Re: EHX Chillswitch

I got one in as the 'Engage' switch doesn't function. I found this on the EHX forum / website: Yes, I got some answers. In my case the problem was a broken rotary switch. These were the instructions EHX support gave to me: “A: Check that R22 is making contact and is actually 22K. (In my case this wa...

Re: EHX - Hot tubes Nano

I love all the cmos analyses on your blog! I've been breadboarding a Red Llama/simple TSF clone but adding the 25th anniversary tone control and a switch to change the power rail resistor/voltage going into the 4049. I've managed to squeeze it on an offcut of stripboard but I want to try other cmos...

Re: T.Rex Replica

I got one in as the echo is really faint. Turned out to be a couple of broken SMD caps.

I traced the analog board inside the unit. Enjoy it!

Harley Benton Silly Fuzz [schematic]

I got this pedal quite cheap. It sounds horrible (check the bias voltages on the schematic)

Got it sounding real good by raising the voltage at the collector of Q2 to around 4.8V by placing a 25k trimpot parallel to R5

Re: Ibanez - Overdrive II OD-855

Wow, check it out. Did a search for some new blood on the subject. https://soundgas.com/product/ibanez-od-855-overdrive-ii/ 1978 unit, script logo, no LED germaniums! (That's after version 1 and before version 2, based on above list.) So it looks like the change to germaniums occured in 1978. That ...

Ibanez - Overdrive II OD-855

I had one in for some TLC. I couldn't find any fitting schematics for this one (V1.0, no LED or DC jack)

Enjoy!

Danelectro - Hash Brown flanger

I only traced part of this pedal as I did a rehouse of it for a friend. I hoped the main PCB (the one with the potmeters on it) could work without the big other board, the one with the jacks and the switch. As it did too much I just left that one too in the new enclosure. There is a ribbon cable goi...

MAStex - Lesli Elektro Hamonix Phpse Shifter / Bad Stone clone

No spelling errors were made in the title. This pedal is a Turkish pedal made by the pickup builder MAStex (pickups for Saz and Bouzouki). I got it in as it didn't work anymore. There was some terrible work done on the pedal and, well, everything was connected to everything. And that does'nt work. I...

Re: Voodoo Labs - Tremolo [schematic]

Thanks for the schematic. Let see if I got everything. That H11F3 is about the bypass switching? Can we ignore it in case of true bypass version? Then I see, in the old version picture, two knobs I guess, that has a PULSE / SWELL... switch or something? You can omit the hf section for a normal true...

Re: Snarling Dogs - Black dog [schematic]

Hello, thanks for the schematic. I've to say for future readers that I totally disagree with you and that I really like the Sound of the Black Dog stock without any mods at all. I like it so much, I bought another one as spare so I have 2. I also bought this week the Tweed E Dog, the circuits shoul...

Monarch MTO-22 Tube Driver (also Aria ATO-1, Ken Multi MTO7 and Pick Boy MTO-7)

I once got this pedal for the EQ. I thought it was another Tubescreamer......

Turned out to be a CMOS overdrive pedal
