So I use my TC Electronic Sub'N'Up Mini for an effect somewhat similar to that of playing an 8 string bass, that is a bass with pairs of respectively bass and octave strings, and I think I have succeeded at making a custom toneprint that comes about as close to a natural sounding 1 octave up sound as is possible by just using a simple octaver, so though I would share it with you. Mind it doesn't sound exactly like a guitar, pitching up your signal a whole octave with nothing additionally done to it other than EQ is always going to sound somewhat artificial, but close enough for it to quite decently work in a mix as a faux guitar (especially if you are going for an overdriven guitar) or faking an 8 string bass. Also expect it to sound most realistic on the 2 highest strings and most artificial on the low E (and eventual low B) string. So here we go (Faux Guitar/8 string bass Toneprint): First load the "Deafult Poly" template, then edit it as follows : 1st tab : Row 1 : -100dB :-: -100dB :-: [OctUp level] :-: [Dry level] Row 2 : [Drive Gain OctUp] (even if you want a clean octave up tone try and see how +2dB works) :-: 0 :-: 0 2nd tab : Row 1 : LoCut = 35Hz (you might be able to get away with 40Hz too without affecting tracking on the low E, or in case you are using a 5 or 6 string bass with a low B you will need to set it to 30Hz, or even lower) Row 2 : HiShlv = 12.5kHz :-: -20dB :-: 12dB 3rd tab : Row 1 : LoCut = 20.0kHz Row 2 : [Bypass] 4th tab : Row 1 : LoCut = 20.0kHz Row 2 : [Bypass] 5th tab : Row 1 : LoShlv = 4.50kHz :-: +2dB :-: 9dB Row 2 : HiShlv = 8.00kHz :-: -20dB :-: 9dB 6th tab : (no adjustments) 7th tab : Sub/Sub 2 [knob assigment] : (this/one of these knob(s) can eventually be assigned to [Octaver - Drive Gain Up], otherwise clear all eventual other assignments) Dry [knob assignment] : (assign to [Octaver - Dry Level] and clear all eventual other assignments) Up [knob assignment] : (assign to [Octaver - Wet Level Up] and clear all eventual other assignments) Save the toneprint under whichever name you'd like and then save it to the pedal. You might get better results if you run a compressor right before the Sub'N'Up, otherwise keep the Sub'N'Up as the very first unit in your signal chain after the bass (except for an eventual tuner). If you try this Toneprint out please post a reply in this thread with how it worked for you. Other suggestion on how to achieve as natural a sounding 1 octave up faux guitar/8 string bass effect is of course welcome too. @yakmastermax You might want to try these suggested toneprint settings if you are still looking for a faux guitar sound and still owns your Sub'N'Up pedal, I changed some EQ settings compared to the last settings I suggested to you, and in my opinion this gets considerably closer. As I mentioned above it is still not 100% completely realistic, but it might still work for you, at least I think this gets pretty close.
