I just got my OFD in the mail a few hours ago, and have been fiddling with it quite a bit. I've got two other SA pedals (the Orbital and the Manta), and this one is by far much more difficult to dial in. My initial thoughts are as follows:
- Most of the so called tube distortions seem a bit too synthetic and square-wavey, with the exeption of the Tube Drive.
- The Smooth Tube is my least favorite. I've been using Mesa gear exclusively for 16 years now, and this doesn't really sound anything like any of the many Mesa amps I've owned. It sounds a bit closed off and muffled, and overly gainey. There's not much in the way of decent tone to be found even in the lower gain ranges.
- Most of the tube models sound best with lower gain settings - at high gain they all start to sound the same. The fuzz sounds are pretty good at high gain settings, but methinks they could stand for even higher gain.
- The Gated Fuzz doesn't sound much like my Wooly Mammoth. It's the one model that could stand to be more synthy and squelchy sounding.
- The range of the mix knob is too delicate, especially on the left side. Even with a totally raging distortion, if I turn the Mix knob to 9 o'clock the distorted tone disappears and I'm left with nothing but a clean signal. Finding a good in between tone with only the range from 9-12 o'clock is tricky and tedious.
- The octave fuzz is a bit too square wavey and actually not harsh enough on the high end - my B:assmaster blows this thing away.
- On the tubey side, the Tube Drive, Crunch Tube, and TS9000 are definitely the best, especially in low gain settings. They sound much more open and transparent than the Smooth Tube and Power Stage.
- On the fuzz side, I'm digging the Gated Fuzz and Metal tones, largely at the higher gain settings. The other fuzzes don't seem to have much of their own character, and kind of blend together.
Overall I'm on the fence, but I've only had it for about 6 hours. That said, I was completely sold on the Manta and Orbital in a matter of minutes, so I'm a bit surprised that I'm not immediately blown away by this thing. I'll continue to fool with it (or at least, I'll fool with the replacement - this one arrived with a dead LED) and see if I can fall in love with it or not. I really want to like this thing, as it could simplify (and expand upon) my gigging rig immensely. More knob tweaking awaits.
