This is a single germanium full range booster, co-produced by famous Grammy Award winning producter-writer-guitarist, John Shanks. Based on the Dallas Rangemaster, used by big names like Brian May, Eric Clapton, Richie Blackmore, and Tony Iommi, we put in some tweeks with the advice of John which then added a Sola Sound Tone Bender Professional mkII vibe, which Jimmy Page used to rock in Led Zeppelin, giving the Shanks a hybrid characteristic.

For the sound, we used hard to find vintage hand picked N.O.S condensers. For the power outlet, we use start of the art tech, which allows for that great sound with a noiseless boost and larg head room.

On top of that, the Brass knob makes the low to mid sounds boost to create this full range booster. From a clean sparkle, to a crunch and at full boost, it can drive like a tonebender.
