Well, I’ve been putting off this entry because I was hoping I’d have better news, but it’s been a week so here’s the update. The Gristlelizer is complete. It turns on. The LED glows, and when I adjust the Speed potentiometer, it speeds up and slows down. Neat. In “bypass” mode, I can clearly hear the signal source.
In Effects mode, nothing. Nada. Zilch. Zip. Zero. The big empty. Nothingness, not being.
I have never been so frustrated in my life.
All right, neither of those statemtents are quite true. But I really am frustrated. Here’s a rundown of the Gristlelizer’s current condition:
— Sound gets through fine in bypass mode
— When source is cranked and amp is cranked, you can JUST BARELY hear the source in effects mode. You can hear noise from the Gristleizer, though.
— The speed control is definitely doing something, as it makes the LED blink faster and makes the hum from the unit modulate accordingly.
— The shape switch similarly seems to be working.
— bias seems to be doing little if anything.
— level similarly seems to be doing nothing — EXCEPT that it will cut out the source sound if turned all the way in either direction.
I’d hoped for so much more!
I contacted Justin, who so impressively documented his Gristlelizer-building experience here:
That’s pretty much what mine looks like — uh, except mine doesn’t work. I need to give major thanks to Justin who has been very generous in helping me try to troubleshoot what’s going wrong. All the obvious things SEEM to be OK so far: the capacitors and diodes and transistors are placed correctly, the solder joints are good. Thus far I’ve also rewired all the pots and switches, and broken out the multimeter to begin testing all the components. It just doesn’t WORK.
I am wondering if I may have fried the integrated circuits. It’s only a couple of bucks to get sockets (which I should have used in the first place) and some new IC’s, so that’ll probably be next step in troubleshooting. Wish me luck, and stay tuned. If anyone else ran into any obstacles in the course of assembling their devices, please chime in — I’ll be quite grateful for any feedback or suggestions you can offer.
