Had a bad cap after years of service. It slowly lost it's great sound and gained a hum. Now it's back to it's lovely self. I may consider that scoopless mod. But as is it's the best.
I've been through speaker changes as my Bag Ends failed, to be replaced by Celestions to be replaced by long throw LDSs. All three had their own rich characteristics.
So, take it to a good tech.
