I'm thinking about getting an amp that has a passive effects loop, but I'm not too familiar with the different types of effects loop (active/passive or buffered/non-buffered). I tried doing some research on it and I kept seeing something about tone loss with ones that are passive (non-buffered?). I know what the purpose of the loop is I just to make sure it will work like I want it to. The amp is a Two Rock Gain Master 22 and the delay will be an El Cap or a Timeline. Does it make a difference if I use the buffer on the delay? Should I expect any issues? Not sure if this should go here or in the amp forum, but I figured I would try here since I'm sure someone uses delay with a passive loop.
