Well, I have done a complete swap out of my home bass system and I think I have found the sound. I have always wanted an all tube system for home use. I already have a Fender Musicmaster Bass combo, but I use it for guitar. I found an Ampeg SB-12 head in the local classifieds. I had just recently heard a friend's B-15 and it sounded amazing. I got GAS. I checked out the SB-12 and it was in killer shape. It sounded nice and I was giving it that look. I bought it and gave it a nice cleaning. Now I needed a cab to go with it. I found a Bag End S15-B used at a local GC. Research here praises this cab and once it is dialed in, so do I. Together, it sounds amazing and I can get lots of killer sounds. It also kills for guitar! I used this setup to record new tracks and it gets that thick sound that is creamy and nice. I had to do some quick selling of my WM's 10 and extension, but that was pretty easy. I did some serious driving, probably 2-300 miles to get all the deals done. Until I find the appropriate cab, an original Ampeg, I have one serious rig for recording and practice. The Bag End is also small enough to pair with my Mesa Scout for a tiny rig of terror! Anyone seen a SB-12 cabinet out there? Any thought on the pairing of Ampeg and Bag End?
