i have a boss dd-20 and boss eq-20. which should go to fx send/return and which should go to input along with guitar?
just pu both through the input
Actually, the DD20 should go through the effects loop so that the effect doesn't become distorted if you use the amp's own overdrive. I'm not sure about the EQ, though. I guess it could go through either, really.
EQs can go before or after OD/Distortion for different sounds, see what you like best. Most put it in the loop though.
