After 40 years it stands to reason some will sound better than others. But playing ' mail order roulette ' is still a gamble no matter what your buying. Most of my purchases are in person unless I know exactly what I am going to get. That being said Hendrix used to sit in Manny's music and play EVERY Wah, or Strat to find 'the one'. Even new gear still has variances piece to piece. These things are priced with consistant pace of the old Marshall amps and Cabs they were designed to push. If mine were stolen, I would not pay 1k to get one off Reverb. But I would pay it to get mine back. Even at the high water mark of 2k, I wouldn't think twice. If your not playing vintage Marshalls, Vintage Marshall Cabinets, you probably don't get it. And Yes, that Reverb POS sucks and you shouldn't buy it, UNLESS you pluged into it in person with your gear anyway, big win for Fed EX or UPS , again. But then again SRV said so, no he didn't, he played his ass off, he did not need pedals, so your misled. Take a deep breathe, and practice, it cures ALL. Green Pedal Bad. Practice Good.
