DOD FX15 Swell Pedal

Requested and verified by AlexS

Original is a buffered effect with input and output connections wired straight to input and output jacks. But you can add a bypass switch, just connect input and output connections to the switch.

Updated layout 200514. Original schematic had a few bugs. Layout corrected with 47pF cap and flipped 2N3907A transistor.

DOD Death Metal Eq

Got a request for this one a while ago. Looks like a more versitale alternative to Boss HM2 eq. original has transistor gyrators but I went with op amps for less space and smaller parts count.

 Here is demo video by MTK comparing them through a Revv G4 clone.

Covid-19 update

Hi there!. Hope everyone is ok out there during these strange times.
Just wanted say that due to covid-19 I got lots to work to do and simply don't have the time and mostly of the time I don't have access to the blog. I will post at least one new layout a week and comments will be answered but within a few days.

Hopefully this thing is getting settled down soon.
Stay safe and take care.

Anderton Super Tone Control

Epider Sound Heavy Metal

An old fuzz/distortion from Brazil produced in late 70's to early 80's. Has an interesting gain control which is using diodes to achieve gate and/or cross over distortion.

Gyrator Wah Wah

Been fashinated by gyrator tonestacks for a while and when I saw this wah circuit by Olivier Jambois I had to give it a go. Sounds very good and powerful and it is loud! Schematic, a nice writeup and soundclips HERE.

Works equally well as a standalone bandpass filter pedal but I recommend to change Wah pot to linear taper since most of the action is at the end of the rotation.
