Mark A. Roth Piano Services offers skilled spot repair. Not all technicians have these skills. What this means to you the customer is that little problems can usually be taken care of "on the spot." Of course, I cannot carry parts for every contingency, and sometimes repairs can be major, but it is nice to know that your tuner is also capable of fixing little problems that commonly occur. (I have even heard of one guy who has a box that he fills with parts and keys needing repair, and when he gets enough he takes them to another technician to be fixed, then retrieves them at a later date and proceeds to return them to customers.) When you hire Mark A. Roth Piano Services, you can be confident that a couple of sticking notes can usually be fixed right away.
