I am thinking of ordering a Barber Dual Discrete. I already own a bunch of his pedals at the moment, and should be able to answer my own question with some testing, but I was curious which combinations people like and why. Which two Barber pedals would stack best in one enclosure, which order, and why? I have an LTD SR, Gain Changer, DD/DC, and 1/2 Gainer. I am thinking LTD > DD or DDLG.
