I play bass in a new stoner/doom band. I am in the process of acquiring an Ampeg SVT-CL and 810e. Obviously I'm going to want to crank the thing pretty loud. However, I'm concerned that if I crank it, I'll overpower the guitarist, who will most likely be playing an Ampeg V4 (late 70's) with two 4x12 cabs. Ideally, I think we want the guitar to be slightly more dominant in the mix, especially since there is only one guitar. Is the 100W of tube power from the V4 going to be enough to dominate the sound over the 300W SVT? If not, do you guys have any recommendations to augment the guitar rig? Thanks.
