My hair is as long as Ricky's and I am past 50 or so.
50 or so what? (FWIW I'm past 60 with about 1/2 that hair length, but solid chrome)
Obligatory Marshall content: I'm following this thread with interest, thanks for the work Ricky. I jumped in and went the distance getting the 2555X head for under $1K, then followed up with the cabs making a full stack. Total overkill, but totally satisfied.
