Is the 450 watt Mark bass 210 combo really $1000 better than the Ampeg BA 210 v2. My guitar player has tried to convince me but I just see it as extra money going bye bye...am I wrong?
That's more or less subjective to you. I feel that Markbass combo is really good and a much better choice than the Ampeg. If you are looking at upgrading your gear, a separate head and decent 210 cabinet will probably be much better than both of those. You have options with future gear that way.
I used Markbass for a little while...dug the heads, but grew to dislike the cabs. Too upper midrangey for my tastes.
