This is a recording of me playing through my laney 15 watt tube combo. Recently its started making this hissing staticy noise. I sprayed everything down with contact cleaner (jacks, tube pins) and it went away, but tonight came back with a vengeance. I'm playing though a humbucker equipped lp style guitar. Everything stock. playing through a decent cable too. dont mind the playing its just a chord profession (I'm slightly out of tune as well.
