Yeah but if ‘market research’ or player feedback was showing that it wasn’t delivering a tangible difference then all that cost, expense etc would only make it prohibitive and like you point out not worth translating to a higher priced bass for a non perceivable ‘benefit’
As you know I like that Yamaha innovations make it into their lower priced models as done with the angled six bolt neck fitting previously only found in higher end artist models and the sandwich design in the 734/735. But I think we’re a bit off vibration treatment across the entire range just yet.
