I just received my Ecstasy module a few days ago, and I'm a little confused on the front panel switches. I think I now understand how the bright switch works (manual is WRONG!). But I'm not totally clear on the Schizo switch. I know a little from asking questions elsewhere, but I have yet to connect all of the dots.
The manual says it's supposed to loosely represent three decades: '70s, '80s. and '90s. In my mind, that kind of means JTM Plexi, JMP Plexi and JCM 800.
That said, the switch is labeled M, V and C, top to bottom. I'm fairly certain I've read M=Modern and V=Vintage. I'm not sure what C means. Classic? Custom? It stands to reason that modern would be the most recent decade, so M should be Modern and JCM. I guess...
From what I've read about how the switch works, it does two things.
1) It removes a 100K resister and 0.1uF cap from ground, to create a boost for ONLY the M mode.
2) It puts a 470K resistor in parallel with the existing 4.7K resistor (resulting in a 2.4K resistor) to increase overall gain for BOTH the M modes and the V modes. So only the C mode has the 4.7K resistor
So overall
M - boost on, 2.4K
V - boost off, 2.4K
C - boost off, 4.7k
The M has the most boost and gain. The C has the least of both.
I can't wrap my brain around this. If the C is classic, I'm thinking that chronologically falls between Vintage '60s and Modern '80s. But I don't think of '70s Marshall amps as being lower gain than '60s amps.
What am I not understanding?
