They are not the same. I had an '80 Sabre and a '91 L-2000 and the Sabre was way more to my liking; powerful, aggressive tone and a slim neck. The L-2000 sounded fine, but it seemed weak and muted compared to the Sabre. Also, I disliked the fat, slow neck on that thing; My friend had a '94 L-2000 with the thin neck and it was pretty awesome, and the playability of it actually made it easier to get a more aggressive tone out of it, but still the Sabre was my favorite.
