Tools, Tones and Toys for Guitarists
Starting the week out with an early version of the Tone Pump from Barber. It’s very similar to the Silver LTD with a few value changes and a simplified tone control. Here’s the schematic for reference and you can use the Barber Silver LTD drilling template. I believe if you put two of these in … Read more
Here’s YAFF (yet another Fuzz Face) for Fuzz Friday. This is the basic circuit for many Lovepedal variations of the classic fuzz using both germanium and silicon transistors. If using PNP transistors whether germanium or silicon, be sure to flip the the polarized components, etc. Here’s the schematic the layout is based on.
Here’s the Hot Tubes overdrive from Electro Harmonix. It’s based around a 4049 hex inverter chip (like a Red Llama) with a dual op amp pushing it. Original units from the 70s had buffered bypass and a direct out jack. I guess they needed something to fill up those massive enclosures EHX used back in … Read more
Another tube booster/overdrive created by frequency central over at FSB, schematic. What does it do? Well it does clean boost with the Gain set at minimum, flick on the Dirt switch and you get some nice diode clipping too. Turn up the Gain and you’e into overdrive territory with diode clipping, flick the Dirt switch … Read more
Another submini tube based booster/overdrive pedal created by himister over at FSB, schematic. Make sure you are rated at least 25V due to the increased voltage from the rectifier. An additional mod you can do is replace the trimmer with a 250k pot so you can control the distortion produced by the tube on the … Read more
A real nice booster/overdrive that’s basically has a submini tube that replaced the transistor create by frequency central over at DIYSB, schematic. Make sure you are rated at least 25V due to the pedal running +12V. Version 1: Symmetrical Clipping Diodes Version 2: Asymmetrical Clipping Diodes
Here’s a nice little MOSFET-based clean boost that EQD used to make. It’s actually pretty similar to the Lovepedal Delux 60. Here’s the schematic for reference.
For Fuzz Friday here’s another take on the classic Colorsound One-Knob Fuzz by Emanating Fist Electronics (a sister company of D*A*M). It’s fairly similar to the D*A*M Meathead, but with a few value changes. Here’s the schematic: Note that in earlier versions of this circuit, R4 is replaced by a 20k trim pot. So the … Read more
Here’s a cool variation of a buffer-less Tube Screamer with a BMP-style tone stack in the middle. There are also several trimmers that control the Presence, Bass, and Mids, and they’d be pretty easy to wire off board if you wanted the controls externally. If you want to go with the stock configuration, it should … Read more
There have been a few different iterations of the Soul Preacher. This one follows the version that isn’t based around an OTA chip (much like a DynaComp), but is rather much closer to an Orange Squeezer. The original used a buffered bypass, and I’ve included an extra pad for the buffer out if you want … Read more
