I have bought several NIBs, Sterns, MMR and one JJP NIB, DI. I have never experienced issues with a new pin as I have with DI (including damaged decals, trap door, split cab, failed power supply, messed up harness which took close to a month to trouble shoot with JJP amongst other minor issues). Has everything been perfect with the Sterns, by no means, but nothing to the scale of DI.
Having said this, I tip my hat to Frank at JJP who has been great in helping me with any issues I came across. Needless to say, very frustrating when after exchange, taxes etc my DILE cost me close to 13K Canadian and then having to deal with issues which in my opinion were not acceptable. Then the nail in the coffin was having to pay out of my pocket to ship back a crapped out power supply for a pin that was approximately 8 months old.
As much as I'd like a POTC, I vowed never to buy JJP NIB again and won't. Eventually they'll show up on the used marked.
