My big rig is an F2-B into a Carvin DCM200L into two 1 x 12 cabs, each with a JBL K120, one of which was re-coned in hemp by John Harrison at A Brown Soun/Tone Tubby before he passed away. The hemp JBL sounds great, but is just a little darker sounding than the stock JBL. I adjust one channel of the F2-B to accentuate the highs and the other to accentuate the lows. The low side goes into the Hemp JBL. Together they sound great, but these days I'm using the Quilter more and more. It sounds 95% as good as the big rig and the convenience is worth the trade off for the 5% difference, IMHO. I don't think anyone in the audience notices the difference, anyway.
