I use a butane lighter to burn the insulation off, followed by a light
abrasion by pulling the end from a folded fine sandpaper (600 grit
silicon carbide). Then it can easily be tinned.

I would solder to a pair of flexible lead wires that are anchored to
the coil with tape.

You might start with a variable resistor soldered to the lead wires.
That makes adjustment very easy. Once you have found the desired
response, select a standard resistor with about that value, to replace
the adjustable. You can connect that final resistor to the terminals
on the jack that the lead wires terminate on.
