Vintage style Treble Booster, one of the secret ingredients that helped shape 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 some barely attainable !), tropical fish capacitors and carbon comp resistors for pure vintage sound !
The transistor choice is crucial for the Rooster, therefore we searched and found the best and one of the rarest germanium transistors ever made : the cherry-picked CV7003, military-spec OC44 germanium transistors. The CV7003 is extremely consistent as well as heat-resistant. Each individual transistor is measured for gain and leakage and then matched through sound audition.
Playing with the guitar volume, can unlock many textures, ranging from clean crunchy tones, 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 !
“…playing the Rooster through a good overdriven tube amp evokes some of my favorite classic tones and you get a great variety of sounds by manipulating your guitar volume…” Julien Kasper
“Rooster is an extremely musical treble boost with a vintage feel ! Great shimmer, never harsh !” Nir Felder
” The Rooster is an incredible ! It is the smoothest treble booster I’ve heard. Between the three settings, it is possible to get the original Rangemaster as well as Hornsby-Skewes tones. When pushing an amp, it’s my favorite color. More than just hearing the note, you can actually “Feel” it coming through the amp.” Ricky Z.
– 9v Boss-type power supply (tip negative): *Caution : this circuit uses positive ground. Therefore you cannot connect this pedal to any type of chained power supply linked with other common DC-powered pedals, unless the power supply unit features separate isolated DC outputs, into which you can plug the Rooster
– The 3rd option is to use a 9v chained power supply (eg 1spot), but you will need the “Diago” isolator adaptor.
