Tools, Tones and Toys for Guitarists
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
The RTO (or Robin Trower Overdrive) from Fulltone is a modified Tube Screamer circuit. The input buffer is removed and the soft clipping stage has an interesting mix of diodes. For a drilling template, use the Cmat Mods Signa.
I got a request for the Fulltone Bassdrive, and upon examining the schematic for it and the Fulldrive, there’s only a few capacitor value changes between the two, which I’ll detail below. All that to say, here’s the Fulldrive 2 Mosfet. It’s a Tube Screamer circuit with some interesting mods on it. Schematic is easily … Read more
I’ve been meaning to redo the OCD with proper board mounted pots, so here it is. It’s a development on the Voodoo Labs Overdrive, with MOSFET clipping and a simple tone control. Fulltone has made a few versions of this with a few minor changes over the years. They’re all mostly the same, but the … Read more
For #fuzzfriday, here’s the Fulltone 70 fuzz. Like the Fulltone 69, the 70 is a tweaked Fuzz Face circuit, following the silicon version. Like the original silicon Fuzz Face it uses BC108 transistors, though others can be used. Q2 should be higher gain than Q1. One of the nice things about the 70 is the … Read more
Happy #fuzzfriday, everybody! The 69 is Fulltone’s take on the classic, late 60s, germanium Fuzz Face circuit. They’ve added a few extra controls to help shape the fuzz. The Bias (or Input as it’s called in the 69 Mk II) pot is a common mod to the Fuzz Face circuit (it’s a trimmer in the … Read more
I stumbled across the schematic for this a while ago and have been meaning to lay it out for a while. It’s Fred Brigg’s souped up version of the Fulltone OCD. Here’s what he had to say about it over on his blog: The “Super OCD” has a few extra controls:– Firstly the “Bass” control … Read more
There are now 4 version of the OCD. The latest has a few guitarist I know wondering what was wrong with the last version, so if you’re looking to go back to the original circuit, this layout is for you. The OCD one of the most respected overdrives out there. Derived from the Voodoo Drive, … Read more
There was some controversy over this pedal from Fulltone as the circuit is practically identical to the Jack Orman Mini-Booster. Fulltone no longer makes this version of the Fat Boost and now makes a 4-control version with an extra FET stage and more EQ controls. Regardless, it’s a great pedal for beefing up your tone. … Read more
Request for vero version. Info about Fulltone’s slightly modified copy of Jack’s Mini-Booster circuit: This magic little box (the size of an MXR phase 45) is for the Purist, whether you’re a Guitarist, a Bassist, whether your thing is Jazz, Rock, Acoustic/Electric, or Heavy Rock. Not a distortion box, the Fat-Boost is a Class A … Read more
