In the continuing saga of my not being happy with the sound of my SLO anymore.
Its currently got a set of JJ 6L6GC in there, which tested good toward the end of last year when I had it in to check a funky bias that turned out to be the bias meter.
They gave it a general Once over and said it was fine.
But I think there's something weird going on with it. OD channel Sounds a bit lifeless to me, with a weird almost mildly comb filtered thing going on in the midrange, splashy/scratchy might be a good overall description.
I've changed all my preamp tubes out one at a time and no dramatic difference, so it's not a preamp tube.
Just wondering before I end up sending it in for a full check against a schematic.

Sorry, should have mentioned, they were checked on an actual tube tester, and not one if the Orange ones, an Avo VCM MKIII
In fact, for guitar amp valves a 'proper' tester is almost useless other than for matching - it will tell you if the valve is definitely no good, but not if it's noisy, microphonic, poor-sounding or likely to fail when subjected to the sort of stress in a real amp.

Grand, so the power tubes could explain the perceived lacklustre sound? I'll order a new set of 5881s. Never did like those JJs anyway.
