Pedal was only released in Japan, and seems like only from 2011-2012.
Name suggests a tonebender, anything but.
Basically a distortion+ with input/output buffers. Standard Maxon JFET switching.
I've built the bootleg / moonshine clone from .
One thing that makes little sense to me is that the volume and blend have very similar effect since the direct signal is not affected by the volume pot. This is confirmed by looking at the schematic at .
* Does anybody have access to a moonshine and confirm that this is indeed the case? I somehow recall Josh Scott mentioning that the moonshine schematics online were wrong.
* How would I modify the pedalPCB schematic to move the volume to...
I just got this on my bench yesterday... already traced! :D
It's a very nice sounding distortion. Lots of gain and a very use-able.
The numbers on the chip are sanded off, but it has the pinout of a common quad opamp. My guess is that it's a TL074; it has the sound I hear from that series.

This is a very good sounding distortion. I wish they were easier to get in the U.S.

reputedly based on the vox UL730 and 7120 amps for revolver/sgt. pepper-era beatles fuzz and more.
I can only guess it's based on this bit, (which appears to be a bit like the fuzzface) with the treble and bass pots merged into a mids pot. It's run on 25v in the amp circuit:

the: sustain pot could be yer typical FF Q2 emitter pot, or maybe adjusting the 220k feedback resistor like the CBread katzenkonig..There also appears to be a gate trimpot on the picture of...
I am looking into modding an opamp big muff with the Pumpkin patch mod by JHS. It adds a mids control and a 3 way gate switch.
The mids control is done, I guess, by altering the 1k2 in the tonestack to 500R and a 1k pot. The gate switch is a mystery to me. I presume it is done by switching between 3 values of fixed resistors. Does anyone know?
Really nice (and _loud_) cascaded TL072 op-amp fuzz w/ what I've found to be an abnormally versatile blended octave stage. It's a ton of fun to play and by far the most flexible boost/overdrive/fuzz pedal I own. While it's remarkable in how loud it'll get, it's also not hard at all to dial in a wide range of more subtle effects.
The pedal uses four slider pots to control overall volume, post-octave gain, texture of the octave effect, and weight of the tone control on the front end. The pedal...
Hello, here's Juliusz from BCS. I thought I'll share some schematics of my discontinued pedals for anyone fancy diy.
Here is GT420 MK1 model (current MK2 version is completely different circuit-wise). It's a LM386 based distortion with a fat silicon Rangemaster in front. What was neat in this particular pedal was hitting 386 not with a boosted signal, but feeding it with already dirty and compressed signal. This caused a rich, powerful distortion with reduced typical farting-out sizzly sound...
I haven't seen this one brought to the table or discussed so I thought I'd mention it. Could it possibly be a HBOD or DRD variant with less high-end filtering?
I was looking for a new OD to push my 100w Plexi Clone and stumbled upon the Scream Honey Overdrive. Unfortunately it is sold out and the price has been over hyped.
Looks to me like it might be an SD-1 clone with some mods and NOS components. A couple of transistors for input & output buffers, 3 diodes for asymmetrical clipping, op amp….. blah blah blah. I just need to sit down and work out the component values.
Hello everyone. I have a 2009 fulltone MDV-2 in for repair and the symptoms were: the chorus setting was full volume, and the vibrato setting was much lower in output. I've seen this complaint on the web before with no solution provided.
Both settings the modulation wasn't strong and got weaker when the rate was maxed.
I have found the cause: fulltone built their pedal wrong.
In this unit at least the chorus/vibrato switch was labeled backwards, and the output mixer had very 'none original'...
I kinda wish I'd tried something easier for my first trace. Does anything look very wrong here?
This looks like a TS (with some mods) with a switch that adds in extra gain on the op amp plus a JFET boost on the back. There's also a separate JFET boost stage on an external footswitch - I've added that as a separate trace below, but it's a duplicate of the output boost on the main pedal. I believe it's also the same circuit in the Flame Boost by Cornerstone.
Here's a trace of a J. Rockett Tim Pierce signature OD that I had on hand. It's a dual pedal with a four-knob OD followed by a MOSFET power amp boost. This PCB is stenciled rev 5 and the pedal dates from 2015. This post is mostly for curiosity's sake since I couldn't find an existing trace. It's a decent but not spectacular pedal and there's nothing innovative inside.

Old Blood Noise Endeavors - Haunt Fuzz v1 tracing. This came from an early pedal with low double-digit serial number in a light blue enclosure.
Notes:
1) Enclosure labels for 'Low' and 'Mode' appear to be reversed. Documentation states that 'mode' switches between two different silicon transistors. I found these transistors are actually connected to the toggle switch labeled 'low'. There is a difference in breakup and gating at each transistor setting. The 'mode' toggle switches between two...
With the money I got from the Vibrostomp I went ahead and got one of these guys because the soundclips were great. Good news the pedal lives up to the clips, it sounds exactly the same as the vibrato on my 214, and has more depth without getting muddy like the Vibrostomp. Great pedal for the price too, solidly built.
Was a little tricky to get all the goop off, it was latex stretchy stuff in two layers. It's an upside-down pcb, which is odd, but functional, and a super simple circuit with only...
Hey! Just got this yesterday. It's a great sounding Range-master derivative, with a lot of control over the sound. More of a dirty boost with a fullness control of sorts (RANGE) than a treble booster, although those sounds are in there. The nasty stuff on the back of the pedal is not Catalinbread's doing, it's my failed attempt at desoldering that jack there. When I got the pedal, it was a clean PCB :)
The schematic is hand-drawn, and it looks kind of funny at the input, so if somebody would...
