I have a '74 ES-355TD that has the original stereo Varitone setup and T-top humbuckers. It has had a stoptail conversion and looks like it possibly had a very nicely done headstock repair. It plays well and looks cool, but after getting an ES-335 Dot RI with 57 Classics, I realized it paled in comparison tonally. The wound strings don't come through very well when playing live, and the clean tone is somewhat lifeless. It's just dark and lacking sparkle. I'm at a crossroads.....do I sell it, or do I try a new harness and make it mono w/o the Varitone? Are the pickups an issue, too? How about the guitar itself? I'm not worried about modding, since it has already had work done, but yanking and replacing the harness is not something I really wanna pay for twice if it ends up not helping. I've heard people say the difference post-Varitone was huge to them, so that has really got me thinking maybe that is my problem, but I'm just unsure. I could sell the guitar and be well on my way to getting a replacement, but this guitar has a lot of character and patina, and I like it. What would you do?
