Anyone else have a similar issue? I have a MOTR Yamaha 5-string and have used the cabinet with a Hartke 3500 and more recently a GK MB500. I'm looking for a pretty fat sound so the bass was/is pushed on the amps. I'm thinking of going with the GK Neo 2x10. Has anyone paired this cabinet with an MB500 and a 5-string and doesn't feel the speakers farting out?
