I built the thing, took me about 1 1/2 hours, and when I was finished, it buzzed like hell. After 10 minutes I found out that it was a cold solder joint, so I redid all the soldering... phew.
Now here's the fun part. I can hear myself play, sure, fine. But it doesn't boost. No boost whatsoever. Not even a change in tone. I tried plugging my guitar directly into m amp, and then compared it to the booster's signal. No difference.
Could this be because my battery is almost dead (I know this for a fact), or is it something I screwed up. I double-checked the circuit, but everything is in place as it should. Is the thing not working right because of the battery?
Or is it me being an ass?
