Trying to decide if this is my ears or actually a possible issue. Got a used 57 Custom Champ and it only sounds right to me if I run an EQ pedal with a fair amount of high end added... according to the pedal it looks like at least 5db around 3k with a fairly wide bandwidth. If I plug the same signal into any of my other amps with their tone controls neutral it's way too bright. The Champ sounds great like this but it seems like it shouldn't be necessary. Is this just the way it is, or is there a possible tube or component issue that I should look at? I have the day at home today and would love to chase this down if anyone can give me advice on where to look.
