Crybaby GCB95... Mod time

[Paddyob]

Ok. So my first screw up was repairable.

Solder bulb. Garbage. Solder braid. Amazing.

What a difference it was to remove solder with a braid in the second component.

Mmm hmm.

So long as it is has rosin/flux or is labeled as "no-clean" it is gonna be good. Don't try to save a few bucks by buying the cheap stuff-- it just doesn't work. I threw away 5 rolls of the stuff.

BTW, if you are ever salvaging old parts from used electronics, I recommend the safety glasses/blow torch/smack it on concrete method. Works like a charm and, again, pretty fun.

.022 too bassy. Replaced with original value .01 in tropical fish.

I would try the .015 but I may have over heated them on the first attempt.

No idea.

Get a decent pump as well, if you can. The bulbs are kinda trash, but the spring-loaded pumps are solid. I keep a small one and a roll of braid on my desk, and have a larger pump for when things get... real.

The braid is absolutely the right choice for single-sided boards (like the one in that there crybaby), but it's not gonna work quite so well on double-sided boards that have plated through-holes. Even with the big pump they can be dicks. I usually just cut off the component and don't try to save it. That makes it way easier.

Led bezel installed. Still waiting on the 3pdt.

[Paddyob]

Buffer out. True bypass in. Led in.



Sound test tomorrow. But the led is working. That's a good sign I hope.

Nice work.

I could see this wah modding continuing to a pot or rotary to set the sweep frequency range, a resonance control (is that possible?), maybe even an lfo or an envelope follower to supply the control voltage. Adding a Morley-style LED/curtain system to work as a secondary variable resistor so the treadle could be used as an expression pedal to control another effect at the same time - that would be interesting. The possibilities are endless!

[Paddyob]

Yup. That's the plan.

Trim pots I know very little about.

[Paddyob]

Sound test. Awesome.

Uploaded a sample to YouTube.

Excuse the shitty riff. It was following a late night of soldering. :P

Sounds ok. And I'm not done.

[Paddyob]

Oh shit. I just added a sweep switch. Easiest thing in the world of modding so far. Used a .01 and .022 tropical. Sounds awesome.

This is possibly the best detailed mod thread i have found. Pictures themselves explain it. He covers the mods in good detail and easy to understand language.

Another switch! Vocal mod! Stock 33k and suggested 47k. Apparently a Clyde McCoy has a 100k in this position, but it could lead to a distorted tone. Ill playboy safe and go with another popular value.

[Paddyob]

Oh I just got a cool idea.

I'm planning to add a 100k pot for the Q control... But I'm planning to put it behind a switch so it can be shut off. Select either stock resistor value or mix the Q.

That would work, right?
