Currently my rig is a Custom Verellen MeatSmoke (200 watts and more superbass-like OD channel. Goes to 2ohm) and a Flatback Ampeg 8x10. It is the best sounding bass amp/cab combination I have ever played. But.....I play in a three-piece with the loudest drummer ever and a guitarist with a 100 JMP, Orange OR50 and 2 4x12s.....the flatback is very very inefficient. On stage, I can barely hear myself and only if the soundguy is top notch. I play with the Verellen dimed. And use the OD channel like a fuzz. Let's pretend that money is not an object (I can save, sell other gear, etc) Also I have a Marshall 1982B with Emi 2512s. Sounds really "Lemmy" but as expected doesn't have the lows I want. But would be happy to pair with a solid bass cab. (4 or 16Ohms) Here is my list of options: (amp isn't going anywhere, it is definitely loud enough) 1. A second flatback. Will this be any louder? 2. Add any neutral cab to augment the 4x12: Fearful 15/6, Barefaced Super Twin, etc 3. One cab to rule them all: Berg NV610 or NV215, Greenboy Dually, custom cab or your advice. I prefer to go lightweight. I'm 40 with a bad back. No tweeters. Happy to hear ideas. Thanks in advance.
