Roland RE-501 Room Echo + Chorus ... Maybe the cleanest you will find. I'm gonna upload my collection of Room Echoes in the next few weeks. I have them all if you're looking for one in specific. This RE-501 functions best except the reverb is a little bit loud. It's been on the shelf with its Roland friends for the last 10 years.
Comes with a newold stock Roland extra tape.
$1200 ... I could deliver anywhere if preferred.
