Re: Anyone using the Zoom PFX-9003
I've got it and I love it. I had owned the Zoom G2 (bought it a second time as well) and really expected the 9003 to sound similar. Personally, I think it sounds better. Great variety of effects, easy to use, great sound, very portable, run time on batteries could be better. If it were lost or stolen, I'd buy another one in a heartbeat. I've never been a huge Zoom fan (feel they are the low end of the market) but this thing rocks.
I also owned and RP80 (believe it was an 80, maybe the 50). You're really looking at two different beasts (one a footpedal, the other a cigarette box). The RP was ok, but nothing fantastic.
Get the 9003. Just make sure you also have a semi decent set of headphones ($20 range or so).
