The TO and Pro are different. It didn’t strike me when I first got the Pro, but it does now that I can compare it directly with the original.
The TO’s upper octave is brighter than the Pro’s, even with its tone control all the way up. The Pro has more of a mid-heavy sound, the original has more top end sparkle. I like the tone of the Pro a bit more, but the tracking on the original is slightly better.
The dry signal on the Pro is one of the pedal’s cons. It sounds a bit digitized and actually seems like the headroom is a bit low; there is some minor distortion but it’s low enough that you might only hear it with headphones (that’s what I was using.)
The original’s dry signal sounds way better, no question.
The sub octave is where the biggest differences reside. The original sounds worlds better, both in tracking and overall tone. The Pro actually seems like it struggles with certain notes (open D string, for example) and starts to flub-out as you go lower - the original tracks all the way down to low E without issues.
The Smooth/swell knob on the Pro actually works
really well, to its credit. Lots of usable sounds throughout its range.
Really curious about the mkII now, especially because of its analog dry-thru. Hopefully it’s closer to the original in terms of tracking, but with the added swell/tonal options from the Pro.
