I've always been a fan of octave effects. I remember first hearing a Boss OC-2 when I was like 14 and I just had to have that sound. There was a bit of a learning curve when I found out about "tracking" (I was primarily a power chord guy at the time). After getting back into guitar after 25 years away, one of the first pedals I wanted was another octaver. After a bit of research I settled on a TC Electronics Sub N Up as it offered a lot of versatility having an octave up and both one and two down, plus the whole Toneprint thing. It was a nice pedal, but it's sounds never really inspired me, too "digital" and sterile, plus I found I didn't really use the sub octave or the Toneprint option. One day a few weeks ago I stumbled onto the Foxrox on Ebay, not actually really looking for an octave pedal. I had never heard of them and did a bit of reading and listening to clips, and was quite intrigued by what I read and heard. It was an auction so I waited till there was about ten minutes left and set my maximum price. There was a bit of a flurry but I got it (without going over my max bid). I've been playing around with it for a few days now and all the good things I read about this pedal are completely true. It's everything the TC wasn't. It's inspiring me in so many ways. It loves to have some fuzz and wah mixed with it too. The low octave is so organic and rich, reminds a bit of that OC-2 from my youth, but even better! The upper octave is what really surprised me though. It's incredibly musical and just makes every guitar I put though it sing and wail, throw in some wah and it's ridiculously good. If you're the kind of person who enjoys octave effects or are just looking for some new inspiration and aren't afraid to experiment, I would highly recommend this fine piece of kit. As a bonus, I sold the TC pedal a few days later for the same price I paid for it new.
