My plan is to pick up a vintage M-85 at some point to play through the Thunderbass w/cab I plan to pick up this weekend, but in the meantime I mostly play a ‘78 Musicman through a mid-70s Ampeg B25b with an Ampeg 4x10 cab. Sometimes I run a ‘64 Bassman head through a 2X12 cab in series with the B25, or I just go with my ‘08 Fender American Standard Precision Bass 5 through mid ‘70s Bassman 100 with a matching 2X15 cab. Sweet tone all the way around, but I’m ready to explore the Guild bass sound.
