Nope, the bypass tone is different, and these are both true bypass so there's no reason the bypass tone should be different. the difference was somewhere else, either in my bass onboard EQ or in the IR's EQ. Also the tubes see the same voltage on the plates (200V or so) regardless of input voltage, the X series just uses a 12V input because it's a lot easier to heat a a 12AX7 with 12V @ 150mA than 6V @ 300mA.I wonder if the 9V - 12V difference in power supply voltage has anything to do with it?
I like the difference myself. Folks who would like to mitigate the brightness/punchiness of the X might roll the 12AX7 for a 12AT7 or even a 12AY7.
As for the re-do of the demos I have to apologize for the delay, I got the boards put together last night and got pots attached but haven't installed tubes yet, I've been busy helping my wife remodel the pantry
