The studio is based around a 44-input Trident console and Yamaha NS40 monitors driven by a UREA power amp. The outboard gear on hand includes a Demeter mic preamp, two Neve mic and line amps, a GAL 5-band stereo parametric EQ, and a pair of Trident TSM EQ modules. "In the studio, I mostly use old single-delay lines, in pairs," says Holdsworth. "I have bunch of old Yamaha 1500's I use for that. The digital effects all date from the days before multiprocessors. The only multiprocessors I have are Rocktron Intellifexes, which I like a lot. But I use those mainly for live work. I don't actually own a really good reverb. I usually rent one when I need one. I used to have an AMS 1580S and RMX-16, but I sold those to Steve Vai a long time ago and could never afford to buy them back."
On his chordal accompaniments, Allan has been striving for a more "orchestral" sound, using layers of delays to get shimmering, pulsating textures from his sophisticated fingerings. "For my rhythm sound, I've designed a setup where all the signal processing is driven from one master board; I put each effect into one fader." His digital delays are two ADA STD-1s, two AMS units and a Yamaha E1010. The whole rhythm setup is run through a Yamaha PG-1 instrument pre-amp, some P2200 power amps and S412 speakers. The mixers are a Yamaha M406 and a M516. Allan also has an Ovation '83 Collector's Series acoustic and a Chapman Stick.
