I have the MM30e/as model which has the piezo pickup under the bridge. The tone of this mandolin is excellent, probably because of the body material being mahogany which gives it a warmer tone than maple. All of the frets were fine, no buzzing, and the gold hardware and vintage logo on the headstock are nice appointments. I put on new stings and was very pleased with the tone, which should only get better. A lot of value for not much money!

Sure one can by up to a more quality instrument at 3 times the cost, but the MM 30S stands up to them all. Even the more expensive ones. I replaced the strings with D'Addario J74's and we are on a roll. Affordable entry level or used for most gigs. Like anything else one can always up grade, but unless you are playing professional and simply playing gigs and having fun, this is a sweet instrument at a great price.
