I have not had to remove turns, but I wondered why a bit of insulation could not be scraped or burned off and several turns shorted along the top edge of the coil.
Don,

I've never tried that because those that know say shorted turns on a core will make it useless.

A way I use is to unsolder one end, unwrap a turn or two and reconnect. The loop outside the core will have very little inductance so trials can be done quickly and restored if the required effect is not achieved.
