Hi Guys,
Im having some trouble with the lead channel on my Mrk IV. When I turn on the lead channel, the volume fluctuates up and down for an amount of time, from really loud back to its original volume setting...after a while it calms down but the odd day it can really act up!! Im wondering is it a tube problem or does it need a full service..im just worried because ill be gigging it soon and I could do without such a problem especially on the most important channel to me!!!
Any help would be really appreciated...
thanks,
Killian
