I've read here and there of those who have had their DRRI hand wired to DR BF specs. Would anyone here who has had this done say if it's worth it in terms of sound quality? Is it comparable to a real '65 DR? What is the cost, and who is doing this kind of work? Finally, would someone just be better off buying a new Vintage Sound amp? Sorry if this is redundant as I'm seeing this has been discussed before and am reading up. Still, new input welcomed.
