Hey guys how's everything goin ??
I'm just wondering if anyone could help me out... I've wired up a few CBG's successfully but lately i've been having a few problems with humming / feedback..
I'm just using a piezo buzzer with a volume control and of course a 1/4" input jack. For some reason when you plug the guitar in, there is a slight humming sound. When you touch the volume knob with your hand the humming sound is really maximized. And what seems even weirder is that when I touch the metal on the guitar lead / input, there is a dead silence with perfect response from the Piezo.
I'm just wondering if anyone has experienced this or if it's a common issue!?? I've got a couple of pictures on my page that show you exactly how I've been wiring them up. Thanks in advance!!
