How do you guys feel about running a preamp pedal through the return jack (without the send jack) on the effects loop? Do you feel like you lose some of the rumble's magic, or can you still get a good clean rumble tone? In other words what do you think happens to the rumble's tone coloring? Oh, and is the delta comp still in play when you do this?
i just ran this last night, put my SWR Grand Prix into the Return jack of my 500c along with the 115 extension cab and it sounded really, really good! Got quite a few compliments on my tone and had plenty of power for the 125 capacity venue.
