I needed to buckle down and save for one years ago. That said, the Carvin stays. I would not be surprised if I end up liking my SB5000 more than the Sadowsky, once I get it.
I forgot you had that carvin. Those basses are super cool. Total gospel machines.
If i was you i would look for a 5 string sadowksy metro p/j. That may blow your mind. They are incredible. Then you have that and the carvin and you are set.
