He surely made some great instruments.
I guess it is nice to know he still offer customer service for those who owns one of his basses.
I regret selling my Jerry Jones Longhorn, it was such a great bass to play (even if I like the playabillity of my Ibanez Mikro even better, but the Longhorn comes in on a close second place regarding playability of all the bases I have ever laid my hands on) and had such an unique lovely tone.
And while I do love the tone I get out of my Mikro in conjunction with my Trace Elliot GP75SM 130W 15", which I would describe as a punchy mildly agresive tone, I equally loved the warm hollow body tubey tone I got out of my Longhorn in conjunction with my Ampeg B-15S (which I also have been stupid enough to sell), a tone I would not be able to even get close to with my current gear.
