Members guitarpreston Posted January 10, 2012 Members Share Posted January 10, 2012 just acquired one of these from a family member. pots are filthy and so are switches etc. been sitting in the back room for 20+ years. what can you guys tell me about it?

Members Reauchambeau Posted January 10, 2012 Members Share Posted January 10, 2012 if it's wat I think it is, it's probably an Appolo labled Shin Ei Fuzz Wah. it has the coveted Super Fuzz circuit in it, should sound killer. does it have two knobs and a slider switch on the side?

Members guitarpreston Posted January 10, 2012 Author Members Share Posted January 10, 2012 yes it does, well actually on the front (or what i would consider the front). i need to give it some more attention with some contact cleaner and get the pots and switches cleaned up Link to comment Share on other sites More sharing options...
Members guitarpreston Posted January 10, 2012 Author Members Share Posted January 10, 2012 im confused on how the switches work. when i click down with my toe it turns off completely as in no signal comes through. the only wah i have used before was a crybaby and when i do that it turns the effect off and everything sounds normal. is that right or is my switch messed up?

Members Reauchambeau Posted January 11, 2012 Members Share Posted January 11, 2012 the switch should work like you think it should for the wah, there should be a second switch to turn the fuzz on and off. on the slider switch does it have position I and position II? if you open it up take a look and see if it says "Shin ei" on the circuit board.

Members guitarpreston Posted January 11, 2012 Author Members Share Posted January 11, 2012 yea it doesnt say shin ei on the board...but you have described it right...here it is Link to comment Share on other sites More sharing options...
Members onyxrhino Posted January 11, 2012 Members Share Posted January 11, 2012 ^^^yeah, that's a Shin Ei Fuzz Wah all right. Had one a couple years back. Loved the fuzz tone. Wasn't keen on the volume drop, but it's still a great pedal. Congrats! Link to comment Share on other sites More sharing options...
Members guitarpreston Posted January 11, 2012 Author Members Share Posted January 11, 2012 I have to do some work on her. Probably replace switches and pots... Link to comment Share on other sites More sharing options...
Members amp_surgeon Posted January 11, 2012 Members Share Posted January 11, 2012 Shin-ei usually didn't mark the circuit board in any way, other than maybe a part number in the copper on the bottom. They usually stamped their logo on the inside of the base plate, though. Anyway, that doesn't look like a Shin-ei circuit board. Shin-ei's boards were usually very tidy, with all of the wire pads along one side of the PCB. The Shin-ei Fuzz Wah was also an 8 transistor circuit, with 6 transistors in the conventional FY-6/Super-Fuzz configuration, and 2 transistors in the wah circuit. That PCB has a total of six transistors. It might be similar to the Ibanez version of the Shin-ei Fuzz Wah. That version used only five transistors in the fuzz section, replacing the 2 transistor stabilized bias preamp with a single FET preamp. It had one transistor in the wah circuit. Not quite as severe as the Shin-ei fuzz circuit, but it cleans up a lot more when you back off the guitar volume. The PCB layout doesn't look like the Ibanez layout, but it could still be the same basic circuit based on the number of transistors. Anyway, I can see the bypass path from the input jack, through the fuzz switch, through the wah switch, and to the output jack. If you're losing signal when you kick off the wah then look at the bypass wiring on the wah switch (difficult see in the pic because it's behind the white wire) or check the switch with an ohmmeter. Also, looks like they put the battery interlock on the output jack instead of the input jack. They did the same thing with a lot of the FY-2's.

Members guitarpreston Posted January 11, 2012 Author Members Share Posted January 11, 2012 Ah glad you commented I was going to try and get in touch with you tomorrow. Didn't know you were on here. I don't really know for sure what it is. Sticker on the base plate said Japan. It will take quite a bit of work to get going and a used crybaby will be on my door tomorrow so this jewels project might be pushed to a later date. I don't use fuzz a whole lot I just wanted to mess with it a bit. Link to comment Share on other sites More sharing options...
