I just acquired an '05 Corvette FNA Jazzman. Everything frets out above the 12th fret. My local tech was having trouble moving the truss rod and quit before causing any further problems. Before I open a can of worms by sending this to the custom shop or Germany, I'd like to get the opinion of someone that works with a lot of Warwicks. I'm looking for someone in South Jersey/ Philly area. Any recommendations would be appreciated. Thanks.
