Old school Morley Evo-1 Echo/Volume pedal, uses a spinning "oil can" containing LB-65 lubricant, which I'll include a 4 oz bottle with purchase. This unit is currently partially functioning hence, the low price and is listed as repairable or as parts. To get an idea of how these sound, there's a Reverb listing with a demo available. It's complete as far as I can tell, it uses a belt and a tire (?) both are available on ebay and both need to be replaced. There are detailed instructions available online to change the oil in the can including the amount to be used. These units are pretty rare and pricey in working condition, you can verify that by looking them up. I believe I've priced this one fairly but I'm willing to entertain reasonable offers. Thanks for looking !
