    Also, I will be posting some more pics of the Axis Fuzz build process this morning along with an audio demo so you can hear what it sounds like, stay tuned.


    I'm also thinking of doing another pedal build in this thread, but it's going to be the Silicon transistor version of the Fuzz Face as used by Jimi Hendrix in the latter part of his career in the Band Of Gipsys.

    Here's a pic of the two transistors soldered in place on the Tagboard, you will notice that I have put some coloured plastic insulation on each of the transistors legs, this prevents any short-circuits and also indicates which leg is which, the Tagboard is now complete and ready for installation in the Aluminium box housing:

    So the next step in the Axis fuzz build process is to mark out all the centres for the mounting holes for the pots, footswitch, Led, and the in/out jacks on the Aluminium box:

    These are for the mounting holes for the in/out jacks.



    All that's needed to be done is to Centre-punch and drill all the holes to the correct size and then the Aluminium box will be ready to be wired-up prior to installing the Tagboard.

    Okay, so I've done all the Centre-punching and have drilled all the mounting holes out to the correct size, all that's left to do is to cut the pot-shafts to size, do all the wiring for the pots, footswitch, and in/out jacks and then install and wire up the Tagboard, after a quick check out with my multimeter it will be ready for trying out with one of my guitars and my Peavey Backstage Plus amp, I'll see if I can do a demo of the pedal a bit later on once I know it's working correctly, for now, here are some more pics of the build process:

    And a quick test-fit to check if everything is going to fit, fortunately it all looks good:

    The blue dots on the pot shields are just to indicate the most anti-clockwise position of the pot-shaft so I can correctly wire the pots up so that they work like they're supposed to, there's nothing worse than having to de-solder the wiring to a pot because it's wired back-to-front, i'm sure some of you have done that at least once, I've been there and done it too.

    Cheers for that, I have just finished building the Axis Fuzz pedal and I'm just going to try it out.



    I've just given it a quick try out......and........she works!!!!


    It actually sounds surprisingly good, considering that it's a Silicon Transistor Fuzz pedal, I've been taking some more pics of the build process so I will post them shortly.

    awesome pedal Doc, the wiring side looks way too technical for me. Where did you get the ally box from, did someone bend the sides into shape for you ? Can't wait to hear the pedal cranking with your new strat build !
    Current Builds and status
    scratch end grain pine tele - first clear coat on !
    JBA-4 - assembled - final tweaks
    Telemonster double scale tele - finish tobacco burst on body and sand neck

    Completed builds
    scratch oak.rose gum Jazzmaster - assembled needs setup
    MK-2 Mosrite - assembled - play in
    Ash tele with Baritone neck - neck pup wiring tweaks and play in

    Cheers Wokka, the Aluminium box was bought from Jaycar Electronics while I was in the process of buying all the bits I needed to build the pedal, the Aluminium box is a Diecast type manufactured by a company called Soanar, I find that these Diecast Aluminium boxes are about the right size to make most FX pedals, I have used quite a few of them to build pedals so far.

    Very cool build. Are all the parts easily bought at a decent electronics store?
    Curious about the 9V battery. Where does it get wired in - it doesn't look like it's connected yet. How long would it last (guess it depends on how much you play) - wouldn't want to have to replace those all the time, especially if you have a bunch of pedals.

    cool Doc so it has a base plate to screw into the box ?

    have you worked out the total cost of all the parts Doc ? be interesting to compare to the cost of a pre-made Axis pedal

    @ Peter think the trick to pedals with 9V batteries is to make sure the input jack is unplugged when not in use. I think if left plugged in they drain the battery. Sure the battery would get a fair bit of life if you remembered to do that
