Treble Booster

The Shaftesbury Treble Booster is a compact, plug-in gem from the golden age of Japanese effects design. Conceived in the 1970s by the legendary Nisshin Onpa (better known as Maxon), this unassuming little box packs a powerful punch, delivering a bright, focused boost that's perfect for tightening up clean tones or pushing vintage amps into glorious, harmonically-rich overdrive. At its heart lies an analog transistor circuit that produces a sharp, cutting tone with just a hint of pleasing saturation. The secret lies in the "Treble V.R." control, a simple but versatile knob that allows you to dial in the precise amount of boost and high-frequency emphasis you need. Crank it for a searing lead tone that'll slice through the mix, or back it off for a subtle sparkle that adds clarity and articulation to your playing. What makes the Shaftesbury so special is its no-frills, plug-and-play design. Just connect it straight to your guitar's output, and you're ready to go - no bulky power supplies or complex controls to worry about. It's the ultimate grab-and-go treble booster, perfect for adding that extra edge to your sound whether you're recording in the studio or rocking the stage. Compact, sturdy, and oozing vintage charm, the Shaftesbury Treble Booster is a true unsung hero of the effects world. Beloved by players like Rory Gallagher for its ability to tighten up and focus his Fender-driven tone, this little wonder is a must-have for any guitarist seeking that elusive perfect boost.
