Re: Boss Super Octave and Acoustic Sim
I have the older AC-2, which was recently discontinued and replaced by the AC-3. The only difference I can see is that the AC-3 has built-in reverb, but I already have a few reverb pedals. Having an acoustic simulator effect is fun since it gives you a totally new tone from your electric guitar. But if you already own a solid equalizer, you can get acoustic tones which are more customizable.
The OC-3 is a really awesome octaver. People insist that the older OC-2 sounds more natural, especially the older models which were made in Japan. I haven't had the opportunity to compare the Japan version, but I didn't notice much of a difference between an OC-2 and an OC-3 on "OC-2" mode. In addition, the OC-3 has a polyphonic mode, which makes it a lot of fun to use, especially for that price. It works well with a single output to my guitar amp, but the extra output lets me send the processed low octave sound to my bass amp and get EQed separately from the dry sound, to which I can apply different effects.
