Apparently the TCL2272 should fry at 18v, but I've been able to do it.

It means it can handle a 36v differential. So, if you were running a bi-polar supply it could handle up to 18v either way.

The NE5532 is a good choice, so is the LF353N. And, don't discount the good ol' 4558, or the 4580, either!

Mouser has 5mm WIMA box caps. Poly film and some polypropelyne.

Also, for 1uF film, I suggest the Panasonic ECQ-V if you are ordering from Mouser. A little cheaper and sound just as good.

Took delivery on the remaining boards this morning. Firing up the printer for postage right now!

Higher resistance means higher noise, hence the use of metal film. I use carbon film for most of the smaller values because that's what I have and the noise impact is lower, or so I've read. It just depends on what I'm building...I usually decide on the fly.

These look as good as any commercial pedal out there. Nicely done!

Yeah, that's really cool. I think a single 2" support bar under the stomp side will work for reinforcement.

In general, I use metal for 100k and up. Below that I tend to use carbon film.

Looks like they have updated the desing for the DSO Nano since I bought mine:

Do you know what series they are? There will be a datasheet that explains exactly what the numbering means.

I'm think 1n and k tolerance, which is either 5 or 10%.

Let me see how it turns out first before I make a decision. I'd really like to build it, so that's a good sign that it will be done sooner rather than later. If I offer it, it would be like the Uproar---in small batches from time to time.

I still need to get the Weener Wah, reverb and vibe done, too, so there's a lot on my plate. Also, the Les Lius variant. I think I have some other shit, too...I dunno, I have like 15 unfinished projects.

Actually, I just got curious and counted the number of projects in my Eagle directory (never did this). I have 109 finished/unfinished! I need to get out more...seriously.

I don't know too much about it. Actually, nothing!

However, I did come up with a rough design for a bass-specific overdrive. I was messing around with the old Contro Fuzz design the other day, and thought of a way to mod it more for bass. It sounds pretty terrible on guitar, but with the right mojo it can be turned into a blended distortion that's layered on top of the clean bass signal.

Here's the built prototype so you can get an idea of the size. Also, I'm changing the name to "Karate Shop"....best to avoid any trademark infringements with the old name.

Man, that's good to know. Thanks for posting this! Sticky.

In other news, the PCB design is finished. I'll get this built up with some of the other stuff I'm working on very soon.

It'll go in a 1590BB long-wise and have board mounted pots. There will be plenty of room to work inside the enclosure, so no worries there.
