Deadringer JR. (from a suggestion by Playpunk)
This is the drive side only of the Deadringer2. Some changes were made to the design. The input buffer was dropped and the clipping transistors were changed from IRF510 to 2n7000 (both due to space limitations). The rotary switch for the clipping frequency was changed to a pot a la the Timmy (although the direction was changed so turning it up increases bass rather than decreases it so it works similar to the tone knob). I pushed this one ahead of the other planned releases because it is a good "essential" project and probably the one I will do the full tutorial on (starting that next week).

That booster looks like it would be a quick and easy one to add to the collection.

- Based on the Cornish G2. This is a true-bypass version fitted for the 125B w/ top mounted jacks.
Interesting I'd always heard the g2 was a more straightforward muff copy. I didn't realize there is an extra gain stage after the tone control. I need to start etching.
Isn't the extra stage at the front of the circuit?

Huh, so it is. I had just been reading r.g. Keen's easy mods page about putting a big muff tone control right befor the volume control on a circuit so I figured that's where it was on a muff. I haven't look a a Muff schematic for ages.
Quote from: chuckd666 on July 27, 2016, 11:32:59 PM

It's the buffer that is always present in the G2 design. There is a separate bypass buffer which is the one not included on this project.
The two buffer sections combined with the first BMP stage form a bandpass filter. I forget the exact 3dB down points but it was around 80Hz and 1kHz. I replaced the first three stages with an equivalent opamp-based MFB filter with gain 10 and couldn't tell the difference.

..will the FlimFlam still be useable as intended if i use MN3008...what modifications should be done to at least extend the delay time....i'll be using my 2 MN3005s for a total recall build and still have an MN3008 collecting dust on my drawer...tnx

Yeah that thing is MASSIVE! plus there are 2 add on boards also...
That is just badass Brian thanks! I'll probably buy the pcb if I decide to build one though.
If we're talking about crazy layouts, I'm pretty sure RG Keen did a layout for the Ludwig Phase 2 that is pretty insane. And a vero layout on top of that.

Some are verified but not listed as such. I really need to update that part.
I've verified the Deadringer Jr, Boneyard, and Aquaboy - BL. Super pumped there are more projects added. I've tried the Ankh twice and both failed for me, but never got any further on debugging. Would love to hear if anyone figures this one out.
I'd like to tackle the horn dog and the band wrecker, but I have never tried etching. Maybe I need to drop a line to our resident hat specialist.
I love to etch, so if the status of the projects were updated, it would be nice.
My participation:
I've tried the Zygote, and I ran on 2 issues, one is that the Fuzz Pot is wired backward.
The other was a noise problem at max gain setting, I've never found if it was a problem from my build or from the circuit. I think it's not from the circuit because the problem was that I was hearing radio interference and it was unboxed...

D'oh! I'll fix that pot. Noise could be from being unboxed, also the lighting situation where you are building (certain types of lights can make a lot of noise on unshielded circuits).

Hi Madbean, thanks for all these recent additions!
I wanted to ask you what was your rules for single sided layout? Trace width, clearance, ground plane, I/O placement, etc. I make single sided layout with KiCad and I want to use your type of design as a kind of standard, to be able to share them with everyone here.

Trace width is usually 24mil except if it's really tight then I go down to 20mil. Ground plane is also 24mil width and isolation except when it's tight then I use 16mil width. I set my grid to the same thing for all layouts - 25 mill size with a multiplier of 4. I/O is generally 9v jack on the left and everything else in the middle (using the bypass supply pins in the MBP library). Sometimes it's a better layout to have the jack at the top but it gets a bit harder to route single sided boards that way in some cases.
Thanks!
I hope I'll be able to share some design soon.

2019 version with some additional mods
Quote from: DFX on September 01, 2019, 10:25:54 AM
from my experience with this circuit ive had to put a 100k resistor from the output to ground to avoid switch pop, noticed the schematic doesn't have this.
Pulldown at the output is contained via the volume trimmer.
Been a very long time since there's been an EP release. Here's a simple overdrive I worked up for a DIYSB challenge (https://www.diystompboxes.com/smfforum/index.php?topic=128480.0). Very easy to build. Or, even breadboard (my experience so far with the circuit).

C4 will have the most effect on tone roll off. C3 and C6 will have the most effect on clipping frequency threshold and total low end (resp).
I do plan on working up a variation for bass on this at some point.

What a great guitar sound. Is that the Danno? It veers into almost Chet Atkins electric classical territory.
That demo sounds awesome! The modulation particularly sounds great - sorry if it's been covered in another thread but will that be incorporated in one of the new PT2399 I noticed on the Projects page?

The new mbp project (Degenerator) uses a totally different method for envelope driven modulation. It does require a few more parts but it's really sweet sounding. One small advantage is that it does not require an additional switch to turn off the modulation. So, there's that. But, both a great projects. I've still got the CD2022 on my big breadboard.
Man, I really like the cave dweller, I need to get on that one:

How is that dynamic modulation in the EP CaveDweller working? I feel like I'm missing something obvious, but it's not apparent to me.
Hi.
I built the original Cave Dweller and skipped the Cave Dweller 2015, so I was really happy to see the new 2022 configuration. I hope you don't mind, but I've converted the schematic into a Vero layout for my own nefarious purposes, even though I was doubtful about pushing the voltage limit on the PT2399 above 5v. It works, though.
After building I thought it was a bit dark, so decided to use the various suggestions (change the 100K modulation resistor to 47K, change the cap in the op-amp across pins 13/14 of the PT2399 to 2n2, remove the 22n to ground for brighter repeats) to brighten it up, and I quite like it.
The MPF102's can be hard to source so I was thinking, since it's essentially a unity-buffer in a sort of cathode-follower configuration, the circuit could probably be reconfigured to use a MOSFET (BS170, say) instead, which is a LOT easier to source, but I haven't built that version yet because the pinouts are different and there's another resistor from gate to +9v to add, etc. I've got a Vero for that, too, though, if anyone wants to try it.
If it's OK, @madbean, I can post the Vero layouts, but I don't want to dilute your great work.
I just finished the Cave Dweller 2022. Such a nice delay! I also have the original Cave Dweller. Both are great, but the 2022 is sweeeet.

I had one on by board the whole time I was gigging. It brings the bar band awesome. I keep threatening to do the double one, but it still hasn't happened.
