Shin Ei 8TR Fuzz Wah

Can't find much info on a description of it, but what I do know is that it a superfuzz  running into a wah. There's literally 1 component value difference in the superfuzz, the rest is straight up identical to the standard superfuzz.

Quick note about the wiring. Just like the Shin Ei 6TR Fuzz Wah I posted the other day, the fuzz comes before the wah, so you'll wire it up according to the dual effect wiring as shown in the offboard wiring tab. You'll notice instead of making this on 1 massive board I opted for 2 separate boards. This will give you more options for placement in an enclosure, by preventing it from being 1 massive board.

Shin Ei 6TR Fuzz Wah

From Retro-Tone Junkie:

This is a very cool and underrated offering from the king of nasty vintage fuzz. This one is Kent branded but has the shin-ei stamp inside. It is widely known that the wah in these is less than desired. This is definitely not a funk machine and you will not channel your inner Hendrix here, but the fuzz really makes up for it. These are 2 transistors short of being an exact superfuzz circuit (TR-8) and in my opinion lie somewhere between the fy-2 and the fy-6. 

It has 2 knobs for volume and fuzz adjust, as well as a fuzz tone selector switch that changes from hard to soft. Very much like the superfuzz it basically goes from a scooped, darker sounding tone (soft) to a cutting midrange sound (hard). It also has 2 stomp switches, one of which will turn the fuzz on or off. And one that works just like a standard wah would, employed by the treadle.

I got this pedal for (what I would call) a steal, and these (non-superfuzz) versions can be had for very cheap on ebay or the forums. They are well worth it in my opinion, even though this version is known for a severe volume drop and doesn't meet unity gain in most situations (very much like the fy-2) it sounds really great. This is the chainsaw fuzz your friends warned you about, to me its like the superfuzz without the octave up. I'm glad I chose not to follow the hype and took a chance on this one.

This is supposedly the fuzz tone used by Jesus and the Mary Chain back in the day on Psychocandy.

Vintage Wah Extravaganza

Well as promised I've taken the and made layouts for 7 of some of the most desirable vintage wahs. You'll notice that they all look damn near identical, and that's because they're all based on the same circuit with some component differences. So instead of doing my usual description for each, I figured I'll let the videos speak for themselves.

One note about the BG-2 that makes it different from all the others. The switch allows it to go from a wah to a volume pedal.

Sekova Big Muff Model 2015

   This is a rare Japanese Big Muff clone made by Shin Ei. It is a clone of a triangle Big Muff, however it has some substantial differences to the triangle Muff layout we have here on the site. The 47n caps in the clipping stages here vs the 1uf caps in the clipping stages of Mark's triangle Muff layout alone should give you a substantially different sound.

   I based this layout on Mark's classic Big Muff template, and included the series polarity protection diode (D1). This diode is not in the original pedal, and you can omit it if you want.
