David A Mains take on a tonebender that should have been released before Tonebender Mk. 1…:-p
Month: November 2020
D*A*M: Super Bee SB-68, 0.15″ Vero (incomplete trace)
The D*A*M Super Bee SB-68 was mentioned as something that had not been traced yet, which made me curious. I looked at a few photos and found that there are two versions. One with OC82s and one with OC78s. Some very slight differences, but otherwise, a MKII Tone Bender cramped onto a smaller board to fit the … Read more
Electro Harmonix Small Stone V3
There was a an incorrect value in the factory schematic. It is now corrected and the layout is verified by slammer88.
Electro Harmonix Pulsar
A modified layout for the old EHX Pulsar which is infamous for its LFO ticking bleedtrough. There is two mods that hopefully can solve it. First, an op amp input buffer and second the more common mod; separating the power with a small value resistor between the amplifier and the LFO section. LFO section also … Read more
D*A*M: Meathead M-27
It’s a silicon Fuzz Face with an input cap blend – the D*A*M Meathead M-27, or the Meathead Deluxe. I copied the D*A*M layout from photos on Stompboxes UK and the usual pics on Reverb. Strangely, the same issue I had on another layout – in all photos, the yellows on resistors looked green… … Read more
COLORSOUND: Fuzz Box
They don’t come much more straightforward than this – said to be a Dick Denney design, the Colorsound Fuzz Box is a one-knob silicon fuzz face with a couple of value tweaks, but other than that, you know what you’re getting here. This circuit is also found in the Vox V1141 Super Beatle solid state amplifier. … Read more
Zzoyds Black Velvet Fuzz
Zzoyds modified Dirty Boots by Apocalypse Audio. An extra germanium pre amp stage has been added to convert it from an overdrive into a fuzz. MP38’s is fairly low gain NPN Ge so it can be subbed with 2N1302/2N1304, OC140, 104NU71 etc.
D*A*M: Fuzz Sound FS-77, Tag Board Layout
I couldn’t find a layout for the FS-77 anywhere, but I did find some photos online, so I decided to try and trace it back in November 2020. I thought I had it, but when I looked at it again recently, I noticed the input didn’t look right. The caps were the wrong way around for … Read more
VFE Choral Reef Analog Chorus
Great sounding chorus which is based on EHX Small Clone but with much more tweakability. Note that the swithing board is not included for this layout so the voltage reference components (8,2k, 10k and 47uF) istaken from the switching board into this layout. Schematic and info HERE
