I have a Mann M100 PAR pa amp that looks like a Garnet G100PAR-M100TAR.It is fully working and the tubes checked out ok.I would like to convert it into a guitar amp for my daughter.She is learning to play a Godin 5th Avenue CW Kingpin II Cutaway.I would like it to have different sounds,from clean to ?Any suggestions to make this possible would be welcome.I have some tube electronics training but have not been doing much of that for many years,
