OK, I'm a drummer.....(but I do play bass as well). I'm searching for a solution that will attenuate my bass players low frequencies (for live small club use) on a wood stage. I'd like to know if anyone has used the Auralex Gramma V2, and found it to focus the bass sound and alleviate the "mud", and extremely low end frequencies that tend to build up on a wood stage. Problem is, we both setup in a corner, and that's the worst place because the low end and standing waves accumulate and it's killing me. No alternative setup is available, and we play pretty loud. Any suggestions would be greatly appreciated!
