I'll take the Captor X to the testing room on Monday and try to see if anything will change. I will keep you updated! Thanks so much! Your info was really helpful to me.
Meanwhile thanks for your answers, yes, if I touch the strings with my hand the feedback stops. as soon as I lift my hand it starts again. At home I use a captor X, could it be enough to solve the feedback problem?
Sire L7
Seymour Duncan Slash Alnico pro 2
Marshall 1960 4x12
hi channel at 9. low chanel at 12, i'm 3 meters away from cab
all cables are Roland
i've the same problem in this configuration.
Presence at 12 o'clock, high channel volume at 9 o'clock, low channel volume at 12 o'clock.. I am positioned about 3 meters from the cabinet on the side
it happens when I turn up the volume of the guitar, both with the neck pick up and the bridge pick up. I tried to move, walk away, but it doesn't change. Excuse my ignorance, what does non mv amp mean?
I had problems with my head, a Marshall SV20h, the head goes into feedback immediately. I use jump channels. I tried replacing the preamp tubes, but the problem persists. When I use an overdrive the feedback increases dramatically. What could it be?
