FAQs

What does a treble booster like the John Hornby Skewes Treble Booster do for my guitar tone?

A treble booster enhances higher frequencies, adding brightness and clarity to your guitar tone. It can make your guitar cut through the mix better, especially in live settings, and is often used to drive tube amplifiers into a more dynamic and responsive overdrive.

Is the John Hornby Skewes Treble Booster suitable for all guitar amplifiers?

This treble booster is particularly effective with tube amplifiers, as it can push them into a natural overdrive. While it can be used with solid-state amps, the most notable tonal benefits are usually experienced with tube amp setups.

Can the John Hornby Skewes Treble Booster be used with both single-coil and humbucker pickups?

Yes, the treble booster can be used with both single-coil and humbucker pickups. It is versatile enough to enhance the tonal characteristics of either pickup type, adding brightness and definition to single-coils and clarity to humbuckers.

How does the John Hornby Skewes Treble Booster compare to other boost pedals?

Unlike standard boost pedals that increase overall volume, the John Hornby Skewes Treble Booster specifically enhances treble frequencies. This makes it ideal for cutting through the mix and adding presence, especially in rock and blues genres.

Deep Purple

Verified via Hit The Lights

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.
