well, Mullard tube came today, safe to say i wont be using the EH again. As soon as a i put it in and switched it on, the difference was massive, the eh just sound brittle next to it. The mullard wasnt nos, but from the looks/sound of it it hasnt been used much. its the one with the shield logo with british made printed on it, bit worn off by can make it out. My particular valve is lower gain than the eh, which benefits me if anything, sounds fantastic, so much more character than the eh, more transparent and warmer (better bottom end and less highs) . id still like to experiment with more valves, but i cant see anything beatin the mullard.
