Ampeg B40 4-10 (vintage 70s)
Any thoughts or experiences with this thing? It's a rather large 4-10 from the mid 70s. I'm thinking of getting it (found one locally) and maybe putting some modern drivers in it. I have read some old threads on that subject here and there seems to be one Eminence that most like in that cab. It solves my cab width problem to go with a V4. The V4 is 26 1/4" wide and the B40 cab is 27". Of course, if it sounds fine as is I will just leave it stock. I would have to completely make a grill and frame for it as the one from this cab is missing, but that shouldn't be too hard. I'm sure fliptops or somebody has a cloth that will match the V4 perfect (or real dang close).
Anyway, anyone have good, bad, or indifferent experiences with that box? Any thoughts at all that jump to mind when you think of it?
