So, I just recently purchased a Fender Rumble 500 v3 from Sweetwater to use as my bass amp in my band. I wanted to bypass the preamp by the return of my effects loop to run my Sansamp Bass Driver a as the di. I read in the manual that the effects loop is post the preamp section of the amp. Is there any point to running into the return in this case? Thanks for any constructive help.
