I just picked up a older GK800RB that has the horizontal switch for dirt cheap on CL with rack ears and a nice roadcase. For over 3 years I have been playing a newer one, not sure of the year, with a vertical switch. I dont really need two of them and am debating which one to let go. There in similar shape, my newer one has some scratchier pots and the owner of the older one said he actually had all the pots in it replaced. I honestly cant tell a tone difference in them, I was just wondering if the older ones had more value or anything like that. Thanks.
