So I have a vintage 1980's Ibanez BP10 compressor. I'm surfing around EBay and see them being sold for $175 and up. Ibanez product sites say it's not very collectable, and Bongo's compressor reviews says it's another Ross clone with one capacitor switched out. I listed mine for that price once and got no bids. So whassupwidat? Is this a case of people taking advantage of others with the "vintage' label or is there a value to this pedal which I can't see?
