None of these old classic amps is going to get any MORE common. A few will become lost to us every year, whether by destruction-by-modification, house fire, fire at the gig where the amp was left overnight, or tossed in the trash by elderly parents who have absolutely no clue that sonny boy's old guitar amp has substantial value.
.........stuff removed.........
I once, in the mid 80s, bought a silverface Fender Champ at a pawn shop for 75 bucks. And I never thought it'd have ever been worth more than that.
Well...as an investment it would have grown more in relative value than any other amp I've ever owned. I've seen them go for 600 and more. Which I think is silly, because
their tone is absolutely nothing to write home about.
Elderly parents? More like our kids know it’s worth something so they sell it at the first pawnshop for 10% when we are too senile to argue.
Also, those black/silver champs sounds pretty good into an old Celestion. But how good? I swear I saw a pretty 65 vibrochamp sell for $900 in 24 hours Just a month ago. Crazy.
