So I already own a Sub'N'Up Mini that I use as an always on 1 octave up polyphonic effect to mimic sort of an 8 string bass effect. However I suspect it to be the cause of the huge random tone changes I experience, I am looking into this issue at the moment, and expect my to have reached a final conclusion tomorrow. If it turns out it in fact is not at the fault of the Sub'N'Up I will get pretty frustrated as I seem to have rules out anything else by now, pickups, jack output socket, headphone amp, headphones, patch cables, instrument cables and other pedals, but I'll be keeping the Sub'N'Up at least, as I am actually really satisfied with the polyphonic 1 octave up effect I have dialed in via the tone print editor, practically flawless tracking, almost unnoticeable latency and in the mix sounding pretty close to natural. If the conclusion however turns out to be what I expect, that my Sub'N'Up is faulty I am seriously pondering on looking elsewhere for a replacement, and I pretty much narrowed that down to the T-Rex Quint Machine, as the octave up of that also seems to sound pretty natural, unlike the somewhat organ/synth like tone of the EHX POG pedals, and I expect to be able to push it's octave up tone the last bit of the way to perfection by placing it in one of the effect loops of my Boss LS-2 with the 1 octave up effect full on and an equalizer placed after it, and then use the LS-2 for clean blend. Will be a bit more circumstantial and take up a bit more space than just a Sub'N'UP Mini would, but that wouldn't bother me as long as I can achieve as great a result as with the Sub'N'Up, which brings me to the question, how does the latency and polyphonic tracking (including double stops and chords) of the 1 octave up effect on the T-Rex Quint Machine compare to that of the Sub'N'Up Mini, and would I have any reason to believe it being less prone to go faulty down the line? I should maybe point out that while I am going for an always on 8 string bass effect I prefer the tone of the octave up to be less bright and a bit lower in the mix than it typically would be on a real 8 string bass, and the Toneprint I managed to dial in on the Sub'N'Up Mini that I use currently pretty much nails that spot on. What does people who have experience with both say, Sub'N'Up Mini, or perhaps the regular bigger version, + Toneprint editor, or Quint Machine + Boss LS-2 + equalizer, for a natural sounding always on 1 octave up effect? And just to get that out of the way I wasn't happy with the job the Digitech Ricochet, that I tried out before I got the Sub'n'Up Mini, did, and I don't like the somewhat organ/synth flavored tone of the octave up on the EHX POG pedals.
