Everyone talks about putting a 15 with another 15, why. The rig I use to play was a SWR750 head, Aguilar 210 and a EV15. I loved that rig a lot, but getting older now and I got tired of hauling that all around, I bought a MarkBass Jeff Berlin 151p and its nice, but I like to add another cab with it sometimes to get the full 500 watts are close to it. So I need another cab and everyone tells me i need another 15. Personally I wish I had kept the SWR, the MarkBass is okay. I tried a PV210 cab but it sucked. I wish I could trade for the rig I play at church, Its a 15year old SWR350 and a SWR410 cab same year. They were stupid to quit making SWR. So what cab and I can't afford right now a MarkBass cab would you use.
