Peavey rage 158 transtube series 15watt been stored away since the 2000s no need for it there blue tack unfortunately on the front cover / material back in the day I liked the old school peavey logo so I stuck one on there but since fell off and I been trying to pick it off for ages marks and wear from storage tested works well I think the setting from vintage to modern mode was a gimmick it hardly makes a difference that I can tell but I was testing it at super low level probably why I had the odd crackle when turning some Knobs from its age from just sitting there seemed to be better or cleared after a few turns but bare that in mind apparently contact cleaner into the pots would stop that you get it with guitar volume and tone knobs over time from dust and dirt etc
