I had a screwhead years ago do that to a fried LE5-5 speaker that was in one of my L-65 Jubals. I still have that speaker as a spare.

I only knew I didn't like the un-original, stuck out like a sore thumb look, didn't think that it might also be altering sonic characteristics of the speaker.

I luckily sourced an unmolested replacement LE5-5 from the auction site and all was well.
