I recently have been rehearsing with a hard rock cover band where we are trying to put on a high energy show. There are enough songs that will need effects that I'm considering purchasing a multi-effects processor so I can have enough presets to easily and quickly scroll through between songs. Whether you use multiple pedals or multi-effects, what are your favourite, must have, always on pedals/effects in your chain regardless being clean or distorted or other effect on top? Feel free to add why or how you use the effects. Thanks in advance!
