Maybe my Google is just not working out but I'm surprised I'm not finding more options for the '67 Bassman.
Mike Ness uses a '67 Bassman apparently initially modded by "Billy Zoom" and then later (again, so I read) by /13. No idea what said mods do - other than it's not a standards '67 Bassman he famously uses.
The lion's share of his tone is the amp (only has a boost in front and virtually no pedalboard) so it sounds like an amp that would be very fun to experiment with on the Kemper.
The only commercial profile I'm really finding for the '67 Bassman is MBritt's "67 Lowman" - which might be good but in the Soundcloud demos the closest he gets to gain is a runthrough of "You Shook Me" (Bassman seems an odd choice for AC/DC but I digress). In any case I can't tell if it's a platform to get to a Social Distortion sound or not ...
Anyone have any experience with that profile or other recommendations? Thanks!
