I know you prefer the
Marshall, but I personally couldn't disagree more.
Not to say it sounds bad. But since it came after the 5150, to my ears, it certainly doesn't sound better. I don't hear it as being more dynamic whatsoever. If you look at the waveforms, I'd bet a million bucks the 5150 has higher peaks because of how that low-end responds. The Marshall doesn't sound nearly as full. The low-end sounds thuddy and spongy by comparison. The attack also sounds kinda soft. Somehow I feel it sounds both looser and thinner.
I'm overly exaggerating, TBH. But it's kinda hard not to when you're comparing both so directly.
But I don't mean to come off as a douchebag hater. I just liked one tone more than the other, but both were great and I wished I had either amp, LOL.
