Is there a huge difference in achievable tone between these 2? I was looking at a 90s version of the Mesa, not a powerhouse. With no way to hear them at the same time, I'm very unsure. I play mostly classic rock and dance top 40 covers. My head is a Mesa M Pulse 600. P bass and Jazz basses. Right now I use a Powerhouse 4x10, I'm looking to get into a bigger cab, not use both.
