Tank like DI
I've had this DI for at least 20 years, yes twenty years. Sounds great, works perfect, I've never had a repair.
Only gripe would be that "some" XLR's won't lock into the whirlwind male XLR connectors for some reason. I don't really know why, but that small flaw doesn't ruin this box.
I wouldn't be surprised if this DI outlast my lifetime.
