Ok, so I don't get too razzed about yet another pedal, I think I am "pedal neutral" on this (like carbon neutral, but with pedals) as I just sold an older Nobels ODR-1 to allow this into the fold. End result: Pedal neutral, cash positive - #winning What do I like: - Supposed to be smaller footprint version of the Maxon OD820, which gets very high marks. - additional low end, but not muddy. Maybe along lines of Full drive, but not sure as I haven't compared - I'm sure someone whose read the schematics could chime in and say. - Less mid-humpy than the typical TS, but still has that mid-range honk. - Brighter LED than a TS9 - you can actually tell it is on!! - 9v setting has a nice bite to it - more reminiscent of my Ibanez Super Tube STL (Master/L Series, 1985) than a regular TS-9 and I like that a lot. - Aggressive at 9v, more so than a TS but perhaps not as much as say a Jet Driver or the Maxon ST9 Pro+ What I don't like: - 18v has a soft edge to it, not like the bite with 9v setting - surprised me a bit - does not cut as well. I thought 18v would add clarity, but it seems to take it away, soften it (I checked the manual to verify switch position.) - Pea green paint choice - prefer the color of the OD9 Pro+ much more. Included a video down below comparing the Maxon pedals - helped me decide on this vs the OD9 Pro+ for a TS-style pedal - it is totally splitting hairs. I like the fuller low end on this one.
