I use a K&K Sound Double Big Twin pick up through a Fishman Plat Pro, an AI Clarus and Ten 2Ex cab. The sound works for me and, recording, I try everything; mic, pick-up with pre-amp, with amp. di etc and the one thing I have learned is that all the kit in the world won't make your bass sound like it doesn't!! An Antoni 1/2 size isn't EVER going to sound like John Patitucci's Thomas Martin bass or Charlie Haden's Vuillaume. If you are not cutting through the mix, it may be that the sound you have is not as rich as it needs to be? Try another mic a little further away from the bass to put some 'air' in your sound. With a DI, close mic and ambient mic, you will get what you are playing. If that doesn't work go back to the sound itself.
