Williamson is known primarily for his use of Gibson Les Paul Custom guitars, but he also plays other guitars live (although Les Paul Customs are his guitar of choice). Williamson says that all the songs on "Raw Power" were written in his London bedroom on a Gibson B-25 acoustic and the acoustic guitar used in the studio was a Martin D-28. A Vox AC30 amplifier was used for recording "Raw Power". Williamson says he plugged his Les Paul Custom into the AC30's Top Boost channel, volume at full and bass low, and played primarily on the Custom's low-impedance (hand wired) bridge humbucker pickup; no effects pedals were used. Williamson often used Marshall amplifiers when playing live in the 1970s, and recently switched to Blackstar Amplification's Artisan 30 for live use.
