Hello, I've been playing the bass for about 4 months now. I'm looking at a new bass because the one I was renting was way overpriced, a cheap used laminate that wasn't that great for $3000. I'm looking for something in that price point, around $3000. I'm deciding between one of the Shen basses at the Bass Violin Shop. What would be the difference between a "cheap" one like an SB80 (laminate) versus something like an SB150 or SB180 (hybrid) or a carved one like the SB200 Willow (carved)? SB190 seems pretty nice too, but it's a little pricey. If it's way better then i'll consider it. How much more maintenance would a carved bass need than a hybrid? The shop is a couple hours away from where I live, would prefer not to have to go there extremely often. For the SB150, what's the difference between the oil finish and the lacquer finish? And what is that mid-century german 3/4 bass?
