BTU-500 True Bypass Stage Tuner
The Boston BTU-500 True Bypass Stage Tuner is a must-have for any serious guitarist looking to keep their axe in perfect tune, without adding unwanted coloration to their tone. This robust, road-ready pedal packs professional-grade tuning capabilities into a sturdy metal housing, making it a reliable companion for both studio and stage. What sets the BTU-500 apart is its true bypass design. Unlike many tuners that color your sound even when bypassed, this Boston unit seamlessly routes your guitar signal around the internal circuitry, ensuring your precious tone remains uncompromised. That means no unwanted buffering, capacitance, or impedance changes - just pure, unadulterated guitar goodness when you disengage the tuner. The BTU-500's bright, easy-to-read LED display provides super-accurate tuning, with precise pitch detection that can handle everything from standard tuning to the most adventurous open and drop configurations. And with its silent switching, you can tune up between songs without that annoying pop or click interrupting the flow of your performance. Rumor has it this tuner was a secret weapon for blues-rock icon Stevie Ray Vaughan, who relied on its bulletproof reliability and pristine tone transparency to keep his Stratocaster in tip-top shape during marathon live shows. If it could withstand the rigors of Vaughan's electrifying stage presence, you can bet the BTU-500 can handle whatever you throw at it.
