Sure, from 1989 ... he used a stock '59 strat with a maple neck as his main guitar, the only change was fret replacement to Dunlop Jumbos. His amp was built and designed by a San Franciscan named Jim Palermo who was a Hiwatt amp distributor at the time. He took a basic 50 watt Hiwatt's preamp section and incorporated a Vox AC 30's power amp for the power section. His pedal-board was a "Bradshaw" switching system about which Scott said the components used to match line levels were extremely high quality and this was a significant part of the tone he was getting. He used Celestion G12k - 85s, one in his main combo amp, and two in each of his effects cabinets. The main combo amp was run completely dry except for an Ibanez tube screamer.
This is from 1989 so I'm assuming it is okay to share this information. He did share it with a 'nobody' ( me ) after-all, that's why I went ahead with this.
As a p.s. he mentioned he was a Holdsworth fan also, so I must have mentioned him as one of my favorite players.
