One of the reasons I figured this amp was worth the financial pain is for the inherent reliability of a handwired, solid wood cab, point to point amp. The amps I've had the least trouble with over the years have been the vintage ones made in the same way as the Vibroverb. I always carry spare fuses and tubes, every pro has to, so with regular maintenance and the usual care this amp should still sound fantastic every time it's turned on, long after I'm dead. I expect this to be the only amp I need for the rest of my life. That's the original manufacturing philosophy behind it, and the other classic Fender amps. I'm glad Fender have realized why their old amps are so prized and now make a small collection of hand-wired beauties. It's worth the extra expense. Like many players I just wish they'd add some more of the original designs to the range. If they made a handwired blackface Bassman head of this quality probably half the guitarists in the world would want one! There's been no need for service or repairs yet, but I've had only good service from my local fender dealers so I don't anticipate any problems.
