Hello, Not much experience here with different kinds of gear over the years, been mostly a "plug and play" guy. I have a Fishman Pro Platinum pre amp, which I like. I go through the effects return channel on the back of my SWR WorkingPro 12. Do people ever use these through the regular input channels? What would be the advantages or disadvantages of doing so, and if I did where would I set the tone controls on the amp? Also, when going through the effects return channel, where should I set the EFX blend control, dry or wet? Thanks for any info!!
