Spring reverb, 3 knobs, input and output jack, jack 9V

UTILIZATION

The first two knobs are not great thing is the settings for sound, effective, but they have a very small range. I prefer at least noon, but try.

The last knob is doing something, and after 2 hours it sounds a little too electronic.

I do not kick pad useful.

SOUND QUALITY

It's good for a little atmosphere, it's not for extreme effects.

OVERALL OPINION

The springs are too short to make sounds like the atmosphere of a large cave. Maybe not as good as spring reverb amps, but it's pretty cool.
