JHS Superbolt clone PCB and the missing JFETs

Hello solderers and pedal maniacs!

Here is my last build: a JHS SuperBolt clone! As you may know, I have already did a clone of this pedal, but I have finally designed a PCB for it!

Here are some pictures:

I used a Supro logo that was laser-cut with some double tape to make the "Supro" sticker. I think it makes a really nice look!

Development Hell: multiple fuzz pedal

Today, I am going to introduce the concept of Development Hell: it is a special place where projects stay when they need a lot of fine tuning before properly work. Unfortunately, I have a few projects that are still burning there, like the one I am going to present today.

It is a multi-fuzz machine! I always felt that a lot of Fuzz are quite a "one trick pony", they have a very characteristic sound that can be modulated by mods, but still sounds "like a fuzz face", "like a big muff"...etc. Moreover, fuzz are usually quite simple circuits, and I find that allowing one spot per fuzz on a pedalboard can quickly be space-inefficient.

So I decided to create a multi fuzz pedal, with no more than 3 different fuzz inside : a germanium Fuzz Face, a Muff Fuzz and a Companion Fuzz, which should provide the 3 main "flavors" of fuzz in this world: a classic warm, soft fuzz face, a "chainsaw", very raspy Companion Fuzz, and a compressed and heavy Muff Fuzz.

On top of that, I added an upper octave generator that allows to combine it with any fuzz, with a potentiometer to adjust the amount of octave. It is based on the Green Ringer circuit, which is a small, but efficient analog octaver circuit.

And of course, I made it fit in a 125B enclosure...

Here it is in its current form:



Tonebender MKIII clone (Aion Electronics Phobos)

Here is my last build: a Tonebender MKIII clone! The tonebender was initially a derivative of the Fuzz Face, a bit closer to an amp distorsion than a fuzz. (read my post about the different types of fuzz) It became quickly famous thanks to a lot of guitarists like Jimmy Page or Jeff Beck.

The MK2 version used two germanium transistors to get fuzzy tones. However, due to the nature of the circuit, the quality of the fuzz was very dependent on the transistor's gain and characteristics, just like in the Fuzz Face. In order to avoid the selection of transistors, the Mk3 version used 3 transistors, so that the quality of the sound is less dependent on the germanium transistors used. Here is my version:

Boss Tap Tempo DIY

Here is my latest build, a very simple tap tempo pedal for a Boss DD7 pedal (or any other pedal with external tap tempo). It is very simple : one mono jack, one momentary SPST! Very easy build, I think it is the perfect build to begin with DIY! Tap tempo is very useful if you play in a band, so I think this is really a great way to improve your beloved DD7 guitar pedal.

I used a Hammond 1590LB enclosure, which is really small. However, I did not centered the momentary switch because of the lack of space.

Other Vemuram Jan Ray variants

Since I designed my own Jan Ray circuit board, I assembled quite a few. The PCB is quite small, so I have made different variants of various sizes and colors, and I though you migh enjoy it. Here are some of them!
