You can use this proven design for inspiration - an Ampeg B15n Portaflex bass amp.I want to create a tube pre-amp with a baxandall EQ. I've searched bits and pieces and came up with this design.
If you want to feed an existing high-impedance instrument amp, the preamp is sufficient, if you want to play into a console or interface (or even lower impedances), you need a driver output, possibly a tube cathode follower with or without output transformer. Solid state is of course also possible.
Edit: Ampeg, not Apogee
