Tools, Tones and Toys for Guitarists
Time for some bass distortion. This one’s a RAT with an input buffer and soft clipping instead of hard. Apparently these were built on the same PCB as the Fat Cat and LA Metal. For a drilling template just use the Fat Cat one.
I’ve seen a few people playing around with discrete opamps in classic circuits, and thought I’d give it a go with one of my favorite circuits, the classic MXR Distortion + (or DOD 250, etc.). The typical 741 opamp has been replaced with Joe Davisson’s Diode-Compression Opamp. The 6.8k resistor in the bottom left corner … Read more
Here’s Vertex’s Trainwreck-style pedal. Essentially a modified Ibanez SD-9. BJT input buffer, opamp gain stage, followed by hard clipping, a fixed BMP-style tonestack, and JFET output stage. Schematic over on PedalPCB.
Happy Black Fuzz Friday, everyone! Be sure to check out the store for a bunch of new boards and a 15% off Black Friday sale. Use coupon code “blackfuzzfriday” at checkout. Here’s a cool silicon Buzzaround variant I found browsing DIYSB. Any low hFE transistors should work ok. 2N2222A, 2N2369, MPSA42, etc. Should fit nicely in … Read more
This just got traced by Aion and he was kind enough to share the schematic along with a cool tracing journal on his blog. As to what the SS-3 is, it’s like a beefed up Cornish G-2, which is his take on the Distortion+. The original uses 2, single op amps, but for the sake … Read more
This one was actually pretty easy to knock out after doing the G3. Slightly simpler and with less clipping than the G3, it’s got loads of gain on tap. This also has the same pot layout as the the G3, so just use that drill template.
You guys super pestered me to do this one, so here it is. Now get off my back! 😄 Layout turned out fairly big, but not overly so. It should fit nicely in a 1590BB.
For Fuzz Friday this week I give you the Dusky Electronics Hypatia. It’s based on the Bazz Fuss, but with a whole lot more control added gain stages and buffers. Should fit nicely in a 1590B. Here’s the schematic for reference.
Here’s a simple auto wah circuit with a pretty low parts count I thought was interesting. Not a lot out there on it, but it uses a single CD4049UBE to create an LFO and wah audio path. The depth of the effect is controlled by the LFO. Should fit nicely in a 1590B. Here’s the … Read more
Here’s Keeley’s PT2399-based delay that aims to emulate old tape delays. I think it’s the first delay on the blog with built in modulation. It’s laid out with board mounted pots for a 125B enclosure with top mounted jacks. FYI, the trimmer controls the gain of the input stage.
