I'll chime in again - I've been enjoying the OFD as well. I've got a great Muff sound. Using a Tonebender style sound for another part. I was also able to dial in an SFT-style sound with the Crunch Tube (I use the SFT has a raging overdrive, so it's high gain). I've got a ton of dirt/fuzz pedals, but as a test I'm taking a bunch of them off my board to see how much the OFD can really handle. Rat Tail, SFT, TAFM, Colossus, Barbershop are all sitting on the shelf right now). It can approximate a lot of those sounds, although I can't get anything that sounds exactly like a Wooly Mammoth or Oxide yet, so those are still on the board. Although the Gated Fuzz on the OFD is cool, it's has it's own flavor.
Source Audio was kind enough to supply me with a prototype of the Midi HUB for testing, so I can store up to 128 presets and that's made this pedal incredibly useful on my board. It's really a steal for the price. With the addition of the midi hub, it's now got me looking at the Orbital Modulator and I want to check out the BEF if/when they come out with the sb2 version. So much control!
