Atomic Amplifire External Drive Pedals, Before the input or in the loop

[synthetica]

As the title says, where better to place Was, Drive Pedals, Before the input or in the loop and why ?

Now that the loop is moveable you can put them in either place. Putting them in front saves your loop for time based effects you might want in the loop or allows you to use the loop for expression pedals. Using the drive in the loop allows you to switch it in and out per preset if you want.
