Someone I know recommended the mark bass. I haven't had a chance to check it out yet. Any recordings you can share?I use a Markbass mini stack rig for pure utility purposes. But since it's sort of neutral sounding I put a VT Bass Deluxe in front of it and it does a pretty great job of copping that old Ampeg tone (with a P bass, of course). You can dial in a B15 tone as well as an SVT. That seems to get me solidly in the ballpark.
