Axis face layout

[projectx102]

I'm building an Axis Face fuzz from Fuzz Central but the files don't include a wiring diagram that includes the pots,jacks and switch.I'm using a DPDT with no led.It's going into a Dunlop Fuzz Face shell.Can someone draw me up a diagram? Thanks a million!

[John Lyons]

I'm pretty sure there is a generic wiring diagram on fuzz central.
If not you can download one from GGG, or tonepad .

Can some one please attempt this for me? I tried John's suggestion and I guess the one I used is not correct.I know someone here must have built one of these.

I can make one for you tomorrow if you upload the schematic.

Here's the link to the schematic.Thanks! http://fuzzcentral.ssguitar.com/axisface.php

The problem with what I have now is that when I plug a cable into the input I get no voltage readings anywhere.When I plug into the output however,I get readings.I'm stumped here and a good wiring scheme would probably fix things.

Also in bypass mode when I turn the knobs up I get a high pitched whine.

[projectx102]

Wow.

Sorry I'm a bit late replying- just got home. 

You want a diagram of the switch/jacks? 

This diagram from General Guitar Gadgets should be of some help.

According to this layout:


Board INPUT and Pin 1 of your "Smooth" pot connect to pad 1
Pin 2 of the "Smooth" pot connects to pad 2
Pin 2 of the "Attack" pot connects to pad 3
The ground wires (Board Grounds in the first diagram), pin 1 of "Attack" pot, and pin 1 of "Level" pot all connect to pin 4
The + side of your battery connects to pin 5
Pin 3 of the "Level" pot connects to pin 6
Pin 3 of the "Attack" pot connects to pin 7

Off the board, follow the guide from GGG for the most part, but instead of connecting the DPDT switch with the board OUTPUT, connect it to  pin 2 of the "Level" pot.


If you have any more problems, post a picture of your layout and I'll have a look at it.

I did all of that and no good.I'm not getting any voltage at the emitter of Q1 but I get voltages at all other pins of the trannies.I eliminated the switch,DC jack,battery snap and transistors as culprits.I've reflowed everything on the board and there are no solder bridges.

[projectx102]

Well this one is going out for the trash.Thanks anyway.

[slacker]

You shouldn't get any voltage on the emitter of Q1 because it's connected to ground so it will be zero volts DC.
What are the voltages on the other transistor pins, or has it gone in the trash already 

[ballooneater]

You did check the pinout of the transistor, right?

[projectx102]

Yes I checked every single part of the circuit and wiring.I swapped out switches,resistors,caps,diodes,transistors(checked the pinouts several times) and it just will not work so it's trash.

[projectx102]

I needed a decent wiring diagram to help me through this because fuzz central doesn't provide it the way GGG does in their layout.It has to be a wiring issue and written descriptions do not help me hence the reason I originally asked someone to possibly draw one up so I can visualize where my mistake is.The signal is passing fine in bypass but nothing when circuit engaged.The readings on the transistors are: Q1: e-0  b-.64  c-1.80    Q2: e-1.11  b-1.80  c-4.53    I'm getting a reading of 0 at the grounds.

Here's a wiring diagram for the board, hope it makes sense



Use this with the GGG wiring diagram posted above and hopefully everything will be fuzzy.

[projectx102]

That's exactly how I had it wired and still no go.

[projectx102]

I posted the voltages at the trannies a couple of posts up.do they look ok?

[slacker]

Your voltages look fine to me. I would eliminate any possibility that it's a wiring problem by disconnecting the switch and just wire the "In" and "Out" straight to the tips of the input and output jacks. If you then get sound it means there's a problem with the switch or the switch wiring. If not then the problem is somewhere on the board.

[projectx102]

I finally got it.It was the switch.I had bought a few of the EH 3PDT's from pedalpartsplus and they are different from the ones I was using.I found a wiring diagram online using the EH switch.Thanks everyone for the help!
