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.
