King Tone Heavyhand Overdrive

While slowly coming back from an eye surgery, I can sit infront of screens again, at least for for short  periods of time, I whipped up a layout for the newly traced Heavyhand. It is basically a tweaked Bluesbreakerwith some extra features and sauce.

Moonn Electronics Big Mess Pi

 Nils from Moon Electronics just released a cool DIY project based on two LM386 audio amps with a russian style clipping stage with tonestack sandwiched in between. And it has a Havoc switch!

Nils own words on it HERE along with build doc and schematic.

I will be offline for a couple of weeks from now on but I'll try to catch up things when I'm back.

Bigger Muff

 Per request. Based on Indigo Ranch Bigger Muff without the high voltage tube section. It is basically based on a Ram's Head variant but with small filter caps and low gain transistors. I added a Mid switch for a bit more versitality.

Maestro MFZT-1 Fuzztain

 Per request. A slightly modernized take on a Moog designed Fuzz/compressor hailing back from the 70s. The signal path remains true to the original but the rotary switch has been removed in favour for a variable fuzz control. And the two compressor settings is now fed through a toggle switch. The CD4007AE IC might be hard to source but it is avaiable at Ebay.

A big thanks to Ian for sending me a couple of these PCB to trace!

This one is already verified by Chris Stelloh, thanks buddy!

Stephen Douglas Leona V1

 Ok, one more layout today. This one traced by Clément who was very generous to send me the schematic. 

Once again, thank you!

 

Arion MDS-1 Distortion

 The cheap plastic casings fools us but Arion did some really good sounding stompboxes in the 80s and 90s. Here is a quite simple distortion unit that is supposed to be a sleeper. Earlier versions had silicon diodes as hard clippers which was switched to red LEDs later on. So I included a diode switch.

Washburn A-D3 Stack in a Box

 A J-FET amp emulator hailing back from the early 80s, quite ahead of its time. Trimpots are included to be able to bias the FETs and the 5,6k inline with the trimpots is reduced to 2,2k to be able to use a wider range of J FETs.

Ibanez BN5 Black Noise

 An old request. This is pretty much a Rat with an active treble control and two fixed eq gyrators making it quite bass heavy. Lots of mods can be done like a diode switch, tweaking the gyrators and the tonestack as well as tweaking the RC filter at the first gainstage.

Death by Audio Interstellar Overdriver Deluxe

 Thanks to Ross to reminding me about this one!

Here we a have a circuit for people that just love offboard wiring. ;-) Also be prepared to use sockets to try out different transistors since this is a "reverse beta" design which can be quite finnicky and be a source of frustration.

And for those who prefer only the second channel and less offboard wiring...
