Low pass filter to be placed at amp's direct out?

Man...it doesn't say anything about that in the manual and then there it is in the block diagram! I'd be p#$$ed off if I bought one and then found that hidden in the schematic without mention of it in the rest of the manual!

Interestingly, most people that use cabsim's do so to make the drive and high end LESS fizzy.

Yeah, hence my conundrum!

Sometimes a pedal DI is going to send a better signal to FOH than an amp’s DI. They might have higher quality components, or a (better) DI, or have cleaner gain staging. That said, I thought that the Rumble’s DI & cabsim were supposed to be at the least functional.

Maybe a LPF between the Amp DI and FOH?

I think they are functional. I think honestly it’s sending a signal similar to what it would sound like with the tweeter, and I don’t use the tweeter.
