HammondDave has asked me for some comparison clips of the Burn Pedal vs the Ventilator Pedal that we've all come to love. I did a very quick comparison this afternoon with my MOJO and my Ventilator and the new Burn pedal. I always liked the kind of burning 122 sound that Gregg Rolie had in Samba Pa Ti, so I recorded two different MP3 tracks with me doing a verse/bridge from that song for comparison (with nice sustained chords). The OD gain and setting on the Burn and the Ventilator are both about 60% and they seem to have about the same amount of effect on each.. I didn't bother trying to match EQ or leslie settings precisely because you just asked about overdrive so the speeds, ramp up/down, or any of the other parameters that are available in the Burn haven't really been tweaked. Both clips are the Mojo with the exact same settings, and they're recorded directly into Sonar with no effects whatsoever.
So here's a 1 minute clip of each effect. I will hold off telling you which is which (some of you will probably recognize the Ventilator) but I think the two sound surprisingly close, and I basically just took the dirty 122 preset on the burn and dirtied it up a bit more to match the setting I had on the Ventilator.. There's lots more tweaking that can be done in the Burn, and I think you can get the Burn pretty close to the Vent, but the Burn has a bunch of extra effects, features etc, that will be meaningful for a some clonewheelers!! Here are the two clips..
