So essentially Dav I could do the same thing using my Rumble 75Combo LINE OUT and using its EQ section into my Rumble 500Combo Effects Return without any ill effect...so to speak?? The Rumble 75C has that wonderful 12" Fender Special Design Driver in it and always sounds great if I use the 75 combo anywhere.
The Rumble 75 EQ has all the same controls (bass, low mid, high mid, treble) except for the voicing buttons (bright, contour, vintage) although it does have 2 Mid Scoop shape buttons. The 75 even has the same type of overdrive control (gain/blend (75) instead of drive/level controls (500)). I have never tried running the 500C through the 75C because the 75 doesnt have any effects send/return jacks so have always been reluctant to use its Line Out jack into another amps effects return, so Dav what your advocating is a safe thing to try out then? Thought I'd ask first cause I hate the sight of blue smoke and the smell of Kentucky fried circuits lolll
