I just found an old, nearly finished layout for the Frantone Lo-Tone Classic Fuzz in my files, so I thought now is as good a time as any to finish it. After the D*A*M Sonic Titan, I thought I would see what else has an LM386, and this popped up. Kind of unusual with the incredibly low input impedance … Read more
This is as close as I could get to the original layout for the D*A*M Sonic Titan. It’s pretty much a JFET smashing the LM386 with level, but in the nicest possible way. I’ve read a 10k level pot can brighten things up a little. Apparently, this was on some of the earlier versions. There’s … Read more
Per request. Note that there is an option to choose between internal trim pot (as in original) or external potoentiometer for the Freq control. Freq switch is external and the MPQ3904 transistor array is replaced with ordinary 2N3904s. Schematic is avaiable HERE.
An interesting high gain overdrive three cascaded mu amp stages with a poweful and flexible eq section Schematic is avaiable HERE. Came out a bit big with eight transistors and an IC so mounted sideways in a BB enclosure might be the best option when housing it…

Another Dunwich trace by evilarsen, AlexS and fuzzhead. I believe this one was made on custom order and/or was a on/off product. However, compoent values varied over time but we added some notes at the bottom of the layout and schematic for the most significant changes that is worth experimenting with: Input capacitors connecting to … Read more
All the details are listed in the previous post – this is a 0.15″ version of the yellow Colorsound Hybrid Tone Bender. I did the previous layout on standard size vero, and after using 0.15″ vero and tag board on a lot of builds recently, it just seems very tiny now, so I did … Read more
Dunwich released a small run of DIY PCBs a few years ago of a modified HM2. There is a few changes from a stock HM2 most noticable the on/off switches for both soft clipping and hard clipping diodes. You may want to experiment with the cap values at one of the gyrators for a more … Read more
Some says this is a HM2 killer. I don’t know about that but it differs enough circuit wise to deserve its own layout. Note that “Hard/Soft” switch is omitted as well as “Output 2” op amp circuit. Factory schematic is a mess so I had to draw up a cleaner … Read more
