You could try a valve preamp/OD pedal into a light power amp or the FX return of a small head.
BK Butler blue Tube
Mesa boogie V Twin
EBS valve drive
Myco Various on low gain
Dave Hall various pedals
Noble (bloody expensive)
there Are many more and some are not manufactured now, but all are available secondhand without much trouble cheaply enough except the Noble.
If you don’t like what you hear, sell it on and try another flavour easy enough with no loss to your pocket.
Then that opens the world of tube rolling’ up to you 🤣😄
