Yamaha have always been good, but I think since the BB424 and that series they seem to both be focusing on the BB range and absolutely knocking it out the park in terms of quality at each price point. The X range helped them look a bit more trad and bling at the same time widening their appeal.
so suddenly Yamaha BB are in and good again and if you can’t afford £2k for the Japanese made BB2024 It kinda makes sense that the older ones would be of more interest.
