Thanks for the suggestion. I was also interested in one of those but it's outside my budget.
I've been on a quest for very light a shortscale for several years since the stroke and, this time, what I did was use the short scale neck (25.5" scale) from a Glarry bass that was on sale of $60, designed and built a hollow body using a paulownia frame, top and back plates from lightweight laminated floor underlayment from Home Depot, a DIY stick bridge, the bridge plate of the Glarry for a string anchor, a single inexpensive humbucking pickup from Amazon wired straight to an Electrosocket from an old project, and a set of Gotoh GB350 Res-O-Lite tuners form the same old project. That bass weighs 3lbs, 7 oz. using my fishing scale. It's still a work in progress but it sounds very good with nylon tapes and is very easy for me to play.
If the Fallout weighed less I probably would have bought one of the imports.
I know this is almost a derailment… but the lightest I’ve played were Hofners. Aside from that I think the Ibanez AGB200 can sometimes come in light. Oh! And Kala has a mini solid body that sounds good on video. To keep from derailing, drop in to the TB short scale club and see what else people say.
edit: all of those were cheaper suggestions.
