Just installed a copper light weight trim kit on my 2335. Although it's advertised as being light, the total weight of the horn has increased a bit. The appearance is stunning. The playability is very good, but have not played it enough to get a good feel for the subtle differences. It seems the feedback and slotting may be a bit better now. The machining is world class first rate. The tolerances are amazingly tight. I guess my Yammie has been totally "pimped out" with the addition of this Harrelson kit plus the heavy weight Xeno upgrade kit. Has anyone else purchased these kits from Harrelson? If so, what is your experience?
