A bright, 7″ multi-touch display makes building and tweaking signal chains as effortless as using a smartphone—drag, drop, and swipe your way to brilliant tones.

— Jeff S., Alpena, MILegator Ninja N6FX
Overall great customer service and very friendly demeanor from Matt and Kristen at Drop Dee. Guitar matched its description perfectly and included everything as listed. Great setup out of the box and I can already tell this will be my main guitar from here on out! Do NOT hesitate to shop with the fine folks as they’re incredibly helpful, and very very friendly! Thanks for the Custom Shop Strat!
— Joshua T., Bluefield, WVFender Custom Shop 57 Stratocaster Relic
I must say, I've had enough of mass sellers like SweetWater with their extra fees for everything that should be included as part of a guitar sale. Drop Dee Guitars exceeded my expectations by far with my order, ensuring that my instrument was a joy to play straight out of the box. I eagerly anticipate future business with this store. They are truly a shining star! Excellent communication throughout the pre-sale and after-sale as well. Thank you!
— Jose M., Port Matilda, PACharvel MJ San Dimas Style 1
Great People, Great Guitars, Great Setup. Can't ask for any more. Also look at their website their artist relations manager is awesome.
