Ampeg Scrambler

Here’s another oddball fuzz circuit. The Ampeg Scrambler is a very unique sounding fuzz pedal that I thought I would build, even though I really have very little use for it. Its sounds range from a mild mis-biased overdrive to a really bad (in a good way) squawk to 8-bit octave up sounds.

Here’s the vero layout I used. Thanks Sabrotone!

The pedal features just two controls. One for Blend and one for Texture. The blend allows you to mix the “wet” signal with your guitar’s clean tone, and the texture simplies adds more insanity to the sound. I thought about adding a master volume to this pedal, but then decided against it. My favourite sound is using a neck pickup (with tone on zero) and playing higher up on the fretboard. This allows the octave up sound to really shine through, and sounds great with a dash of delay and reverb.

For the paint I used a combination of anodized automotive paint, and a wire brush attachment on my dremel to get a bit of a flamed maple look to the enclosure. Once again, I created the artwork using GIMP. Here’s how she turned out.

I thought about using the Ampeg logo originally, but I like the way the pedal turned out.

Bazz Fuss (For The Elwins)

Here’s one of the easiest fuzz circuits you can build. This simple circuit contains 5 parts yet sounds great on both fuzz and guitar. I built this pedal for one of my favourite bands, The Elwins. They’re a great Canadian indie rock band from Newmarket(ish), Ontario. I’ve been lucky to share the stage with these boys several times, and they always put on a great show. Here’s how it turned out.

A Battery clip?? Gasp!

)If you check out this webpage Bazz Fuss Fun, you’ll see that there are a few different variations on the circuit. As this pedal would be used for mostly bass, I decided to go with Revision 3. This version features a huge input cap (4.7 uf) and a single Darlington transistor (MPSA13. Here’s a layout for those interested.

Please note the v.3 that I built uses a MPSA13 transistor, NOT a 2N3904 (too gated for my tastes).

I also added a very large electro cap (47 uf) across the power rails. This helps filter out ripple from the power supply (or so I’ve been told), and helps out a bit when the battery starts to die. However, since it’s such a simple circuit I imagine a 9V battery will last a very long time.

I couldn’t decide on what colour LED to use, so I placed several in a bag and chose a random one. We ended up with pink, which oddly enough, looks pretty good on this pedal.

And there you have it. It’s a great first build, and great for modding. Enjoy!

Thing-A-Ma-Bob (Atari/Nintendo/Gated Fuzz)

When I first got into pedal building this was one of the first builds I ever made. To be honest, it’s the perfect first build. It has a very low parts count, will fit in a tiny enclosure, and doesn’t require any “mojo” parts that will cost you an arm and a leg. Here’s the vero layout I used (Thanks to FUZZZZzzzz from DIYStompboxes/FSB.org for creating this circuit and sharing the layout)

Thing-A-Ma-Bob Vero LayoutUpon first building this pedal the first thing that I noticed is that it is LOUD. I added a volume control to somewhat “tame” this pedal. I did this by simply adding a 100KA pot to the end of the circuit. Lug 3 connects to OUT, lug 2 to output (on the footswitch) and lug 1 goes to ground.

You’ll have no trouble fitting this board into a 1590B enclosure. Once again I chose not to add a battery snap (no use for it anyways) and you can see how small the circuit actually is.

It sounds much like an old Nintendo system. It’s gated, dirty, and very “8-Bit”. The one knob acts as a gate. You can have the pedal set wide open and you’ll get oscillating noise but as you turn it up it’ll gate the sound, making it sound sputtery or like a fuzz face with a dying battery. For such a simple build it has some very unique sounds that you wouldn’t be able to get out of other fuzz pedals. It’s not polite sounding, but be warned if you use it at a gig people will ask you “what pedal is that??!?”
