He is also incorrect with respect the pin position on the recent Novoselic RD.
Apart from RDs, Ed obviously either hasn't checked the strap pin position on recent Gibson TBirds or has chosen to ignore it. One would think the recent TBirds or Novoselic RDS are the competition for the bass he is reviewing rather than vintage TBirds, given pricing- although the price of brand new T Birds is another discussion. It is not surprising that the mere mention of a Gibson bass in some places is guaranteed to bring forth a tirade of misinformation with this sort of nonsense circulating.
My RDs and my 09 Bird behave exactly the same way on a strap as the Delgada in the clip. The RDs are very stable- their bodies would be significantly heavier than the Delgada, I would expect.
His misinformation is provided in a way that infers a significant advantage to the bass he is reviewing, which is simply not there.
