Hi all...iv got one of those tdk head demagnetizers but no instructions....does anyone know how long you use it for

If it's one that's a cassette with a bunch of electronics in it that's powered by a button cell then you just put it in and press play for a couple of seconds. If it has an LED this will flash and then go off, meaning it's all done.

Make sure your volume is set to ZERO lest your head be partially or entirely exploded, however.



Rock On.

Thanks alot duuuude.................great
