If your rig has more than one amp in it and you are experiencing excessive hum or buzzing then you may have a ground loop. A ground loop is an unwanted current in a conductor connecting two points that are supposed to be at the same potential, often ground, but are actually at different potentials. Ground loops can be detrimental to the intended operation of the electrical system. Translated into guitar amp terms means that if each one of your amps in your rig has its own ground then you will have a ground loop and will get all that nasty hum. In a multi-amp set-up you only want to have one of your amps grounded. How do you only ground one of them? Simple, by using ground lift adaptors on all but one of them. This also applies to any external reverb unit like the vintage Fender units. Doing this will eliminate the hum and keep you safe from any chance of electrical shock. Ground lift adaptors are available at harware stores and even at supermarkets.

David Nicholas - The 20watt amp is sounding fantastic! Delivered the goods at the gig and I'm finding cool tones all over the place with it. Love the cab w Emenince Tonkerlites too- perfect for my sounds! Makes the 12 string sound like a grand piano!
Peter Lacis - I had an audition for something recently that was all about Led Zeppelin I -- my custom Pennalizer BLEW THE MINDS of the guys I was playing with. They couldn't believe the sounds coming out of that amp. That album was never in my mind when I came up with the idea....so that's yet another testament to the amazing work that you do.
Scott Goldberg - I am very satisfied with the set-up, and the fast turn around. With the "lower" action it feels easier to play. I will definitely spread the word.
