The BSR was a Smith model before it was used on the Burner series Basses. The BT shape was used first for the Burners by copying a BT Custom in Japan back in 1989. It was about 1998 when we started using the BSR shape on the Burner series. BSR 'B' meant it was a Burner using the BSR body shape. WE had already been using this shape on our handmade Basses for several years by that time.
