Hi there, recently I was quite concerned about a rather bad, quite thin sounding overdrive channel on my Hot Rod (the former model)
I had focussed on the input tube (V1) and of course, the power tubes -obviously the clean sound hasn`t been affected.. My local dealer advised me to check the other preamp tube, the second one (V2?) caused my suspicion, as it rattled a bit when touched, and actually I tried a GrooveTubes 12AX-7M that I had as a spare one - I`m not sure if it`s really suitable, but I think I noticed quite a sound difference!
Any advices or hints about that? Thanks a lot from Germany!
