I just upgraded the pickups on my 2011 Gretsch ProJet to TV Jones Classics. It is a fairly substantial job and requires particular parts. Prior to my order, I spoke to Earl, who gave me all the information I needed. After I ordered, Lynne emailed me to let me know that I had mistakenly ordered the wrong part, despite Earl's great advice. She offered to fix the order before sending it. I also had another question that Lynne answered with remarkable quickness. I have had a great experience with TV Jones and, having just had the install done, I can say that my guitar sounds amazing. I am extremely satisfied.
