Marshall Impedance Switch

[drewl]

Hey all,
Anyone know if the new style Impedance Switch fits in the hole of the old style plug in ones?

Been a while since I replaced one, don't want to hack up this 70's Superlead.
Thanks

The ones from Marshall are slightly larger than the old type and the hole in the chassis needs to be opened out.

That's what I thought
Thanks
