So I got my Throbak ODB today and have been playing it all night. This is seriously good... and seriously different in some ways. I've never been interested in boost pedals. Actually, I didn't get this for a boost but because it could do both fuzz and overdrive, germanium and silicon. It was odd that it was pretty clean until the last third of the gain knob. That's about opposite all other pedals I've used. I enjoy both the silicon and germanium fuzz tones quite a bit, but it's my first fuzz and I can't personally compare to others. It's probably not super saturated fuzz, but moderately so. As a Colorsound Overdriver at heart, it does the cool vintage Jeff Beck tones, but IMO, it also does great Jimmy Page tones. It is funny to think that tube amps are often designed to get the Led Zeppelin tones when much Zeppelin tones were a combination of mild fuzz and overdriven amp. The ODB can get that sound incredibly well without having to overdrive your amp. I was interested in the ODB as possibly a high gain pedal for an alternative sound for Metallica type metal to Prog Metal sounds. It can get somewhat close, but could use slightly more gain for that, and the pre-gain would need to be set even tighter. I assume it could be done, though I'm not sure if the pedal's gain could be increased. But when I set it relatively clean as a boost, even if only at unity gain, it just sounds so incredibly sweet. Plus with all the silicon and germanium, pre-gain on or off it allowed a tone of minor variations that were excellent. Throbak advertized this as capable of an attenuator like setting. I see why he says so, but it still isn't the same as an attenuator. An attenuator allows you to get the particular tone of whatever power amp is cranked, EL34, 6L6, or whatever. But this setting does sound like a cranked tube amp more than just a pedal or even a cranked tube MV preamp. Up to that point, I've been playing it through my Pritchard, which reacts in all ways like the very best non-MV tube amps. I thought that if it sounded like a cranked tube power amp in the Pritchard set clean, what would it sound like in a plain jane solid state amp - my Carvin SX100D 1x12 with Texas Heat speaker? UNBELIEVABLE. Set clean it sounded better than, but similar to a Fender Deluxe Reverb RI. Or maybe I should say it sounded somewhere between there and a BF Bassman. But the oddest thing was that I really would have been fooled to think I was playing through something with a tube power amp. The clean tone with single coils instantly made me think of clean Jimi Hendrix. I prefered the pre-gain cut set to off (standard Colorsound circuit) for single coils. With humbuckers it worked well either way, but depended on other settings. Using a high output Tone Zone bridge HB, if set to germanium, even on the lowest gain setting it was already pushing into overdrive. That wasn't necessarily bad, because even the Tone Zone cleaned up incredibly well when rolling back on the guitar volume. But on he silicon setting, it could actually stay clean up to noon on the ODB gain knob. (Like I said, an unusual pot where most of the gain changes are in the upper 3rd of the pot.) Anyway, from playing this pedal into something like a Crate Powerblock may about the cheapest and most compact killer tone you could get. I don't know yet how other pedals after it sound, and I haven't tried other pedals in front of it. Being a fuzz it might not like other pedals in front of it, but Jon at Throbak thinks some (wahs?) might work in front if the ODB pre-gain is set to On. In comparison, I also have the V-Stack Classic. The V-Stack is not capable of tube clean tones. It has a great high gain Marshall tone that the ODB can't get, but in comparison, the ODB actually sounds much more like a real tube amp. The V-Stack doesn't have a clear tube power amp sound like the ODB, which gets them whether set clean or dirty. The ODB set to higher gain on the SS Carvin sounded great too. I would set it to germanium and get those great Zeppelin tones, better than any SS amp I've heard, excepting the Pritchard of course, which is so far beyond other SS and many tube amps that it doesn't count!
