Thanks for the replies I guess. Buying all new gear is out of the question. I'm retired and spending lots of money on new equipment is not in the budget. Some of my guitars are almost 40 years old. The TLM, pre amp and processor are more than 15 years old. I was hoping for suggestions that focused on EQ settings, gear setting, mic positioning, and overall approach. I have methods that I've used in the past. I thought I might get some different ideas in these areas. It seems to me that the TLM sounds different going into the Xair 18 and Reaper than it did going through the VS 1680, even though I'm using the same outboard equipment.

EQ is EQ. There's little I can tell you that you can't figure out better,
but in the past I have run a duplicate/parallel of my track, aggressively eqd (usually highs down), and heavily compressed it.
That, alone, sounds squashed and dull, of course, but dialling it in with the original can beef things up nicely.
Also, you might play with mic placement, particularly rotating the mic so it's off-axis slightly.
Pop the headphones on and experiment. Whether it's acoustic or amp you can get a huge range of tone just from minute adjustments in position (L,R,U,D) and axis rotation.
For vocal the axis thing can be useful but, also, the difference between putting the mic forehead height and pointing down, compared to chin height pointed up, can be huge!
