Hi all. I recently purchased a Musicom Lab 8-way Looper, which says it has a high quality input buffer. When I plugged one of my favourite (and expensive) fuzz pedals into one of the loops it sounded really wrong - something was just not right with it. So I looked in the manual and it said that if you have a fuzz pedal with a Hi-Z output connected to any of the first 4 loops then you should turn the buffer off. So I did this and now the fuzz sounds normal again. So I guess I just keep the buffer off. I know very little about buffers and impedance but this experience has left me wondering whether any future loopers that I may purchase are better to be buffered or not buffered. Has anyone else any experience or knowledge to share about this? Cheers.
