Here is a lovely Epiphone Zephyr Blues Deluxe. The guitar is the Epi version of a Gibson ES5. She sounds and plays great. But the ES5 controls were a bit awkward to use in a gig situation. So we modified it… The guitar now has a three way pickup selector switch that operates exactly as you would expect it to. The three rotary controls are now master volume, master tone (with bridge pickup phase switch) middle pickup volume (with switch to turn the pickup on or off). The T-Bone Walker sound is now available with ease :o)
