I have an Acoustic 371 stack (370 head + 301 18" cab) and had never tried that head with any other cabinets. Well 3 weeks ago I won a SWR Big Bertha (2-15 + horn) on ebay, wasn't really sure what I was going to with it (Get another SWR amp or what) , I already had an old 240 watt Redhead & Goliath jr III (2-10 +horn). I didn't really like the Redhead/Big Bertha combination. So I took the 370 amp & Big Bertha (4 ohm)& Goliath jr(8 ohm) and plugged them all together. I'm in love. I should add that I played Bass many years ago and I've been playing guitar mainly since 1973 and I bought that Acoustic Rig for the "house Bass system" for whenever Bass players would come by my house to jam, so I hadn't really played that amp much. Well all that has changed now. What a sound! I'm playing Bass in a brand new band and used to have a large SWR Rig ,but sold or traded most of my Bass gear when I couldn't get a gig. (Didn't mean to ramble) I'm new to this forum but hardly a newbie.
