None of mine have ever had a lot of output, so yeah, around 1-2 o'clock should be unity.

One cheap trick: switch the volume pot to 100kB instead. Or use 250k.

One other possible solution: increase the 220k (R7 and R18). Not too much...maybe 300k.

Mine seems to work 95%. Like I said, I'm still playing around with it to get a feel for the controls. One thing I noticed is that the "down" sweep seems to be behaving a little differently now that it is boxed up than when I tested it on my proto rig. There are only two things I can think of that might have caused this: I set the rotary switch incorrectly, or the LED indicator that's tied to the envelope might be screwing things up. I'm not sure yet. Or, maybe I just don't know exactly how it is supposed to work (probably not).

Other than that it is behaving.

There is no single sided version of the Dirtbag, unfortunately. It's possible to do one, but it would probably require at least a 1790NS type enclosure for the layout. I never laid one out.

As I mentioned in the announcement thread yesterday, I will be getting some more of the fabbed Dirtbag boards in soon.

It's the 'Moog' filter. There's a description in the meatsphere thread over at DIYSB.

I took a lot of inspiration from Haberdasher's recent Collosalus build (IOW, I stole his idea mercilessly) when putting this together. The artwork was liberated from the internet and then I added the text, etc. I dig the look, although I think I will go with all white knobs eventually.

This thing has some serious fat sounds. It will take some learnin to figure out all the settings. And, it's so damn big! But, it was a fun and challenging build.

The Meatsphere is a project on www.musicpcb.com. Great board and layout from Taylor!

The Kingslayer will be in the next batch. If I get the prototype in time I might also do the Sparkplug. I'd like to get a couple more overdrives so these would be great.

The Retrograde is actually done, too. So, that one is a go. It will probably go in the batch after. The Deadringer I may not end up doing.

Karate Shop restock?

Yes, I will be getting more of those with the next order.

So, in light of recent events (some financial hardships which I explained a month or so ago) I have slowed down project development and the release schedule for the coming months. Which is not to say that I will not be releasing any new projects or cancelling anything. More that I will not be releasing 10 different PCBs at once like this last round.

So, what I am planning on doing is trying to put out one or two new projects about every 6-8 weeks, plus restocking PCBs that get sold out. I think this is a pace I can maintain and afford...and I think that's pretty reasonable, too.

-- I WILL be re-stocking the Dirtbag. It seems there is still enough interest and demand to build it, so I'll get some more made on the next order.

-- I am still working on the new Aquaboy and Aquaboy Deluxe versions.

-- The Stage Fright, Nautilus, Harbinger, Zero Point, etc (all the stuff I've mentioned before) is still going to happen when I can get them finished and fit into the schedule.

Basically, all the big fun stuff I still really wanna get done so even if I am not giving updates regularly on them, don't take that as they are not going to happen. I'm still stoked to get a lot of these things to completion.


Anyway, if there are any questions about this, fire away and I will answer.

That is outstanding!

Finally got around to boxing this one up. I'm quite happy with it now. It's got two switches for clipping choices. One is for hard clipping and one for soft. The hard clipping selects between two red LEDs, none, and two BAT85. It sounds like a vintage / Marshall kind of choice. The soft clipping is BAT46 doubled up. This is similar to the vintage hard mode, but a little brighter. All around enough choices to make me happy. The LEDs are my favorite I think.

The actual circuit is basically the Klon, but the power section has been simplified so it runs on +/- 9v. The IC is an TLC274BCN. The LM347 also sounds good.

So, this one is done. I'll be looking to get some made pretty soon. Demo to follow.

The regulator should have the label facing up in the Road Rage. Make sure the large metal tab on the back does not touch the pads for the SAG trimmer underneath. I may have forgot to mention that part in the build doc.

What I did changed was for R11 and R12 39K instead of 68K. Somhow I liked it better with those values.

What effect did/would this have?

cheers,

It reduces the output of the compressor portion of the compander. IIRC, 39k is the value used on the Memory Boy which uses 4x BL3208a.

I'd say it is a fluke. Changing R3 doesn't alter the voltage divider created by R24/D2. The 10k is fine. Glad you got it working

The larger value pot means the resistance to ground increases as the pot is turned towards max. The larger resistance means more of the signal passes to the output rather than being shunted to ground.

I've noticed that the Tiger Lilly is now not a thing and does nothing.

It would fall under the "More baby boards" under "in development". Technically, it is still a thing that does nothing ATM.
