Hi, I'm wondering if it's worse a penny to grab an ampeg v4b 90 slm reussie or should i wait a 70"s magnavox up for sale ? Is there any difference in the schemactics ? I could find the 70's one but impossible to find the 90's one. I'm currently playing on US ampeg-svt pro 3 with US ampeg 4*10HLF (which i use with analog synth that goes really in low freq in the cab got it quite well), i'm wondering if adding a second 410HFL with an ampeg-v4b would be the good compagnion for that rig ? Or should i go for cabs like accugroove or barefaced (which seems promising) and a 100 watt head of another brand ? I play loud rock with DIY fuzz pedals, that goes from doom/drone to black rock (think about shellac to give you an idea). Regards.
