PLL and Ringstinger

[PMowdes]

Hey Y'all

Thought you might be interested in some recent projects I've been doing with Dino.

First up is the lovetone ring stinger.  This one has had me pulling my hair out for months, finally traced the issue to a mis-orientated diode on the daughter board.



and the other is a Schumann PLL clone with onboard controls.  We had to rearrange this a few times to make the knobs fit the enclosure but what an awesome effect, the fuzz along is really nice, especially on Bass



We are about half way through the lovetone builds (just the flanger and cheese source to go) and we have pcb's for all of the schumann builds except the F-loop (which is almost impossible to find)

Holy shit the PLL is a much weirder effect than I expected it to be. But you're right, that fuzz sounds great, I wonder if it could be done as a standalone build?

[PMowdes]

I think the square wave fuzz was isolated and built as a standalone by someone over on DIY, I'll have a look over the schematic and see how easy it is.

This works, replace ground connections with half supply vref. I used a 100kA preamp pot with a 1k.

[PMowdes]

Thanks, I think i'll breadboard it and perhaps knock up a pcb

[Addy Bart]

Cool stuff. Will PCBs for the Ringstinger be available to buy?

[PMowdes]

Yes, we have ordered a small stock, they'll be available over on www.deadendfx.com soon.

[Addy Bart]

Excellent

[Silver Blues]

That's the fuzz component? Huh ok, seems simple enough. I'll have to give this one a more thorough look, I'd definitely be interested in it.

Just ordered my PLL boards! Get em while they’re hot

Gonna try to order parts I need for that and a couple other things tomorrow

[PMowdes]

Thanks Travis, much appreciated.  I'm surprised that the Ludwig Phase II boards haven't sold faster :)

[Travis]

The Ludwig is insane and I’m blown away that you did that one. I just haven’t heard any clips of that one that made me GAS.

So excited about the PLL though. I’ve wanted to build that since it was traced years ago, but was waiting for a PCB like yours to come out.

Can I use the regular board mounted 16mm alphas (tayda) and regular solder lug mini toggle switches? Wondering if I need to order any long legs or long shafts or other special items for the board mounted stuff.

[PMowdes]

I cant take credit for the Ludwig, that was something Dino did with RG Keen et al.  We just got the boards fabb'd.

As for the PLL it has been design for standard components. 16mm pots and solder lug switches etc

A word of warning though:  Boxing it is a bit of a bitch.  

I soldered the switches to the board but not the pots.  I drilled the enclosure and fitted all of the pots onto the board (BUT DO NOT SOLDER).  Fit the board + pots to the enclosure and tighten the nuts,  only then once all the pots were in place did I solder them.  LEDs I fitted last.

I don't want to teach you to suck eggs, I'm sure you have your methods but I was nearly in tears the first time I tried to box mine.

Dino suggested to me that I use solder lug pots and make my own "legs" with solid core wire, it works a treat and gives a little more flexibility than the right angle alpha pots.

Gimme a shout if you need any more help

[Travis]

Lol I know what you mean about how tricky it can be to get everything to line up and go into the enclosure. It’s not like you can reach under the board to hold the pot while you tighten it or make a little adjustment.

I think I might be lazy and mount the pots and switches to the lid of the enclosure, so that I can get my fingers under the board when I’m assembling all of that. That should make boxing it infinitely easier even though it isn’t the most aesthetically pleasing option. It might have kindof a cool industrial vibe.

glad i ordered my pll board when i did. doesn't look like they lasted long lol can't wait to get the ringstinger too.

[Travis]

Congrats on selling out of those so fast Phil!! Great work buddy

[BetterOffShred]

I have a build thread over on ILF.. I drilled a piece of plexi, mounted everything and soldered it, then drilled my enclosure to match.. it all dropped right in  :)

[Travis]

Yeah that was pretty much my first idea (though I’d drill through the template and enclosure at the same time).

I changed my mind because it is not ideal to tighten the nuts on the pots and switches while they are soldered to the board. I thought about doing them finger-tight with a dab of loctite but I think mounting everything on the lid makes more sense to me

Thanks Travis.  We have some more in transit so they should be back in stock soon.  I can't wait for Dino to verify the Tresonator

[Shaggy45]

Looks like the pll boards are back in stock and the ring stinger is available now. just placed my order for the ring stinger
