I've tried a Snouse BlackBox, J Rockett Blue Note Tour Series, DOD Looking Glass, and a Barber Gain Changer, and to my ears, the Morning Glory is the most transparent. It just adds a little sweetness to your tone. The eq sounds very flat to my ears. I would not recommend a MG to anyone who would like to use it for lead work, unless you run a lot of mids on your amp eq. There is no mid hump that I can hear. Snouse BlackBox: Sounded nice but added something to the highs that I didn't care for, and turning the pedal on produced a strange ping noise that was annoying. J Rockett Blue Note: Great sounding OD but when comparing it to the Gain Changer, I felt the GC sounded just as good at a lower price. DOD Looking Glass: I love the breakup of this pedal, but felt it sucked too much mid range and the highs were a little overbearing. Gain Changer: Great pedal at all gain settings. I've moved it to a mid/high gain position on my board for now.
