I'd like some advice about upgrading the speaker and tubes in my used Tweaker 40 combo I just bought. I love the overall tone but when the tubes warm up, they get pretty muddy sounding. Probably just old, but I've never owned an amp with 6L6's before, so any advice on what brand and flavor would be great. This combo has the stock Celestion GH50 that is okay but I'd like to go for an upgrade. Maybe a speaker that doesn't break up so easily too? I play mostly rock with an edge (Foo Fighters type of stuff.) Guitar is a custom Don Grosh, mahogany body/maple top/maple-rosewood neck/DiMarzio PAF in the bridge.
