My GAS Range (RangeMaster) pedal

Ok, I'm finally done with this thing. Thank God. Pedals are a pain
in the *** to build.

But here it is, my GAS Range pedal, based on the Dallas Arbiter
RangeMaster circuit. I used the schematic found on this website:

http://www.boardsprep.com/mp3/treble_boosters.htm

In place of the OC44 or NKT275 transistors suggested on the schematic,
I used an NTE158 Germanium transistor because it was easy to get hold
of. And in place of the .0068uf input cap, I used a .01uf, and a
..005uf to come up with .015uf. I used the suggested .10uf output cap,
and it's wired PTP between the pot, and the DPDT Carling stomp switch.

The jacks are SwitchCraft, and those were wired into the enclosure
using cloth covered solid core wire because I like using it, and I
want those wires to stay put. The wires that need to flex are
recycled stranded wire from a car stereo wiring harness. The cloth
wire, Carling stomp switch, and the jacks are from Lord Valve, and
most of the rest is from PartsExpress.

I like that polished aluminum look, but hate polishing it:

This is the underside of the perf board:

I put that one polarized cap on the underside of the perfboard to keep
down the clutter.

Don't want to do this again anytime soon, but the pedal's a blast to
play through and gives me a lot more gain than I need (I have to run
it at less than 50%). It's like a boost pedal with an attitude. I
like it a lot better than the MXR MicroAmp and the EH LPB-1.

Nice pedal, but it's a combination of a good circuit design, and a lot
of blind luck selecting parts.
