Hi to the Marshaller!!!
I have an 8 years-old JTM30 series amp. The first 4 years used 8 times/month, the latter 4 years not used.
Always perfect sound, never had problem.
Now after 8 years: the clean sound is perfect, but the distorted sound is horrible, the gain at 100% seems to reach the old 50%, and it is unusable.
If I connect a boss ds2 pedal on the clean channel the sound is the same.
I tried to exchange the three preamps tubes but nothing.
Help me please.
