After having my Peavey 6505 head serviced by Dennis and reading through all of his previous testimonials, every element of each one seems to hold true in the quality of service I received in a reasonable amount of time at a very reasonable cost. From diagnostics to every problem you have noticed by him to problems beyond. Dennis goes through every measure to perfect your equipment and will inform you of every bit of work that has been done to it. I would recommend anyone I know with professional equipment and problems in Jacksonville to Audio 3000
