OK, guys, the Gristleizer is built up and works perfectly as far as I can tell. As Josh mentioned, there is some slight ticking when using really extreme bias settings, but pretty unobjectionable in my opinion.

One question for you: the way I currently have the flashing LED, it would have to be in addition to an on/off LED. That's how I think Josh has his. Is that a problem? I could probably figure out a way to turn the flashing LED on and off with bypass, but I'm hesitant to mess with the PCB right before ordering a big batch of them. I actually think having the flashing LED on all the time is helpful, but I don't know what everyone else thinks.

I need to change a couple things on the silkscreen layer, but other than that I think we're ready to go on the big order.

BTW, this thing is extremely versatile for a relatively simple circuit. Besides the multi-shape trem and VCF, the LFO gets up into audio speeds for nice ring mod/filter ring mod madness. There are also plenty of lofi, distorted sounds to be had (I had heard fears that updating the opamps would kill all the craziness - not something you need to worry about).

I have no problem with the flashing LED being in addition to the bypass indicator, in fact, I prefer it. Do you want to start taking orders now?

Well, I guess so, but keep in mind that it will probably be about 2 weeks before I can start sending out PCBs.

For some reason the PCB house sent me 2 instead of just 1, so I do have one PCB available right now. If anyone wants one right now, you can have it, but it's green (the final ones will be black). $12 plus shipping.

Re: flashing LED-- I don't think you should change the board for this reason. It'd be easy to mod how the LEDs work to whatever your preference is.


Taylor, sorry if you already mentioned this, but what are the rough dimensions of the board again?

Also, I'm definitely in for 2 boards as soon as you start taking payments...lol...I want another one in a non-stompbox format to keep around for synth stuff, and I want to put together a 3rd one so I can do terrible things to it.  icon_twisted

The more I use my first one, the more I love it. I may fiddle around with pot values as well on the new ones--maybe with some fixed resistors--I know currently I'd rather have more usable travel on my bias pot...

I believe it's 3.3" x 2.1". Fits comfortably in a 1590BB.

Yeah, my bias pot has a very narrow area of usability, but I used a log pot instead of linear, so I figured it was because of that. Maybe a reverse log pot would be ideal here.

Well, if you want a green one you can have it right now. Otherwise, It's probably best to wait until the PCBs are in my hands. There's a hurricane headed this way, so who knows if I'll be around in a couple of weeks?  icon_wink

BTW, the optional cap to stop ticking works well. It didn't seem to have a huge impact on the choppiness of the square wave, but a slight difference. It would be easy to make this switchable if you want maximum tweakability.

Yeah, either that or a fixed resistor + lower pot value. Either/or should work.

Ok, I'm going to make the big order unless anyone has any last thoughts...

First things first, Taylor: Get your ass someplace high and dry, and don't solder anything for the next day or so, ok?

Good job, 2 for me please. As I said a few pages up, let me know how and when with the cash, and I'm in Denmark so + European post and while you are at it add on the price of a beer/smoke/few of your favorite caps on me. Kudos for getting this done.

is/are there CV output jack(s), for example with the LFO? If not then I'll try to initiate a mod...not my forte but willing to try, this would be an ideal modulation source for other pedals/synth stuff

That's why I want 2 Smiley

I don't really need CV ins or outs, since I won't be interfacing it with other effects or a synth, but I'm thinking of adding other LFO options--maybe an additional one to allow LFO 1 to modulate LFO 2. or whatever.
