Tools, Tones and Toys for Guitarists
Per request.A quite a big revision of this circuit was made a couple of years ago making it a worthwhile addition to the blog. The general topology remains almost the same but lots of component values have been updated. Trimpots is added for easier biasing. Schematic is avaiable HERE.
Traced by Gray Bench Electronics. It is basically a heavilly tweaked hybrid Tonebender Mk. II. I added an anti pop resistor at the input and reoriented the 4,7uF cap. Schematic and teardown video is avaiable HERE.
Just a little one from the Bosstone family. This is said to have been used in MSA Pedal Steel guitars, and it’s basically a slight variation on the Nashville Bosstone circuit. These can be a bit noisy, so really have to watch your wiring and try for quite low gain on Q1. It can … Read more
Traced by evilarsen, AlexS and Marco. evilarsen did the dirty work by building and verifying the board. …and here is evilarsens build.
Yet another modified Bluesbreaker. Did some mods that might be useful. First, Drain, resistors for the J FETs is replaced with trimpots for easy biasing. Two: internal DIP switches is replaced with external toggle switches.. The schematic is avaiable HERE.
This is a little unusual – let’s jump straight to the obvious, the giant capacitors. The Union Tube and Transistor Tourbender is their take on a MKII Tonebender using readily available silicon PNP transistors with a negative ground power supply. Basically invert a PNP circuit and then stabilise it with a lot of capacitance. Watch … Read more
