- The 1st Circuit used An Op-Amp IC 741, Some PF capacitors And some resistors. Two 100K Variable resistor (is Used ) In Both Circuit. It provides 15dB of Bass and Treble cut and boost with respect to the gain at the mid-frequency of 1000Hz. The output can be coupled to the next stage.
- Modified VOX Treble Booster diagram: The modified circuit diagram is purposed to be used as an overdrive/distortion unit. The input capacitor is changed from 500pF to 0.01 uF (1000pF) or 0.022 uF (2200 pF) to allow more bass in. This usually overloads the booster and causes crunchy distortion.
- Ql is connected as an emitter follower in order to present a high input impedance to the guitar. C2, being a relatively low capacitance, cuts out most of the bass, and C3 with RV1 acts as a simple tone control to cut the treble, and hence the amount of treble boost can be altered.Q2 is a simple preamp to recover signal losses in C2, C3, and RV1.
- As you can see, the Veroboard layout is much easier to follow than trying to read a circuit diagram, kinda like reading guitar tabs when you can't read music. Some of the projects don't even need you to cut any of the tracks. This Brian-May-style treble booster was a very simple circuit to build and works extremely well.
A treble booster is an effects unit used by guitarists to boost volume and especially the high end of their tonal spectrum, and was popular mostly during the 1960s.
Popularized by guitarists such as Tony Iommi,[1]Ritchie Blackmore, Rory Gallagher, Brian May, and Marc Bolan,[2][3] treble boosters were used to overdrive amplifiers (mostly dark sounding, British tube models such as Marshall Bluesbreakers and Vox AC30s) in order to create a more distorted yet focused sound. They came up in the mid-1960s. By the 1980s they had fallen out of use. Guitarists used overdrive pedals instead, in a similar fashion. But the circuit and its derivatives have experienced a great revival in the 21st century, thanks to the many boutique builders who have rediscovered the circuit. While IC-based overdrive pedals remain far more popular than treble boosters, some players prefer the less compressed and more dynamic response of Rangemaster-family boosters.
Treble-Bass Booster: Very like the Orange and Dallas Rangemaster boosters. Armstrong (Dan) Orange Squeezer: A plug-in-the-guitar compressor: Toner transfer package. Dallas/Dallas Arbiter. Rangemaster: A single germanium transistor treble/signal booster to overdrive a tube input. Very sweet sound Technical description of the Dallas Rangemaster.
Dallas Rangemaster[edit]
One of the earliest treble boosters was the Dallas Rangemaster. Unlike most of today's clones, the original Rangemaster was not a pedal, but a box meant to be placed on top of the amplifier. The circuit makes use of a single OC71 or OC44 germanium transistor.

The Rangemaster has also been used extensively by Brian May, Tony Iommi, Marc Bolan, and Rory Gallagher. Tony Iommi's Rangemaster was modified to be full-range. Pluraleyes 3.
Hornby Skewes[edit]
Just like the Dallas Rangemaster, the Hornby Skewes treble booster was an amp-top unit.
While early Hornby Skewes Treble Booster units used a germanium transistor, the later, better-known version features a silicon transistor. Rumours about a JFET version may source from a misread part number.[4]
It's prominently featured on Jethro Tull'sAqualung album.[5]
It was also used by Ritchie Blackmore during the 1960s until 1974, when it was replaced by a modified AIWA tape recorder. Breakdance movies.
Hornby Skewes also made a bass booster[6] and a treble and bass booster, the Hornby Selectatone T.B.2.[7]
Vox[edit]
Vox made a variety of boosters that were meant to be plugged directly into amps or guitars, including the model V806 Treble Booster.[8] Roger McGuinn installed one into his Rickenbacker guitar in the 1960s.[9]
Electro-Harmonix[edit]
Electro-Harmonix used to make treble boosters in two different enclosures. The Screaming Bird was a plug-in device,[10] whereas the Screaming Tree was a foot-pedal.[11] The circuits were supposedly identical. In 2009 the pedal was reissued, bearing the Screaming Bird name.[12]
Colorsound Power Boost[edit]
The Colorsound Power Boost is a treble and bass booster that runs on 18 volts, using two nine-volt batteries. David Gilmour used this orange coloured unit, but is often misunderstood to have used an Orange brand Treble Booster.[13] Other notable users include Gary Moore.[14]
