Treble Booster based on the Dallas Rangemaster, the secret ingredient for the legendary sounds heard by Eric Clapton in John Mayall's Bluesbreakers, Rory Gallagher, Brian May and Tony Iommi. Built from the greatest parts available (and not !), tropical fish capacitors and with carbon comp resistors for pure vintage sound ! The transistor choice is crucial for the Rooster, therefore Jam searched and found the best and extremely rare germanium transistors ever made : the CV7003, military-spec OC44 germanium transistors. Each individual transistor is measured for gain and leakage and then hand picked and matched through sound audition.

Playing with the guitar volume, you can achieve many sounds, from clean crunchy tone, to fat boosted overdrive ! Also, a lifesaver when in a dead-sounding-amp situation, where you can use it in front of the amp's input constantly on, to liven-up the amp's sound !
