My prediction that EHB’s would be widely available, for fairly cheap, on the used market, has not proved out. They do look like a great mod platform, and the very light weight, compact design is attractive.
I’m still prowling the classifieds, like I need another bass or a project…
As far as four string Dingwalls go, I love the longscales. The lowest string might be 36.25 instead of 37, but I can’t tell the difference tuned E-G. Maybe for a B or lower tuning, it might be a deal breaker, but where else would you get even 36.25. And the fours tend to be super light weight. My AB four string is just 7.5 lb. And many string sets will just make it on the E for length.
