Vintage RAT, MADE IN U.S.A. I've obscured part of the serial number in the images for this listing, but it remains on the unit itself. Based on my research online, I believe this is from around 1988. The pot dates also seem to be from '88. There is some rust and dirt, but there's no crackling and the sound is perfectly fine. As this is a vintage item, please understand and accept the "no returns, no claims" policy before considering a purchase. I cannot ship on Sundays, but I will ship on the same day or at the latest the next day after purchase. Please take this opportunity to get your hands on the classic USA RAT sound. Thank you.
