One of my pedalton started to sound weird. Short story when I use the 1.5 watts amps it gives me a pretty loud and bizarre noise similar to a big Hum noise or a guitar Jack unplugged at high volume. When I turn the drive knob the noise change. I swapped the tubes with my other Pedaltone and all the tubes are find. What could it be. This one is pratically new:confused-smiley-010

Can somebody help me please?
