Effects he used from 1970 to 1997, besides his usual tape echo, included a Hornby Skewes treble booster in the early days. Around late-1973, he experimented with an EMS Synthi Hi Fli guitar synthesizer. He sometimes used a wah-wah pedal and a variable control treble-booster for sustain, and Moog Taurus bass pedals were used in solo parts during concerts. He also had a modified Aiwa TP-1011 tape machine built to supply echo and delay effects; the tape deck was also used as a pre-amp. Other effects that Blackmore used were a Uni-Vibe, a Dallas Arbiter Fuzz Face and an Octave Divider.
"1970 - Same amps but I bought a Les Paul custom; it was a fake and didn’t stay in the collection very long! But I used it on Benefit. I started using a Hornby Skewes Treble Booster, which gave the HiWatts a bit of a kick. Unfortunately they picked up radio perfectly. Any gig within a mile of a radio station was a disaster!" - Martin Barre.

The SKEWER operates similarly to Catalinbread's Naga Viper pedal, but rather than being based on the Dallas Rangemaster, it is based on the Hornby-Skewes Treble Booster—another iconic piece of Blackmore's gear.
