Plosive May Treble Booster

Plosive

treb·le boost·er - ('tre-b&l 'bü-st&r) noun
a: an auxiliary device used for pushing a tube amp into rich sustaining saturation. See also (electric guitar, rock or groupies).

This is the treble booster used by Brian May during the mid '70's. Inspired by the Rangemaster and Vox Boosters of the day, this booster was designed to produce a more aggressive voicing. This booster uses a silicon transistor instead of the Rangemaster's germanium transistor, and the result is not a clean, transparent booster (which is a good thing). At high gain levels, a fair amount of grit is added, producing a very rich distortion tone when combined with a tube amp.

The original design was intended to be always on and thus lacked a stomp switch. It also had a fixed EQ curve and lacked volume control (he used the guitar's volume instead). While this stock arrangement sounds excellent as is, I felt that the modern guitarist would demand more flexibility, so I've added the following enhancements.

  • Gain - Not to be confused with the more typical volume control found on other boosters which merely turns down an already distorted signal, the gain control allows you to clean up the signal at lower volume levels. The stock setting is all the way up, of course.
  • Tone - Nine-way rotary tone selector. 12 o'clock is the stock setting with four brighter settings and four darker settings. This turns a one trick pony into a tone machine, and allows you to voice the effect to mesh with your guitar and amp.

Other features include true bypass switching, LED Indicator, 9V battery and 2.1mm DC jack. DC jack is center negative and requires a regulated supply. Dimensions - 4.7" x 2.4" x 1.6". Shipping weight roughly 1 pound.
