Once in awhile I will gig with one of my guitar player's Ampeg V4 + 810 cab. Then, later back to my Markbass LMIII head with two Markbass 115 cabs. My friend thinks his Ampeg rig sounds more even, or consistent as to how the notes are hearable. He said that with my rig sometimes notes don't project as evenly. Hm, I've been trying to understand why that could be. Of course, maybe it was my playing, or perhaps my eq doing it. I'm not sure. But, it dawned on me that maybe it has something to do with tube compression. I don't push the V4 hard, though, not at all. But, still, is is possible that that is the cause, if it's so? Under what conditions could the Ampeg be so? Maybe it's just my friend's ear, but I thought I'd ask. Thanks.
