I accompanied a friend of mine to go check an old VHT 4x12 cab. The dude selling it was offering a pretty good price for it (around 150euros) so it sounded like a deal. So we go to the dude's place. We fool around a little and talk music, bands etc. and then we test the cab. We hooked it up to a Mesa 2x90, an ENGL preamp and an R&R preamp. While noodling we both noticed that the D3 (wherever fingered/played) was overpoweringly loud. Like it resonated the whole cab and buried other notes in relative loudness. We tried moving the cab around but it did not help. The cab was on casters which the owner did not want to remove (to test if it affected the tone in any way). Is a problem like that fixable? We said to the seller that we'd communicate again soon, but if such a problem is not fixable there is really no point.
