I have been a Peavey 5150/6505+ user for about five and a half years. For the last year though, I really wasn't happy with the amp and was researching for a new one. I finally decided on a Stiletto Ace 2X12 combo. Besides the fact that it sounds awesome and looks great, the things that came with the amp really caught me off guard. The fact that it came with a very nice cover, a bag for the footswitch, removable casters (GREAT idea), and all of the documentation in a plastic folder just astounded me. I'm sure most of you have known about this for a long time, but me being new to Mesa/Boogie, I was really surprised. I have heard that Mesa is a great company to deal with, and now I really understand why. Kudos to Mr. Smith and company for the great job. Not only are their amps light years ahead of the competition, their customer service is, too. If other companies even did half as much as Mesa Engineering, I bet the amp industry would be very different.
