Ok. This has absolutely nothing in common with all the other 14 different versions of Big Muff Pi. As the effect has two individual sides, one for distortion and other for overdrive, i thought i’d draw the sides as a separate layouts. You can, of course, use one 16 x 31 board to have both … Read more
I was cleaning up my layout folders and noticed that i had not posted this one up. It’s a slightly modified Machine. First of all, the second driver stage has a gain control now, per the Madbean “Macheen” schematic. Also, i found that using Si diodes and a smaller value for the Limit pot made … Read more
With 4 internal trimmers this was a pain to keep 1590B friendly. As it sits it’s 22 columns wide and so will just fit in if you file the sides down a bit (and insulate the side of the box next to the board with electrician tape or similar to avoid shorts). It will however … Read more
..and i’m back. Been a one hell of a month with kazillion things going on… Here’s something quite cool i ran into. Haven’t had time to build it yet myself, but it is quite high on the priority list. According to the information provided with the schematic (here), this seems like a highly tweakable crossover … Read more
On a roll now :o) Info from the manufacture about his original Jerkulator copy: Short for Total Harmonic Distortion + Noise. The THD+N is a Lo-Fi Fuzz with with Harmonic Distortion measurement is excess of 80% which are sweepable between even order and odd order harmonic distortion.
It’s christmas eve already. Ho ho ho for all you builders out there! We seem to have very few effects with buffered bypass, so i think i found a suitable one. The Peavey HFD-2 Hotfoot Distortion. It’s more or less 1:1 with a Rat, but with added JFET input buffer which also takes care of … Read more
BBE’s take on one of the classics. Once again, the power supply filter cap is probably an overkill, so use 47µ, 100µ or 220µ instead of the 1000µ.
I wasn’t aware that BBE would release nice, simple designs with all through-hole components for good bargain prices. Funny how all the units on eBay are priced about a double of the original unit as a new… The input cap (4n7) could be upped to at least 22n and there are other things one could … Read more
Now, there is only couple of small changes to the output buffer and volume control when compared to the original Rat. The volume control looks like it could give you some trouble with the output level. If it does, just snip the 10K resistor from volume 3 to ground. I would personally use linear taper … Read more
Been waiting a long time to post this one up. Yup. It is 1:1 with Rocktek DIR-01 Distortion. The schematic i found was missing a couple of values, so instead of guessing i got myself an original and checked them. My original just happens to be this beautiful japanese plastic thing. It doesn’t quite reach … Read more
