Better made I'd say. T-40's are 6lb of timber with another 6lb of metal bolted on 😱
@Pow_22's bass is definitely a Unity, they got some " best bass " award from Bass Player magazine 🙂
The Dynabass was a bolt on active with 2 single coils, Dynabass/Unity series was a neck through active PJ.
Going L to R. Dyna/Unity, Dyna and then Unity.
To confuse matters these were also sold in the UK as Dynabass/ International Series.
