So much potential with the flexibility appreciated

This bass has been a game changer for me, though it's taking a bit of adjustment. I play primarily upright bass and I play with a bow. With this instrument I've been able to put in a lot more practice, it's easier to record, and it takes up a ton less space. The shorter scale length is more noticeable than expected (it's 34" like an electric bass), but it converts easily once you work on your hand spacing a little. Heavier strings are a must, and the attached recording is early on, right after changing to Fender flatwound .055-.105s. The gauge makes all the difference when bowing. The recording is playing through a Fender Rumble 40 with a touch of reverb from a Walrus Fathom.

There was an issue with the first instrument I was sent and, upon mentioning it to my sales rep (thanks Ed!) he got me over to support and they sent me out a new one next day, no questions. Support has been astounding and that's why I shop at Sweetwater.

Don't sit on the fence for years like I did, if you're thinking this will help with your practice or recording just get it!

This is an excellent instrument. Well made. It's doesn't sound exactly like an acoustic upright, but it's very easy to play, and has its own tonal character, that sounds really nice. I think you can use foam, or nylon coated strings to make it sound more like an upright. A perfect addition to any bass arsenal.

I am a P-Bass guy and thought I'd like to try upright bass. I bought this bass and It seemed to fit naturally. The length of the fretboard is similar to a standard bass although wider and thicker. After practicing with for about an hour, I opted to take It to a gig relatively untested. I ended up playing It for the whole four hour show. Everyone loved the sound and the upright look added a bit of character to the band. The tone is thick, full and distinctive. If you are thinking about doing It, this bass is a keeper.

I love this bass!!! I'm primarily a keyboardist and the tone of this bass is perfect for my home studio recordings.
