"Okay, I'll brag a little bit, because I'm proud to be of service."

Keyboards repaired

Greg has humility, but is still proud to service the Professional Audio Industry, so a little bragging is in order.

As owner of The Music Works in Philadelphia, Greg Granieri worked on many artists gear. Many times just before a show.

At 4pm on a Friday, Greg got a call from the management of Duran Duran. "Our Synthesizer Just Failed During the Sound Check." Duran Duran was playing at the Spectrum that night and their Roland Jupiter 8 failed during sound check...

The synth didn't survive the trip from Italy a few days earlier. Greg fixed it just in time, and the show went on!

How Much Will My Repair Cost?

This is one of the most frequently asked questions. It is also one of the most important questions. But...it is one of the hardest questions to answer without troubleshooting your damaged item.


Why I must Evaluate Before I Quote

The cost to repair an item can have a significant range. The amount of damage is the largest factor affecting the cost. Other variables considered in pricing include the cost of the replacement components, the testing required to verify that the item has been repaired correctly, and also whether there have been previous repairs or repair attempts. Only a thorough evaluation can produce an accurate repair quote.

There is a $50.00 fee which is absorbed into the total cost. This covers my first half-hour of troubleshooting.
