BJFe Universal Reverb V2 / Capitalist Death Cult Actual G*ddamned Springs

 Heavily modified revebr unit by BJFe, treated by Chris Stelloh.

 

A couple of the tweaks are from Björn - in particular, the 2k2 resistor from the source of Q1 to ground. Lowering that value fixes a volume drop that can happen when the 50k dwell pot is maxed. I replaced the second dwell pot with a 10 ohm fixed resistor, so that it is almost at maximum. I also added a flat-mids BMP tone control and BC337 recovery stage that sounds really great paired with this circuit. Using a PN3269a in Q2 can squeal with feedback (a GOOD thing in my world) so dialing in the 10k output trimpot is a necessary step. It is possible to set it so that it only howls when the dwell+mix are turned to maximum. The charge pump is something I redrew from an old tagboard layout. The 555 doubler puts out 30mA of current which this verb circuit needs most of (the schematic says it draws around 20mA, and that was before I added the extra transistor) no matter what voltage you are running it at.

One Control / BJF Anodized Brown Distortion 4K

 So....I'm back. Decided to take screen detox for a while.The backlog of layouts is quite big at the moment so you can expect plenty of them the next coming days. 

I'll wil go through the blog comments for verifications but I'm sure I will miss some so don't hesitate to give a shout out if there is something I've missed...

First out is One Control Anodized Brown Distortion, Björn Juhl's take on a "Brown-Sound-In-A-Box". As usual there are some intereting design quirks here, most notable being the J FET gyrator ( which runs on 5v, hence the voltage regulator) for the Mid control and the RC filter in parallel with the hard clipping section. The schematic can be found HERE

BJFe Emerald Green Overdrive

 Four resistor value changes and an added resistor transforms an Emerald Green Distortion to an Emerald Green Overdrive....

BJFe Heavy Swede

 Now this is an interesting take on the Boss HM-2 circuit...

The schematic speaks for itself.

PedalPCB Mojito Overdrive Deluxe

 Chuck D. Bones take on one of Björn Juhl's designs, a hot rodded Honey Bee. Lots of tweaks all over the place so it probably differ quite a bit compared to the original circuit. I subbed the hard to source clipping diodes for NPN transistors to match the voltage drop and knee. Regular 1N4148s will work but they have a slightly lower voltage drop.

Mad Professor Ruby Red Booster

For now, only the booster/overdrive section, might add a separate board for the switchcable bypass buffer later on... 2N5952s is getting really scarce but 2N5457s or 2N5458s is usually a good sub. Just mind the orientation!

Mad Professor Blueberry Bass Overdrive

 This is basically a higher gain version of BJFE Blueberry Bass OD since it has an added pre amp stage (Q1). Note that originals had the now obsolete BF244A transistors with DGS pinouts. I changed the pinouts for more accesible transistors. 2N5457s should bias up fine and sound good.
