Roland Chorus Echo RE-501 microphone pocket-sized tuning solution featuring aClassic Tape delay from Roland. The RE 501 along with the SRE 555 (rackable 501) were the last in the line of the legendary Space Echo tape delays from Roland. Its particularly nice on synths and vocals where I think it shines over the 201. Its in great shape other than the missing power button Which can be purchased from Exhofix.
