Hi. About one year ago I have purchased a JP Pramberger (JP208) grand piano from a private seller. The piano sounds great but I was told that it could use some regulation, voicing (mostly because I prefer a slightly warmer sound) and fine tuning (I had it tuned 5 months ago). I am looking for a reputable piano technician in the LA area (I live in the San Fernando Valley) that could work on my piano to make it sound at its best. Aside from David Andersen (which is supposed to be a real guru) do you have any other recommendations. Thanks!

Go to the Piano Technicians Guild website and use the "Find an RPT" widget in the upper right corner. That takes you to a page where you can search either by zip code or by specialty. Zip code will return everyone and the specialties of each will be listed. Or you can just look for specialties like voicing, concert work, university or whatever may indicate someone with an expanded skill set beyond tuning.

Thanks for your suggestion, but I am looking for one or more specific names of piano techs from people that have had some direct experience. I mentioned David Anderson because from previous posts I learnt that he has a great reputation. However, he lives a bit too far from my home.

How about Carl Lieberman? http://carlpianotech.com

He's been tuning for Sir Elton John this week in the recording studio!

Nice find. Thanks! Isaac Sadigursky also has a lot of good reviews on the web. I will call them both tomorrow.
