DREDD 280
Rehoused a DOD 280 build I did some time ago. Upgraded some parts, and did a proper finished enclosure with a decal. Gentle compression at lower settings, or strict as "The Law" at higher settings. Very quiet operation with a LM358. Transistors are 2N3904(220 hfe), and the vactrol is VTL5C2.

Space Fuzz!
Just finished this modified Fuzz Face. It's got a toggle to flip between germanium or silicon transistors, bass cut, pre gain and a bias pot on the outside for easy access. Very versatile!
I opted for no fuzz control since the fuzz face circuit only sounds good fully dimed anyway, and the functionality of the original fuzz control is kind of lame to be honest. The "Gain" feature is a way better option in my opinion. It basically works like the volume control on your guitar. When you roll it back it cleans up for some nice overdrive sounds. The "Body" pot is basically a bass cut. By blending between two caps(3.3uf and 10nF) you get very full or thinner sounding fuzz. The bias pot can also give you different shades of fuzz, and is a very usefull tone shaping tool. Especially cool are the sputtering effect that makes you sound like you're playing through a broken radio speaker!
Also added some power filtering and a protection diode to the circuit. There is also a couple of small caps on one of the transistors to reduce some high pitched noise in silicon mode.
Shielded cable, and a blue indicator LED in a fancy clear lens. Pulldown resistor on the switch for popless operation.
The transistors used are AC127 for the germaniums, and 2N2222/2N3904 combo for the silicons.
AC127 Q1=67hfe/0.08mA leakage
AC127 Q2=125hfe/0.15mA leakage
2N2222 Q1=120hfe
2N3904 Q2=150hfe

Evidence Audio Monorail Bend/Stress Test
So how durable is this stiff cable? How much abuse can it take?
I solder my own patch cables out of these and neutrik jacks, and they are great, but I've been worried they might break if im not careful.
So, to put mr. monorail to the test I cut off a piece of cable and started to do 180 degree bends back and forth over my finger. After reaching one hundred bends I stopped to test continuity. Still works like a charm! I then cut the cable open to see if there was anything visible damage wise. And... not a damn thing. The copper shield and core are pretty much like new.
Just for kicks I cut the core copper wire out and continued to do 180 degree bends. I reached 70 pretty hard bends before the core finally broke.
To sum it all up, the monorail cable is surprisingly tough. The bends done to the cable in this test will almost never happen in real life situations if you take normal care of you patch cables.
No need to worry, rock on!

Batmodrive...!!
Here's one I've been thinking about for a while.. Finally it's done! The Batmodrive! It's the RAT circuit with all the right parts+3x clipping selector switch and the famous "Ruetz mod". The clipping switch has the standard silicon, like the original rats, LEDs like the Turbo RAT, and germaniums like the "You Dirty Rat". Basically three rats in one! The Ruetz mod makes the rat fuller and reduces the gain a little. Very useful to have this one available on a switch.
