I couldn't help myself... I decided to swap the speakers in the VM for two of the blackbacks in my quad box. My quad box now has two G12Hs and two G12Cs - a classic mix. I was very pleased with the VM's tone after the switch over too... the old speakers sound really sweet. I was expecting them to sound harsh but they sound amazing. I went with 16 gauge copper strand speaker wire for both change overs and will keep the original Marshall speaker wires with spades if I ever need to put the original parts back. Well worth the effort.
