Tools, Tones and Toys for Guitarists
In honor of it being Pi Day, I thought a Big Muff layout would be appropriate. While not an EHX Muff, the EQD Hoof is a BMP variant. It uses germanium transistors as well as LEDs in place of the typical silicon diodes in the 2 gain stages. It also has a Shift control, which … Read more
The Talons is a great sounding overdrive pedal and is EQD’s take on the Marshall Guv’nor. FSB member Zedsnotdead traced it and requested a layout with board-mounted 9mm pots to fit in a 1590B. As per usual, the pots should be mounted on the solder-side of the board. Watch out for the EQ pots as … Read more
The White Light is based on the MXR Distortion +/DOD 250 circuit, but with some modernization and improvements. There’s an added tone control called “Weight” and the toggle switch adds compression by adding an extra germanium clipping stage. The board is laid out for solder-side mounted right angle PCB pots or you could use long … Read more
This is a great sounding Orange amp emulator by EQD. The EQ controls allow you to boost those frequencies instead of just rolling them off. Lots of big burly Orange tone in this FET based circuit. I’ve laid it out so you can board-mount all 4 pots from the solder-side of the board using right … Read more
Here’s a simple one that should fit nicely in a 1590a. EQD’s take on the Electra Distortion circuit. Instead of having a pot coming off the end of the circuit, the volume is controlled by a pot coming off the emitter of the 2N3904. It’s really more of a gain control than volume and if … Read more
Here’s a good sounding overdrive from Earthquaker Devices. This is for the first incarnation of the Crimson Drive with just level and gain controls. Uses a J201 in a buffer stage and a PNP AC128 in the gain stage. Dirk_Hendrik from FSB traced one and drew this schematic. The power filter section makes me scratch … Read more
30th October 2014 – Put on hold pending investigation :o) Info about the original: The Earthquaker Devices Monarch Overdrive is an FET, all discrete dirt machine that will get you some truly vintage and organic overdrive. The Monarch Overdrive is based on a certain UK hard rock amp’s input stage that shares the same color … Read more
Interesting take on the Muff with LEDs replacing the usual silicon diodes and germanium transistors for Q2 and Q3. Info about the original from the manufacturer: Our flag-ship device! The Hoof Fuzz is a germanium/silicon hybrid fuzz which is based on character of the classic green Russian muff. It is capable of creating everything from … Read more
Info about the original: The Speaker Cranker is an all discrete dirt enhancement device designed to give your signal some grit and a slight boost without drastically changing the character of your tone. It’s perfect for those that don’t like to fiddle with pesky controls yet want to add a little tube-like breakup or enhance … Read more
A couple of the electro caps look to be the wrong way round to me but this is definitely as per the scheme and it was by Dirk and so a trusted source. Info about the original: The EarthQuaker Devices Crimson Drive is an all-analog, dynamic overdrive that uses a germanium transistor and vintage germanium … Read more
