oh yeah baby
Heavy! God it's heavy! And a bit rattly, to be honest. But sound-wise.... oh what a pleasure it is. i use it with 2x the 2x10 Ampeg cabinets and it is fantastic
Very happy about this amp . not too powerfull but still very dynamic , full and warm . i play a short scale SG bass on it and a fender jazz bass and even a Gibson E335 guitar it all rolls cosy and easy . As i use a vintage marshall JMP 120 on marshall cabinet . the addition of the ampeg 4VB is adding cosiderable depth that compensates for the clean biting mids of the marshall .
best 100 watt tube amp
best tube amp which is not that heavy and still has enough power to keep up with loud guitar amps!
creamy and tight! love it
Amazing sound but with build quality issues
It has the expected all-tube amazing Ampeg sound and provides all you need for up to medium-size gigs and probably even more. It is a great sounding amp either paired with the 212AV or two 210AV, mostly suitable for studio work.
But even though it is not the top model of Ampeg I would expect a better build quality. For example the tubes are not mounted properly and steadily as in the case of the SVT. Additionally they are mounted at the top instead of the bottom as in the SVT which is also the logical and safe way I believe. For these quality issues I am reluctant using it at a live performance and use it only at home.
Conclusion: For this price tag the build quality issues I mentioned shouldn't appear. Hopefully no issues will appear any time soon - even though the build quality unfortunately suggests otherwise. Highly recommended in terms of sound but with caution.
