You really have to think old school to appreciate what the Treble Boost has to offer, as it does pretty much what the name implies. Plugged into the front end of a moderately gainey tube amp—like the early Marshalls and Voxes used by Clapton, Page, and Beck in the ’60s—the Treble Boost kicks down a strong, bright signal that pushes the first gain stage into clipping—adding little or no transistor grit of its own. I found it worked great for overdriving all of our test amps, but a master volume model is recommended as this pedal jacks up the volume substantially when the Boost knob is up three-quarters or more. The Treble Boost’s voicing switch gives you three degrees of treble intensity: Treble 1 is less bright than Treble 2 (which also has a bit more gain), while the Mid setting offers the warmest response and the most gain. With a little experimentation you’ll be amazed by the sweet overdrive tones you can get with this pedal—such as a snarling Bluesbreakers-era Clapton vibe with a Les Paul. It doesn’t bang you over the head like most distortion boxes, but what it does is kind of magical and makes you realize why so many British guitar stars relied on treble boosters to get their sound.
Kudos Excellent vintage-style overdrive. Superb build quality. Voicing switch adds flexibility.
