But yet somehow that little MXR still sounds good. Whatever design, a
good, err... no GREAT, phaser should be part of the MOTM plan. :) See
what you got started again Thomas?? Now, back to pre-amps...

Boo... Hiss... Come on Paul.... Can't we have just one mic input, say XLR,
balanced, low impedance. That would cover most everything. Phantom power
guys can handle their own power (or a spiffy phantom power jumper on the
MOTM circuit board). Or, you could go 1/4" high impedance and force the
mic guys to use a matching transformer. BUT, all good mics are balanced
low-Z anyhow, so .... Of course, to keep the MOTM 1/4 input appearance, I
guess any low-Z mic input should be a stereo jack and not a real XLR.

Yes, but life isn't fair and the guitar layers get all the great chicks.
So..... How about 3 inputs (like the original). One optimized for guitar,
one for line levels, and one with a user adjustable trim (or appropriate
component change on the circuit board). Or a switch on the 3rd pre input
for low level / high level inputs. Am I missing someting, or would not a
guitar input and microphone input have roughly the same gain required, if a
microphone matching transformer was used to come closer to the high
impedance input of the guitar input (or the trimmable). I know the
impedance of a guitar is higher than the high impedance side of a
microphone transformer, but aren't they close enough? So channel three
could have two inputs, one balanced low-z and one unbalanced high-z. (I
know, I am thinking mixers again).
And then there is that distortion issue.... Separate module? Or maybe the
triple preamp could be two flavors:
# 1 - dual input with the distortion Paul suggested. (this is the guitar
MOTM interface) one of the inputs for guitar and the other ???
# 2 - triple input, no distrotion, two line levels and one mic level (synth
MOTM interface).
See, then we would have to buy them both.
I've rambled long enough. I love this list and hearing what others think
is important for thier MOTM systems. I wish more of you quiet types would
speak up. I see you out there lurking.
And thanks again Paul for letting customers in on the design issues. I
think that a lot of good ideas (and much controversy <grin>) have come from
the open discussion. I am always happy to see the final product even if I
know it is not "exactly" how I would have asked for it because it has the
input of so many knowledgeable folks and Paul's good sense to separate the
good ideas from the bad.
