I just got a Laney VC30 and see it has an effects loop. Have had amps with effects loops before but I always just do it the old fashioned way....guitar into pedals, lead out of the pedals to the amp input. I don't have a bank of pedals, only a Vox multi effects unit. I see my amp has an effects level knob too, must be to control the level effects have on finished sound. What are the benefits of using the effects loop as opposed to putting your effects straight into the main inputs of the amp?
