JHS Treblebooster

Stock JHS Treblebooster in an amp top box like the original. Uses a silicon 2n4061 transistor.

Treblebooster

Point to point 1960's style Treblebooster.

Based on the JHS Treblebooster but with some modifications to the circuit.

Sold to Matt in the USA.

Rangemaster with input capacitor blend control

Rangemaster Treble Booster with added input capacitor blend, goes from stock treble boost to a more mid boost/overdrive. For sale on Ebay here.

Rangemaster

Rangemaster for Craig in the USA. Stock circuit but with an added input capacitor blend control, lets you go from trebleboost to a more full range boost. Mullard OC44 transistor and a eye catching orange case!

Russian Booster

A booster based around the Russian GT308 germanium transistor, more info here. Supposed to be for Bass guitar but sounds good on guitar also. Cuts bass frequencies, and boosts some high frequencies. Some frequency info from the linked thread above - 10 Hz: +2dB, 63 Hz: 0 dB, 100 Hz: -1,6 dB, 200 Hz: -8,5 dB, 350 Hz: -25 dB (notch), 500 Hz: -14 dB, 1000 Hz: -6 dB, 1500 Hz: -3,5 dB, 3000 Hz: -1,5 dB.

Mysteron - Tonebender mk1 + Rangemaster

'Mysteron' for Jem in the UK, who designed the graphics herself.  It's a 2 pedals in 1 'Shatterbox' style unit, featuring a Tonebender mk1, and a Rangemaster.  The mk1 is stock and has OC45, OC72, and OC84 Germanium Transistors.  The Rangemaster has an input capacitor blend control allowing you to go from treble boost to full range boost as you turn the control up, and a highish gain OC72 Transistor.  The wedge style enclosure is a Prism 2 from pedalenclosures.com

EP200 Booster for Bass

EP200 Booster using an ECC82 Tube for Jorn in Norway. Controls are Level and Gain, and the circuit is voiced for Bass Guitar with bigger in/out capacitors than I usually use. The circuit is based loosely on the input section of a Selmer EP200 Echo unit.

Selmer ep200 Echo Boost

Selmer echo boost, blue smooth hammerite finish, handmade turret board, circuit half on board and half on the tube socket, tropical fish input capacitor, 12v dc power only.

Selmer Echo Boost

A Selmer ep200 echo booster with an added gain control for Tim.

Selmer Echo Boost - Better photos!

Noticed there was a smudge on the lens of the camera after taking the last pics of the Selmer Echo Boost so here are some better shots with a clean lense. Soundclip (level only halfway up on booster) here.

Selmer Echo Boost

Finished Booster based on a cross between the Valvecaster and the Selmer Echo 200 input section!  Soundclip to follow.

Treblebooster Soundclip

Soundclip of the Treblebooster I made for myself (a cross between a jhs treblebooster and a Rangemaster, but with blendable input capacitors) here. Later in the clip its the Treblebooster goosing a Tonebender mk1!

12au7 Selmer Echo Boost schematic

I have been toying with the idea of doing a booster based around the input section of an old echo unit for a while,  I found a schematic for a Selmer echo 200 where the input section looked very similar to the Valvecaster (apart from it uses an ecc83 valve rather than a 12au7).  So I made this schematic that uses elements of both circuits.  Have breadboarded it and it sounds good!  Nice tone and overdrives in a pleasant way with chords, also reacts well to playing dynamics.

Zombie Viking Kay Tremolo

Kay Tremolo with Booster for Jon.  He wanted a custom design for this so we tried a few ideas out before coming up with this Zombie Viking theme!

Treblebooster

Made this for myself, it's based on the JHS Treblebooster circuit but has blendable input capacitors, and switchable output capacitors.  The blend control lets you go from trebleboost/basscut, to full range boost, to overdrive when turned all the way up!

Tube Booster

Tube Booster for Brent in the USA.  The input and grounding is all on the tagboard, the main circuit itself soldered directly on to the tube socket.

Tube Booster

Tube Booster for John.

Tube Booster

Tube Booster for Joe.
