SCAMMER WARNING: Due to a spate of recent scam attempts (some successful) recently, if you're doing a deal in the classifieds, ONLY USE PAYPAL GOODS AND SERVICES UNLESS YOU KNOW THAT INDIVIDUAL PERSONALLY. It's really not worth saving a few quid.
This is a pretty useful bit of kit that attaches to the tone and volume pots in a Strat style 3 control setup. It's totally passive so no batteries,and it lets you get Tele-ish, acoustic and even fatter LP type sounds out of 3 singlecoils.
No use for it myself so on it goes; Google Hohner ATN Jt60 to see a scan of a sheet with all tonal options on!
