Well, I wouldn't buy it. But its a fun toy to play with ( especuially if im playing progressive rock)
Where Obtained: Got it with my guitar
Twist Knobs, Delay length, Duration, Mix controls.
I use this with my Epiphone Sheraton, and at first I liked it. The signal stays good over repeats. However, it struggles on and sound apart from clean. Put it after a distortion pedal, and the sound quality is much diminished. Its fun to play a chord of whatever then play with the controls ;-)
Pretty easy, but you can get some feedback type noises.
