I still haven't reviewed my SLB300 yet, because I'm too busy playing it! But here's a post on the tweaks I've made, which as far as I'm concerned tipped it from being an intriguing novelty into a genuine workhorse instrument.
First of all, I purchased the
extension frame, which fits the 200 models as well. Keeps it from twisting away and deepens the pivot point against your body, getting it closer to double bass ergonomics. I bought mine on Ebay for about a hundred bucks.

Getting there! But I was still frustrated with what I've found to be a common problem with electric uprights: the tuners. They're almost always glorified electric bass tuners, and the ones on the SLBs are no exception. You're never getting the fine control over the string length and tension that upright tuners are designed for. So I bought a set of
Roth & Junius Deluxe Machines from Thomann, hoping I could just swap out the old tuners and drop them in.

Well no, I couldn't. It was going to take some reaming and shimming, as I discovered when I put it in the extremely capable hands of
Matt Bohn, The Bass Doctor, who has his workshop in the hills above Santa Cruz, California. If you live within a 200-mile radius of the guy, I'd consider it worth the trip.
Matt carefully considered their placement and position, because the SLB peghead is small and crowded. But he figured it out, and I couldn't be happier with the result.

Not only do they tune beautifully (and look beautiful), their extra mass makes the SLB
feel more like an acoustic upright under your fingers. There's a presence, a heft, that was otherwise missing. Still fits in the carrying case just fine.
Seriously, one of my least-regretted purchases in a long while. Combined with the extension frame, it's a significant upgrade in look, feel, and playability. 10/10 would recommend.
