Tools, Tones and Toys for Guitarists
This is currently on hold till I figure out the tone control issue or someone can shed more light on this circuit. Build at your own risk. I stumbled across the schematic for this effect and thought it was another variation of the Marshall Bluesbreaker circuit. But realized it actually predates the Marshall circuit by several … Read more
Here’s an interesting Fuzz Face variation designed by Bjorn for Fuzz Friday. Here’s the schematic for reference. It can also be purchased as a kit from Moody Sounds out of Sweden. Should be an easy fit in a 1590B.
Happy New Year, everyone! Some audiophiles have really gotten into preamps that use discrete opamp—basically using and bunch of individual transistors that make up the internal circuit in an IC. This trend has also made it’s way into the guitar world as well. One of the simpler circuits I’ve seen you can do this with … Read more
This is an adaption of the Fulltone Bassdrive without the boost footswitch, allowing for a smaller enclosure. I got the idea from a comment by Simão on the Fulldrive 2 post, and I though it could prove useful for my fellow bassists. Like the Fulldrive/Bassdrive, it’s modded Tube Screamer with clipping and voicing options with … Read more
This is (or was now I guess) one of the few Run Off Groove designs I haven’t laid out. It’s not a small circuit and I ended up laying it out for a 1590BB so the pots can be board mounted (but it will fit in a smaller enclosure if wire them off board). I … Read more
The originals used a now nearly unobtainable SAD512D chip, but the wizards on FSB converted it to work with an MN3007. Now that those are also hard to get a hold of, I’ve laid this out for an MN 3207–which is almost the same as the 3007, just with a slightly different pinout for power … Read more
This was a request. You could use external pots instead of trimmers. Schematic available here.
The Ashbory bass was first introduced in 1986 and is/was a half scale (18″) fretless travel bass with a piezo pickup and built in preamp. That preamp is essentially a Baxendall tone stack feeding into the volume control, into an op amp based gain stage. I stumbled across the schematic and thought it would be a … Read more
An old circuit that was missing from the main page. There was a layout by Harald Sabro in the forum section but this one should be easier to build. I’ve taken the “Bite” control from Codtone’s Expandra. You can remove it by adding a link between Bite 3 and 2. I’ve also added two more … Read more
I’ve heard that in 1991 former Lell engineer went on to form a new company called Rostex. At least that’s the rumor and i have no other information about the brand or the pedal. You know anything about these (or have a demo clip/video), please do post it in the comment section. For the layout, … Read more
