Oh THAT is a really sexy looking bass!
I thought that Sandberg simply made good basses, but after being forced by circumstances to try a few (honestly, I didn't want to! ) and eventually buy a VM4, I'm saying that these basses are pretty special. The build is superb. I was not in love with the preamp in mine (I didn't specify anything and went with the stock one to start), maybe I'm a little picky, but it is a fabulous bass regardless. If the 'basics' are good, and they are VERY good, then it's very simple to modify any bits you'd like different. It's just hard to say what to change when you order a bass, as you can't try it before you buy.
In case it sounds like the bass wasn't that good... I've pretty much gigged with it exclusively (a few gigs with the Stingray, but >90% were with the Sandberg) since I bought it without any modification. It's still in my to-do list to remove the preamp and have it set fully passive (I like passive tone controls) and probably use a Tonestyler in it. The forced lockdown might just be the time I needed for it, however with one of my bands we're doing a lot of "remote song writing" recording etc and I keep using it... It's just soooo nice to play.
