Myself I've got a Bag End Q10B-X, it's a fantastic cab. It's the shallow 4.10" version. Sometimes I'd wish for a little bit of more 'embedding' of the low region. I play a fivestring jazz custom bass with a low-B. I'm playing with the idea of adding a GS112 or similar cab to it. the GS112 is just a bit smaller then the Q10, so it fits perfectly on top of it. What would you guys think of it?
