I was referred to Dennis from a local dealer and got confirmation regarding his work from a good friend. From the minute I walked into his shop, and was informed of the dangers of carrying my amp in the rain, I knew I was in the right place. His shop was organized, clean and his attention to detail was spot on. When I picked up my amp it was cleaned and working like new…my sound was back! I would highly recommend Dennis to all of my friends and will use him for all of my amp repairs. Thanks Dennis!
