RIFT AMPLIFICATION: EL34

RIFT AMPLIFICATION EL34 vero layout v1 cb797e1006a7

It’s a single transistor boost, not unlike an Electra.  This pedal is somewhat infamous in the DIY community for exaggerated claims about what it sounds like – although no one in their right mind would question the quality of the point-to-point work in the enclosure that Rift did.     The Boost switch is normally a foot switch.  … Read more

JOHN HORNBY SKEWES: Selectatone TB2 Treble and Bass Booster, Tag Board Layout

JHS selectatone tb2 tag board layout v1 98bc5b238e14

While on the JHS thing, I noticed this booster and thought it looked interesting.  The output switches between filters to allow for treble and bass boost, unlike most other boosters where it all happens at the input. Very few seem to be around, as I could only find one photo of the internals and one video … Read more

ANALOG MAN: Beano Boost

ANALOG MAN Beano Boost tag board layout v1a 13a898fe84fa

The Analog Man Beano Boost takes the classic Rangemaster treble booster and adds a very useful function — a switched input capacitor that widens the tonal range beyond the original’s treble boost. Because it’s a single-transistor germanium circuit, the choice of transistor does shape the tone and clipping character, especially at higher gain settings.  That … Read more

EARTHQUAKER DEVICES: Bows

AVvXsEhs0jVvGyW2o6Z8U3FP5s1Zvw0iEyAS6JHG7IRydbPDRbTSrNj15ZOtHNk7WsTRP YpwsLxQp25ALtVzt6loG6N8jIchfmBGUuzoEjAi5QFIQmSq7Dykcir9q9cSJipcfWrXkJU 0b6eef4ece0b

The Earthquaker Devices Bows is a straight-up germanium Rangemaster with some modern tweaks.  It uses an NPN transistor and has a switch to swap to a larger input capacitor for a full-range boost. The space above the transistor on this layout allows it to be mounted on its side (bent over 90 degrees), as OC transistors are … Read more

PETE CORNISH: TB-83 Treble Booster, Point to Point Layout

AVvXsEjZjHOP3mXFQ0LNdXwe4jlyLxW vkjQAhAmNzO5e2Ng9qfLNny9uXkoezT1F02GeyDUkp1be L15iT3lxrdqlNXNEASavR85tOHkCjdOTv196rTX1DP00lQ4cc5OJNMzHOPj4JT 5ad934faecdc

I followed a vaguely similar layout to the one pictured at the bottom of the post for the Pete Cornish TB-83 Treble Booster.    This is a straight treble boost using a silicon transistor – it’s going to sound horrible into anything apart from a cranked valve amp, or maybe a valve based pedal.  Given … Read more

DALLAS: Rangemaster, Tag Board Layout

Dallas Rangemaster tag board layout v1a fb8ca688d581

A bit of a classic – well one of the first guitar effects really, the Dallas Rangemaster.  A nice simple one for a quick build using leftover tag board.    In theory there is room to fit the output cap on the board too, but I liked the straight lines of the components.   DALLAS RANGEMASTER TREBLE … Read more

D*A*M: Red Rooster Booster, Tag Board Layout

DAM Red Rooster Booster tag board layout 2fe703e6d468

While I was thinking of what could be made with tag board off-cuts, this popped into my head.  The D*A*M Red Rooster Booster is probably my all-time favourite booster – I’ve only ever made one, and it was so good I stopped there (it was a point-to-point npn version with trimmer). This is a PNP … Read more

D*A*M: Red Rooster Booster, Point to Point Layout

DAM Red Rooster Booster P2P layout 11aa118f11a8

A variation on the classic Rangemaster Treble Booster from D*A*M.  The Red Rooster germanium booster uses a NPN transistor so it can run off a normal power supply, and features a capacitor blend on the input to sweep between treble boost and full range boost. This has a lot of boost on tap – it will crush … Read more
