Hi, I've been playing electric bass for a while now, and have gotten pretty good at it. I've been wanting to get an upright bass to start playing. Can an upright be both electric and acoustic, like a normal acoustic/electric bass? Also what are some good upright basses, I know they are expensive and am willing to pay 1000+ for one. Any good brands(preferably under 1000 or not much over.) to lead me in the right direction? Any advice is appreciated. Thanks.
