..... this one goes to 12.
So I guess we've come full-circle. Now it seems more common to refer to amp settings as they would appear on the fact of a clock, rather than their actual pointer settings (since those can vary, i.e. the tweeds above). So it's more common to say "I set my treble to 1:00" rather than "I set my treble at 6 - or would that be 7 on a tweed amp"? Mesa even refers to o'clock settings in their manuals, it has become to common.But why did older amps "go to 12"? My understanding - and I will happily be corrected by more authoritative information - was that legending of rotary controls had a tradition of being guided by military and nautical descriptors, which were, in turn, analog-clock inspired. So, setting something to 12:00 meant straight ahead, and 6:00 was directly behind you. We still talk about control-settings in that way, but the legending on chassis more closely corresponded to that. When I lived in Victoria, Capitol Iron Hardware carried a lot of surplus marine gear, from CFB Esquimault and other places, and a lot of it had controls that "went to 12".
