I compared the MK3 agaisnt the MK2 late last night..
I'm still a little confused to the function of this sub, is it designed to only engage when the octave (red) section is on? And if so what is the advantage of turning it off and on while the octave is off, to prepare the pedal for octave plus sub or vice versa? Ever since I got the mk2 I've been puzzled, even thought something was wrong. I would assume the sub would run "solo" like I hear others mention, just by itself. But anyway, I put them both in my signal, matched (audibly) what I thought were the same settings and found a few differences. I am in no way a veteran to this circuit, so I could be completely off but this is what I found. The 3 seems to definitly track better, and pick up to the sub low A notes. The 2 starts to die out at that point, flip back and forth (which is noted everywhere with octaves) when the 3 went all the way down to low E. Now I did have my volumn all the way up, Jazz bass 100% faded to neck PU to get this, its possible cranked the other way but you have to be easy on it. The MK3 seems ballsier and the sub almost rougher, matched up settings side by side, the output seems to have more range. The tone seems to have more range as well, in both directions, but not much. Now for some reason with Tim on and off, tone all the way counterclockwise, the MK2 seems smoother, even though the notes aren't as defined (or not even there) below A. I dont know if it's because the lack of this fuller range, or what, but I was able to dig in a little more and add my normal dynamic opposed to more tiptoeing with the MK3. I had someone ask if the sub had more output on either model, with settings matched (which could possibly not be right due to this difference in range) the output sounds the same, and in waveform looks the same in DAW. The boost of both channels did seem to have a little more headroom on the MK3 as well, which is kind of hard to compare with the fading system on the MK2.
I'm sure I'll find more things to say, I enjoyed playing both, still puzzled about the sub operation, I didn't just throw the MK2 to the classifieds like I thought I would, yet... but I like them. The new ones construction seems indestructible, very well built, design is spot on, graphics evenly applied and look to hold up better that the 3leafs in the past, pots super solid and bypass is quiet, on a side note I have my SVD back, and love it
It was 1am when I stopped or I would have posted clips, it was too late to render/upload ect
