Madbean Ballast Point Jr. /Little Angel Chorus

 Ok, I guess I'm back from another hiatus. Quite few layout is in the pipeline so things should be much more active from my side.

First out is a DIY classic; Rick Holts Little Angel Chorus with some useful mods by Madbean Pedals.

Boss NF-1 Noise Gate

 Another awesome contribution Chris Stelloh.

 Another 1980's Boss pedal I use a lot, here's the modified layout for the original gray NF-1 Noise Gate, courtesy of Guitar Electronics DIY PCBs in PolanD: SCHEMATIC 

 I reversed the wiring for the decay pot, since it was working backwards from the original. The LM741 IC is being powered by a 1k resistor-limited supply, so I put the LED+ pad on that rail without any additional current limiting resistors, but if you need your status LED to be dimmer, you can add an extra cut at B23 and place a three column CLR from B22 to B24. As far as the trim pots go, I set the "RNG" to max and the "LVL" somewhere in the middle on my build.

 

Boss CS-3 Compressor / Madbean Oracle

 Another great contribution by Chris Stelloh!

 This is a layout drawn from the Madbean Oracle project, which is, essentially the Boss CS-3 compression sustainer. I really like the sound of VCA-driven compressors, especially on sampled drum sounds. This Boss pedal has been around for about 40 years, and the Madbean version makes a few slight modifications to it based on stuff people have done attempting to improve the sound quality and lower the noise. I included a list of part values that are most commonly swapped to make this more bass guitar friendly.

This one is verified and good to go.

Note that the electrolyctic caps have been oriented in the correct direction in the layout.

Mesa Boogie Mk. 1 Preamp

 A verified layout by Sebastian, thanks mate!

In his own words...

 

I forgot about this layout I did ages ago, built up (it works), and never got around to boxing up: a Mesa Boogie Mk.1 preamp. I'm personally partial to pre-gain tone stacks (e.g. '60s Fenders, Orange Graphic MkII), so I was disappointed with the Runoffgroove Uno having its gain control before the tone stack instead of after. So I knocked together the schematic below, which is basically a straight JFET emulation of the actual Mk.1 preamp if you plugged into Input 1 (i.e. the input with the extra gain stage). This gives the user both pre- and post-tone stack gain controls. I added a Marshall-style "treble peaker" bright cap between the input and 2nd gain stages, just for some extra clang, which can be engaged or disengaged with the "TP" switch. After the master volume control, there's a mu-amp output stage to mimic the push-pull amplification of the Boogie's phase inverter.

I used BF245A JFETs just because that's what I have the most of, but I tested it with PN4393s and J201s, and it worked just as well. The gain boost can be either a toggle or stomp switch; as the original boost was operated by footswitch, I opted for that in my build.

This thing's pretty fun. Like actual Boogies, it takes a bit to dial in a great tone—it's absolutely packed with bad tones, LOL—but it can do everything from crystaline Fender cleans to Weezer "blue album" growl to thrash grind. I hope other folks enjoy it!
