    Yep that's the one mate. With the cool timber box it came in. There more I think of it, it's bringing back more and more memories of lugging it round to jams and gigs .. so so cool

    Many many moons ago I had the need on my workshop test bench for a multi isolated outlet 9VDC supply. Found one on Fleabay by Viloos for AU$34. It came with leads, 8x9V plus a 12V and 18V outlets, and a 1.5A 18VDC AU plug pack to power it.

    After a few months I found it worked so well on my bench that I bought 2 more for my rig, one for the input jack pedals and one intended for the effects loop pedals thus dispensing any need for a bucket load of 9V batteries. It's not exactly as how things are today as the 2nd supply intended for the effects loop is in my travel case for those times where I want to play away from home. Other than the bright Blue LED's on each output jack when a 9V lead is plugged in I've never had an issue, so I'm reluctant to spend the huge money on upper end 9V distribution gear like the MXR power brick.

    FYI, the 'other 5' on my current 'home board' are a Poly tune 3, TCE Helix, NUX Time core, Catalinbread Echorec and a Behringer NR300 gate..... so many hours of fun, noodling and writing...

    You can't go wrong with a good Fuzz pedal on your pedal board, one of the very first FX pedals made for the electric guitar, way back in the early 60's, and it all started with a faulty Langevin mixer preamp when Marty Robbins was in the studio recording the song "Don't Worry".


    Bit of trivia there for you.

    Gave my red Fuzz Face a test-out to see if it's still working, cause I'm going to use it at an up-and-coming gig at the Nirvana club on Thursday next week, fortunately it is still working perfect.


    It's a surprisingly simple circuit, but what a raw tone it produces, very vintage-sounding, definitely nothing like what you get from plugging straight into an overdriven tube amp, but definitely thick and smooth like a typical Fuzz should be, it does tend to sound a bit woolly in the low end, but I think that's a good thing since it compensates for pickups that tend to be a bit ice-picky in the high end, one thing I will say is that it is very sensitive to how you set the volume control on the guitar, you can get various shades of Fuzz from a slight breakup to full-on psychedelic Fuzz just by turning the volume up or down, it also responds to your picking-dynamics too, pick softly and you get a slight smoky breakup, pick harder and it gets more saturated, if you turn the Fuzz control up to full and pick hard, you get a sort-of compression effect on your pick attack and then a blooming effect when you sustain a note.

    Note: It does tend to sound smoother and better through a tube amp.


    And for those interested in building a Fuzz Face pedal for themselves, I'll post a hand-drawn circuit diagram tomorrow, based on what is currently in my red Jim Dunlop JD-F2 Fuzz Face pedal, and what's on the replacement circuit board I installed, including voltage measurements......stay tuned.
