This little test was born from trying to figure out how much the buffers influence the clean signal. An attempt to 'see' the effects on the wave going through different buffered pedals. The ones I have used in this test is an old Rocktek, a Behringer, BOSS and a Zoom digital multi-effects unit.

The new trend to want true bypass guitar effects pedals is well known and the reasons are sound (see what I did there? sound...). As a guitar player you want to eliminate anything that will alter or ruin the truest sound you can get. So the obvious go-to's are pedals that are true bypass.
