You may need service bulletin #5 from Music Man. It is about RF INTERFERENCE MODIFICATIONS. If you have a fax #, email me and I will send it to you. It may help. All though it does not talk about tremolo interference it does talk about the reverb and Pc board interference.
You may have a bad tremolo 2N4091 intensity or 2N3391 speed transistor that is picking up the [RF] interference? If what Steve has
suggested helps then go in that direction.
