There has been a lot of discussion about this lately. I don't like the Electro Harmonix. I've narrowed it to either the Akai Deep Impact or the Digitech Bass Synth. I've tried the Digitech and been very impressed, like everybody else apparently. The Akai I've played a few years ago and found really a** kicking at the time. My memory may fail on me though. Programs are a nice feature, but is it worth the price difference ? Has anyone A/Bed the 2 boxes ?
