Hey
I've had this Marshall JTM60 combo from new, and have never been able to rely on it. Currently the amp is not only producing the fundamental tone from my guitar, but in addition a dissonant tone which is lower than the fundamental. This was originally only when using humbucker equipped LP, but now my Tele is affected as well. The tone is most noticeable on a G string twelth fret (or maybe I just notice it more there). It has the wonky effects loop problem, which I fix with judicious use of a jack cable. All the tubes have been replaced within the last year, and its seen plenty of repair shops over the years. I've also seen some advice on the web which says this is just a bad amp design and not worth bothering with. Any advice would be welcome!
Cheers
Owen
