RM-M Metal Treble-Booster
The BSM RM-M Metal Treble-Booster is a modern recreation of a true classic - the legendary Range Master, a cherished secret weapon of British rock royalty. Powered by the same rare OC44 germanium transistors as the original 1965 version, this pedal delivers the same blistering, harmonically-rich tone that defined the sound of blues-rock titans like Eric Clapton, Rory Gallagher, and Tony Iommi. What makes the RM-M Metal so special is its uncanny ability to coax out the most desirable qualities of your guitar and amp. Plugged into single-coil or humbucker-equipped axes, it unleashes a thick, punchy midrange and a searing top end that cuts through the mix without ever turning shrill or brittle. Crank the guitar's volume, and you'll be rewarded with a ferocious, touch-sensitive lead tone that practically drips with attitude. Roll it back, and a wide range of crunchy rhythm textures emerge, from vintage-tinged overdrive to modern high-gain. The secret is in the pedal's simple yet ingenious design. By strategically placing the RM-M Metal between your guitar and amp, you harness the synergistic magic that occurs when a treble booster interacts with your amp's preamp. The result is a remarkably versatile tone-shaping tool that breathes new life into even the most familiar rig. If you seek the holy grail of British rock tone, the BSM RM-M Metal Treble-Booster is an essential addition to your pedalboard.
