 (power amp) Avatar B210 Bass Cab Avatar B115 Bass Cab Now for my dilemma: I'd like to be able to use this rig to occasionally play guitar (not in a gigging situation, but more for practicing/writing). I'm looking for a decent multieffects processor that I can feed the power amp with to accomplish my goal. I've considered the Sansamp PSA-1, as it does guitar and bass; however, it doesn't have a mid control which I want. So...can ya help a brother out? Thanks!
