Roland RE-201 Space Echo
This legendary tape echo unit is in excellent condition, and has been fully tested. From organic, warbly delays to intense self-oscillation soaked in reverb, the RE-201 is endlessly fun. Many pedals and plug-ins can replicate the Space Echo sound, but there's something undeniably magical about physically interacting with these machines. It's impossible to go wrong with this as an addition to your studio.
