I still don't get the amps name vs cameron thing
chupacabra is a folkloric creature that feeds on cattles blood
chupacabra literally means GOATSUCKER in spanish and portuguese
is Mark Cameron's nickname goat or something?
cause THAT would be funny
any experient guy could easily come up with amp with all those features and that is voiced pretty much like a Cameron without never having played or seen his circuits
both Cameron Jose and Fortin Cali are heavily based on the Arredondo mods, and that ain't no secret
I can even figure out that Ceriatone myself
there are many possible features that could be called "era switch" that would change the entire response of an amp with only one switch and no relays
a bigger cathode capacitor wired to a switch or some negative feedback tweaker
but according to Nik, it messes with the Master, so it's probably just the Jose master switching (pre-tonestack diode clipped master vs regular non-clipped post-tonestack master)
both Cameron and Fortin use that feature (and apparently Dave Friedman's saturation switch)
even the Peavey VTM has a switchable diode clipped tonestack/master in a very similar way the Jose master is wired
bright switches are used by Fender for 60 years and they can be wired in many preamp spots and with different values... or even as a power amp presence mod, or a reversed treble cut in the phase inverter
probably just a 3 position bright switch with 2 cap values (or no cap at all) in the gain pot (like a XTC) and another one after the second stage
focus is somekind of midrange voicing switch, so it could be a cathode cap mid boost/bass cut or some serial bass filtering
even the guys at Bugera could think that by themselves
of course this is pure speculation, but if even I can come up with those VERY SIMPLE ideas (I can't solder a fuckin wire), how come Nik can't?
why would he bother buying an expensive Cameron and having to scratch out all that epoxy crap just to copy OBVIOUS features?
from the clips, the amp doesn't even sound anything like a Cameron
I doubt it has any of Mark's personal tricks
