Congrats Rob and welcome to the Distillate club. I have an '86 coco bolo, I love it. Your '83 has a shorter upper horn, the upper horn was lengthened in '85 to help the balance issue. As you discovered, a wide strap will help fix that on the early ones. A little heavy yes, but what a great feel and tone range! Feel free to ask the gang here for help setting up the trim pots/electronics, we have a lots of veterans here who are happy to help. Enjoy!
