This little Donner Digital Octave Guitar Effect Pedal does everything I hoped it would and does it better than I could have expected.
I am not doing any preforming or even recording, just working off stress with an acoustic/electric Ovation, Fender Acoustic Amp, TC Ditto Looper and this octave/detuner/harmonizer pedal.
The pedal can change the pitch of a note by 2, 3, 4, 5, 7, 12 or 24 half-steps up or down. It can also detune by increments of partial steps. Separate pots allow blending of the processed (wet) and unprocessed (dry) signals.
There are combinations of switches, dials and volumes that make weird noises but here are, for me, the most useful settings when coupled with a standard 6-string guitar:
Bass Guitar: Selecting “Flat” on the switch, "1 Oct" on the dial, and turn the Dry volume down to zero.
8-String Bass: Same as bass guitar but add some Dry volume.
