Just like the title suggests, who uses an acoustic 370 with an ampeg 810? I have a mesa powerhouse 1000 (410+115) and an ampeg heritage 410. Im selling the mesa and am looking to buy a heritage 810 for larger gigs (1000-1500 people outdoor and amphitheaters). I also have an svt classic I'd use with the 810. Theres nothing wrong with the mesa and its been handling my low end for 10 years but from my experience the heritage 410 leaves it in the dust tone wise. Mesa is louder though. My mesa is my big rig cab and the 410 is smaller bar without PA support rig.
