"Hi Rick! You did an excellent job rebuilding my U67. Its kicking my M149. I'm very pleased.
Thank you, and I hope to have more business with you." —Best Regards, Rafik Tsaturyan - Real Sound Studios, Glendale California - 05/04

"Rick, first of all, I want to thank you for your advice last evening with regards to the problems we were having with our newly-acquired C12VR you repaired for us.
I took your advice and started over, making sure all AC connections and cables were good, and the power-supply plugged directly into a clean and tight wall-outlet.
I am happy to say that everything from that point was great, and the microphone worked for the remainder of the evening with superb results!
I can only thank you for all of your efforts and patience in helping me through this stressful saga. Since I purchased this microphone in January,
it seemed that nothing was going right. I'm very happy that I found out about your company and am glad that things worked out.
I wouldn't be surprised if our paths cross again sometime down the road; in the meantime, I will recommend your services to others.
Thank you again for your help." —Jim Wear Jr, What's Hennepin Recording Studio, Cedar MN - 04/07
