Are there any one that have used older fender 50-100 watts tube heads on stage ? Like the 50 watt Bassman or The BandMAster. Is a 100 watt tube amp to little for stage ? The amp in question is a dual BandMaster by Fender (1964). I know that they was popular by bass players back then. And they have 90 watts (4 x 6l6) of power. They are called dual because they have twice the power of an ordinary BandMaster.
