Tools, Tones and Toys for Guitarists
As requested. I happen to have an original unit in metal enclosure, and to my ears this is definitely one of the greatest Ibanez overdrives. This layout is with your standard transistor pinout and with input buffer omitted. Reason for omitting the buffer is quite obvious… It is big, but should fit in B-box without … Read more
There you go John. We’ll never have enough bass designs… This one is basically a Rat for bass. Thanks to John, this one is now verified. Which also means that the LM7 and FC10 should be safe to build.
The orginal unit uses two 9V batteries and electronic swithing. I removed the latter, but left the supply voltage wanting the 18V. With this, i also left the (possibly) destructive polarity protection method in tact. For the supply, one can use two batteries or add a small daughter board to pump the standard 9V voltage … Read more
Without the pseudo-balanced output and adapted to work as a stompbox. Not really sure if this is worth a build as it is supposed to be not that loud. Simple design with low parts count, so it might be nice thing to experiment on… The pot tapers are not mentioned on the schematic i found, … Read more
I was struggling to get this one 21 columns wide max, so Miro will have to forgive me for the placing the Nature pot wires at different sides of the board. Sorry mate :o) Info about the original: The Model G captures the unique voice and response of an often overlooked brand of amps from … Read more
Pink Jimi Photon’s take on Interfax Harmonic Percolator and Escobedo’s Jerkulator. Read maestro Photon’s complete description on FSB. rock the f**k on!! the vid/audeo is outta sync, too…..arrrrgh who needs LSD?
The first in a line from the MXR Custom Badass design team, the MXR Custom Badass ’78 Distortion is a factory-modded pedal that roars with huge amp stack tones and old school tube amp-like distortion. We took a classic distortion circuit and hot-rodded it to the next level for over-the-top soaring leads and rich, saturated … Read more
Next up in the MXR Custom Badass line is the Modified Overdrive—a classic overdrive circuit with modern modifications for improved performance and versatility. For added flexibility, we’ve added a 100HZ cut and boost control that allows for a more focused EQ when cut, or a beefier tone when boosted. The Bump switch engages an alternate … Read more
Yup. Most of you who know me know that i’ve had more than enough trouble with JFET biasing on some fixed drain resistor designs… This one also has the input cap and pulldown resistor at the input. Already verified by me. I found the best gain to be with drains at ~5V, but now you … Read more
Happened to spot one on ebay for mere 250 usd. A bargain. For this layout, i omitted the buffers and electronic switching. 30K pot value may be hard to source, so one could try 50k pots for all of them. Original unit has 2SC2240BL transistors which are low noise devices with BCE pinout and hFE … Read more
