What do they call that color? I had a regular studio in Fireburst, and it looked just like the 3 color burst that Fender has. The black carried over to the back of the guitar and neck.
Does it have a red back?
Are those chambered? I have two p90 guitars and the Gibson is the least noisey of the two. I use the middle position, with the volume controls matched to cancel the hum.
Any high gain amps just make it worse.
