You are absolutely right, that is why I am returning this one and I will not be getting another. You are right about tubes too. I may not even end up getting one that has any. I will try to find the best fit for my sound needs and budget.
Although the casing states revision "C00" I'd love to know what revision the board inside says. Anything older than a Rev G and The original person who returned it may pulled one over on where you purchased it.
I bought my 7PRO as a return (for $480.00) from MF nearly 3 1/2 years ago and it's been problem free.

I mainly use my Fender Super Bassman or Ampeg V4B, but I love the Aggy and use it regularly
