Roland RE-501 Space Echo + Chorus ... Possibly the cleanest you will locate. I'm gonna upload my collection of Space Echoes in the following married couple of weeks. I have them all if you're looking for one in certain. This RE-501 works excellent except the reverb is a bit noisy. It's been on the rack with its Roland friends for the last 10 years.
Possesses a newold stock Roland spare tape.
$1200 ... I can ship anywhere if desired.
