Interesting Amp - 1967 K-200-4 model with 2-15" JBL speakers and a SM57 on the Cab - pretty sure he used the 3/4 scale 1969 Rickenbacker 325 Sunburst guitar with a Humbucker pickup in the bridge - he's probably the only guy who got that tone from the setup he had - the amp had the distortion circuit was called the Harmonic Clipper which is how he achieved it - still I've. never heard it duplicated.Does anyone have any idea how John Forgerty gets that tone on the solo from Heard it through the grapevine? Sounds like a tele or a strat on the neck pickup above the 12th fret, but there's definitely something else going on.
