Re: Fender H.O.T. practice amp hum (50hz) noise even the guitar is un plugged.

Hello people, I still not have luck finding where the background noise come from. As I said in the last post when I plug a lead cable in the "POWER AMP INPUT" the background noise disappear. I attached a picture of the schematic where you can see the mixing stage, tape input, reverb and vo...

Re: Zvex - Lo-Fi Loop Junky

I found time to play with the 2 x Loop Junkies today. Had some fun recording a rhythm guitar loop on one, then recording both that and a bassline onto the second. It's also fun to record different loops on each pedal, play them together and they slowly slip out of sync. For the money, hmmmm, even t...

Fair enough. Can't you upgrade to the latest version of Java anyway? That way you should be able to run the universal build.
