Sam Ash Music Stores

Mask required. Used horns are sold without used mouthpieces. One must purchase a separate, new mouthpiece

It easily depends if you are specifying used or new, what kind of heads, drum material, pieces, etc.... they carry just about ever electronic instrument you can think of

Call the store or best bet is try there web site

Yes they have many version of Epiphone Les Paul's as well as many other new and used guitars. I have purchased a few guitars there and the service is great.
