Bob Ackerman, the "Repair Doctor", is the experienced technician who has run our full-service electronic musical instrument repair shop since 1986 at Cascio Interstate Music. He also offers warranty service for over twenty manufacturers. Bob continues his electronic education annually at service seminars run by the Musical Instruments Technicians Association (MITA), and he is well-qualified to service your piece of equipment.
* Tube Amplifier Repair
Bob Ackerman's specialty is tube amp repair. It's no secret that, just like a high performance car, tube amps require the occasional trip to the "garage" for maintenance and tweaking. With his many decades of experience repairing tube amps, Bob Ackerman is the "go-to guy" in Milwaukee that knows tube amps like the back of his hand. Bob has worked on the oldest vintage Marshalls to the current amp models.
When you trust your tube amp to Bob, you can be sure that your amplifier will receive the same kind of attention that touring headliners come to expect from their personal amp techs. Bob will personally discuss your amp's needs with you before proceeding, and then repair your amp as if it was his own (and trust us, he's finicky!) When you get your amp back from Bob, it will have the roar, grind and punch that made you fall in love with it in the first place!

Packing & Shipping Information
When sending your instrument for repair, make sure to use a sturdy box. You can even double-box the instrument for added protection. Also, be sure to use plenty of packing material around the instrument. If using packing peanuts, first enclose the instrument in a large garbage bag to keep the styrofoam from getting into the instrument. When sending an instrument, it is also recommended to have the package insured. If you are shipping a tube amp, remove the tubes and send them separately to prevent breakage. If you are shipping a combo amp head, remove the head from the cabinet and send the head only to save on shipping weight and to prevent the possibility of damage to the speaker. Before sending in a product for repair, you will need to print and fill out a repair ticket (click here). Please ship your repair to Bob Ackerman at 13819 W. National Ave. New Berlin, WI 53151.
