Pro-10 Overdrive build

[danwojaz]

Here is the build of my Pro-10. It is a very tight fit. I found that you can not use dust caps on the pots underneath the input and output jacks. Also, neutrik jacks did not work. The only style of jacks that fit were the ones I have in the build.

It looks like you have an original one too--notice any difference or is your spot on?

I'm about to order stuff for a Pro-10 build and am going for the same clone look. Do you happen to know if the pointer knobs you used are 24mm or 29mm wide?

It sounds very similar. With part tolerances and knob placement, you can get them to sound spot on. I am noticing a little noise when I play the blue side that doesn't exist on the original. I also have the Pro-10 blue pedal and didn't experience the noise on that one.

I built two PRO-10s dual overdrives and they both do the same thing. So, it is either a bad batch of components or something else. I will have to break out the oscilloscope and try to track the noise down.

Thanks for the heads up. Tight fits are always the tricky ones. Starting mine soon.

@Dan0h I built a second one last night and Tayda has these rubber Pot dust covers and I was able to use those for the two pots under the 1/4 inch jacks.

Just an update. I swapped the op amps from the Pro-10 Blue into the Dual one and the issue went away. I think I got a bad batch of opamps.

Sounds likely, I didn't have any noise on mine.

With the noise gone, I will say they sound the same.

Tayda? Or other source?

The TL0701s and TLO702s I got from Tayda were good and didn't have any noise. I forget the supplier I got the other ones from, but those ones were bad. I went through all of the ones from the other supplier and they all had that noise problem. @spi

The whole fact Tayda exists amazes me. Don’t even consider that you can get a box from the other side of the planet in less than a week for $15. So crazy. Kudos Tayda.

Good job! That orange peel on the Protein though.. yikes I’ll take my DIY build

Thanks for the info! Jacks can be tricky. I suspect that if the holes for the jacks were drilled further from the board it would have been less of an issue. I always drill the jack holes as close to the edge of the box as I can to leave room for the pots. That's usually around a 10mm centre from the edge of the enclosure. Still tricky for Neutriks and Switchcraft 11s but the Lumbergs usually fit easily.
