I have a recital in a few days and a speaker on my GK Neo 4x10 cabinet appears to have blown. I’m getting distorted sound out of the amp no matter what. I’m trying to think of a good substitute for the GK Neo 4x10. One friend offered up their Ampeg, another their Eden 4x10, another offered a Peavey, and another friend offered up a GK Neo 4x12. Any suggestions would be highly appreciated!
