I'm currently playing an Acoustic B200 head through the matching 4x10 cabinet. My friend wants me to indefinitely borrow his original Sunn 2x15 cabinet - he can't play anymore due to tinnitus. I'm wary of using up all 4 ohms my amp can handle on the bulky beast and not having the high end definition I enjoy with the 4 10's. I have an Eden head that needs to be refurbed and I think the Sunn plus a 4x10 will work with that. Any opinions? Btw, I'm playing a Fender Blacktop P-bass (passive).
