Customer Reviews:


"Just wanted to say thanks Bills Music for being an upstanding business in our community! Ron Cook is the best and my instruments have never sounded better!" ~ Scotty V.

"I brought my Epiphone Masterbilt Acoustic Electric Guitar to your company for some electronic pre-amp work and have a SUPERTUNE. I must say RON COOK is the best guitar specialist repair tech in Maryland. After one year with Epiphone guitar company that could not find the probelm with the eSonic2 per-amp, Ron found and fixed the problem on my first visit to Bills Music House. Ron Cook's SUPERTUNE is the best guitar setup in the UNITED STATES. Ron Cook is second to none in guitar setup. I am so pleased with the work your company has provided. Thank you Ron Cook!"
~ Marty C.

Just wanted to say that Ron did an awesome job on replacing my pickups and super tuning my Stratocaster, the guy's an artist! As a matter of fact, I'm bringing my other Strat in to have the same thing done. Thanx Ron, you are the MAN!

Bill's Music Service Department: You guys are the best. I guess that's why I drive from harford county to get there. Thank you for giving me 33 years of quality sales and service.
