So, I had 2hrs to kill while my wife got a massage today and decided to check out a consignment music store. A Sunn 300T and 215 peaked my interest so I gave it a run with a MIJ P Bass. Damn it sounded good. Just to be sure, i plugged in some garbage Fender copies and cheaper heads. Still sounded great. Just amazing tone and perfect for my style of Blues. I'm a younger player so I missed the whole huge amps thing. A 212 and 410 are as big as I've ever owned. Not anymore. This was amazing, cant wait to use it with the Ampeg V4B. My 212 may not see much use anymore.
