SONIC VI: Silicon MKI Tone Bender

Sonic VI silicon MKI eyelet layout v2A 2765fc4de3aa

The SonicVI silicon MKI Tone Bender is firmly based on the original, with a few additions and some minor changes.   Being silicon based, the transistors do not self-bias, so additional resistors have been added from V- to the base of Q1 & Q3.  The transistors used are early Mullard PNP silicon OC202 which are quite … Read more

SELMER: Buzz Tone, Point to Point Layout

SELMER Buzztone P2P layout v1 0339821cea7f

The Selmer Buzz Tone – three volts of nasty sixties guitar fuzz. I’d strongly recommend reading this first before committing to a build.  If you don’t, disappointment will most likely follow.  Most mid-sixties three transistors fuzzes are notoriously fussy about transistors / biasing.    Plenty of discussion in all of the usual places regarding what works and what doesn’t.   SELMER BUZZ TONE … 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

LOVEPEDAL: Englishman, Point to Point Layout

LOVEPEDAL ENGLISHMAN P2P layout v1 2f972ead6dc5

Another Lovepedal, another Electra Distortion with big marketing claims…     I found this one in my folders from a while back, so I thought I may as well do a quick update and post it incase someone is looking for an easy point to point effect build. LOVEPEDAL ENGLISHMAN – POINT TO POINT LAYOUT

INTERFAX: Harmonic Percolator, Point to Point Layout

INTERFAX Harmonic Percolator point to point layout d2b3f52c2c38

I would recommend breadboarding this prior to committing to solder.  The Interfax Harmonic Percolator is very tweakable, and sometimes takes some adjusting to get it right.   There’s pages on the Harmonic Percolator on DIY Stompboxes. INTERFAX HARMONIC PERCOLATOR – POINT TO POINT LAYOUT
