Effect of delay and reverb combined or not digital.
One of the first digital reverb pedal.
manual edits are as good pedal potentiometer.
a dosage effect (mix)
a repetition rate (time) or tone (reverb)
a long reverb / delay
the fourth contains numbers from 1 to 11: 1 to 3 the maximum delay of 32 ms to 2000 max and 4 combination of delay + reverb, reverb and 4 romm1, hall, flat 2.
6.35 a mono jack input, two outputs (stereo).
Model foot stomp, in 9V power supply or by foot (which drains quickly), or stabilized power supply type boss.
it's tough! mine at least 15 years.

UTILIZATION

Setup is simple, once you read the manual
the edition is quick and easy, not to put too much.
the manual is clear.

SOUND QUALITY

Actually it's no longer Digital snapping cold but very very effective.
I use it with a guitar behind the boss mt-2 or even behind a jmp-1. It works with low too.
I use either the time or the reverb, but more rarely combined.

OVERALL OPINION

I use it for about 15 years at the time it is the only existing. I left in a corner to use it from time to time. it still works.
at the time it was worth 1200fr!
with the experience I prendaris two pedals, reverb + delay.
but it does its job.
