I designed a Gretsch “Triple Jet” by adding a third pickup to a Double Jet, and putting an MXR Micro Amp inside the guitar. You can instantly get an overdriven sound by clicking on that pickup. You can just plug into an amplifier. If it’s time to play a solo and break out a little more, just click that switch on the guitar. I had everything for that band made out of copper. All the pedals were made of copper. I had a copper microphone, and I had the guitar made of copper. We even went as far as putting copper frets on that guitar—just to see how it sounded. It sounded incredible! But copper is so malleable that the frets wore out after one show.
