Hey guys i am new to the forum. I am having a loud pop when switching loops and loop number 4 is robbing all tone from the pedal in the loop. My setup is as follows Loop 1 Boss compression/sustainer Loop 2 boos dd6 digital delay Loop 3 deltalab stereo chorus Loop 4 Sans amp us steel. This is the first time having this problem i have brand new wires so i know there is no problem there and i am powering the swticher with a furman spb-8 board (using the voodoo lab adapter of course). Any tips or advice?

How are you powering the four pedals?

Try pulling all but one of the pedals to see if the problem is related to any particular pedal... if not, keep adding pedals until the problem comes back.
