Generally, that's complete nonsense. That's a myth from the 70's when people were trying to justify their ridiculous 11 lbs Les Pauls.Generally, less mass=less sustain. Strandberg is one of the lowest mass form factors I can think of as far as guitars go.
More rigidity = more sustain. Anything that robs energy from the string vibrating decreases the sustain: the neck or neck joint flexing, fret buzz, pickups that are too high, a bad contact point or loose bridge saddle, etc. The wood at the tail end of the guitar isn't going to have a measurable effect on the sustain.
I bolded fret buzz because that's common with bad store setups and it's easily fixable.
