Obviously, there is some nostalgia, but JV-1080 is really a classic. The factory presets can be outdated, overused or bland, but a lot of presets are still excellent, intemporal.
JV-1080 sounds generally warm and full. The only really weak point is the reverb, IMHO. So cut the reverb, use a very good one, eventually use HP and LP filters, and the JV will be at his best.
You have also a mass of user's presets, with some treasures.
