Looking into doing the external preset mod on my Nova delay. There's a bit of info floating around the internet about it, but I just thought I'd see if anyone around here has opened their Nova up to increase the functionality.

I think I'm going to use a two switch external box connected to the preset and manual buttons, like this guy does: http://groove-electronics.blogspot.com/2010/03/tc-electronic-nova-delay-external.html

I clicked on a few of the pots at saw around 6 CDN. Maybe I just clicked on a couple more expensive pots..

Nice. That's a great layout too.

Yeah it was a really clean layout. Felt organized the whole time I was putting it together.

Great job man! I love the synth knobs and points for top mounted jacks.

Thanks! I love the knobs. Top mounting can be kind of a pain when it comes to fitting everything in there, but once it's done I'm glad to save pedalboard space!

Excellent job!  Strip board is always a pita for me. You nailed it.

This is why I love madbean. Everyone is encouraging. I posted a pic of this build over on TGP in the "DIY Builds Not From Kits" thread and it was deleted within 5 minutes with no stated reason. Maybe it wasn't "DIY" enough?

I've used the CTS Series 270 pots sold by, at least Digikey, that have 1/8" shafts, great range of linear/audio values, switched or not switch and not cheap.

Those look like they might work, but I don't want to pay $5+ per pot!

I finished up my first stripboard project. 808 with clipping switch. I used the layout over on tagboard.

Fired right up the first go around

Every time I complete a new build, I feel grateful for this forum and all of the very kind people who've helped me so far. Thanks!

I have a box full of hundreds of old HAMM radio knobs and stuff from my grandpa. I'd like to use them on pedal builds but some of them won't fit on standard Alpha 16mm pot shafts.

Google isn't helping much. Are there places where I can find standard value pots with a smaller shaft these knobs might fit on?

Thanks!

Even better, break out the breadboard and see what you can make happen.

That's a good idea. I should breadboard this stuff first.

This article called Cook Your Own Distortion has been really helpful to me in getting a grasp of opamp based OD circuits. You can breadboard based on what you learn here for a long time. Even a good old Tubescreamer has plenty of mods that involve caps, resistors and diodes.

I can't wait to see what you come up with!

That looks like a fantastic article! I'll dig into it in the morning. With this project I'm really hoping to learn a lot more about what components do and how different circuits work.

Anyone else want to throw an idea into the ring?

As I spoke of in a previous thread, I've decided to build a pedal using only parts that my (recently deceased) grandpa gave me. He left me a ton of resistors of all values, lots of different diodes, some different ICs, and various film caps.

I don't know the values of some of the caps, so I'm wondering if there's an overdrive circuit you'd recommend that handles a lot of experimentation with cap values and subbing out ICs. I'm looking for something I can build on stripboard, and socket caps and ICs until I find something that works for me.

Any suggestions?

Thanks!

Yeah, I think I'm going to try to find something that I can build with only parts I found in his shop (plus jacks, 3pdt, enclosure).

My wife's grandpa recently passed away. He did tech work on radios during World War II, he designed the computers that run the public waterworks system in Des Moines, IA, was a huge amateur radio enthusiast, built his own color television back when no one had one, and was on the cutting edge of technology his entire life. He could fix or build pretty much anything.

Before I married into the family he had no one other than his old HAM radio buddies to talk to about his passion.

When he passed away his daughters asked me if I would like to look around in his workroom and take whatever I'd like. Grandpa Bob built his house himself in the 30's and lived there his entire life. 3 out of 4 rooms in his basement were his "workroom."

So today I went over and poked around for 3 or 4 hours.

I'm hoping that I can take some of what he had collected over the years and put it to good use.

This is what I found:

I really like the fuzz tone Gary Clark Jr. has in this live video. I'd like to find out what kind of circuit it is!

Thoughts?

*UPDATE*

I just wanted to give a quick update.

I put some more work into this build over the last week or two. I ended up melting my 3pdt while trying to redo some wiring. That got me thinking... maybe I had just been too hard on my 3pdt switch by taking forever to solder stuff and by applying heat multiple times (each time I rewired). I thought maybe that had been the cause of the weak output volume.

Anyways, I swapped out the 3pdt and used a different offboard wiring method than the Madbean diagram. I also wired my LED offboard instead of using the spaces on the PCB. This both solved the "light is always on" problem and solved the volume drop problem.

I just wanted to let y'all know that I finally triumphed over this lil guy and to say thanks to everyone who offered some help. Also thanks to haberdasher for the great PCB.

Oh, is your led still lit all the time? I just went back and reread the op. Your led is grounding out somewhere, that would cause a volume drop in my experience. Check the wire that goes to your led. Does it do it in and out of the enclosure?

Yes, the led is still on no matter what. 

Before I boxed the effect it was not on all the time. Then I boxed it up and it was still functioning properly. Then I noticed that the output of the effect was low so I took the circuit out of the box and redid all of the wiring. Since then it's been on all the time. I can't figure out why. I've gone over the LED wiring a dozen times.
