Well, I guess I'll throw in my 2 cents worth (I always do). I like your
original idea of the triple preamp. I the inputs that accomodate the
various inmput levels are great. Distortion... Well, OK. So, If I
understand this, we are still talking about a 1U module with two clean
channels, one for guitar levels and one for synth / line levels? Then the
distortion unit could be patched into either (or neither) ?? Next question
from the clearly uninformed... Can a front panel switch be used to change
the input level of the preamps? Does that put too much on the panels? Or,
could the preamps be "user configurable" so they could be built as one of
each level or both one or the other? Or, could there be a trimmer (on the
board to trim for either level input) so that each could be adjusted to the
gain choice of the user and changed when he changed his mind?
These are not suggestions for change, only questions to dig out the
options. Some users might never use the guitar level input and would like
the two synth levels. Some users might like two guitar inputs so one could
be clean and one patched with the distortion and use a MOTM-700 to select
which one to connect the guitar to (now that is a fancy A/B switch).
Anyhows. Build it and they will buy (I know I will).
