Awesome Customer Service

Bought a Mesa Boogie 4 x 12. Soon as I purchased online they called to verify my order and to ask questions about purchase, shipment, etc. They made sure I was truly satisfied with my order. Even checked in again after I received it. I wouldn't hesitate to buy from them in the future. Thanks Sweetwater

Everyone uses them for a reason

This cab is the standard by which all other cabs should be measured. For one it has proprietary voiced V30s from celestion. And aside from a few select marshalls this is the only way for you to get Vintage 30's that are still made in england. The chinese speakers are good but these just sound fantastic. I play mostly metal and its no secret that many many bands use this cab. And for good reason. They sound amazing. Even if your not into the sound of mesa amplifiers the sound and quality of this cab cant be denied. How many 6505 cabs have you seen on stages lately? Not many. But most of the time you will see that bands 6505 sitting on one of these. Great mids, great definition. I had a sound that was in my head for a very very long time and through countless amps and pedals I finally gave this cab a shot and nailed it. This is one of the few products on the market today that is being used by darn near everyone and isnt sitting on one single ounce of hype. Its the real deal.

Mesa Amps aside, there is not much to say about this. Even people who don't like Mesa's amps know that there is just something about this cab that others don't have. It's true, to be frank, it's just got more balls and it is very articulate. They're the best cab for any musical background. Other cab's simply can't produce the kind of magic this thing does, it's untouchable.
