Buy It. I love this pedal. Your practice sessions will improve dramatically. With the amount of time I can dub, it's perfect for the price.
Just received this pedal a couple days ago and it has already expanded my line up another high quality product and I am highly pleased with the purchase i just took a chance on it after purchasing the noise gate and definitely would recommend this pedal - thanks!
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.
I've owned the Ditto and Ditto X2. Both were good pedals but had a tendency to get dark and muddy after a few layers (overdubs) were added to the first loop. If I added five or six layers, my songs turned to soup.
This little guy (and I do mean little!) somehow maintains fidelity and the loop layers stay clear & crisp. Best of all it has all the features of the X2 (which ranges from $180 to $250 new) for approx just $60 bucks in a foot print about a quarter of the size.
I don't know how they crammed it all in there but I'd say this is better than the more expensive X2 unit mentioned above.
Instructions are minimal & you'll need to download their software to export/import loops (this last part was omitted from my instructions).
