I have spent enough time with the DD/DC to give decent review. The V2 Direct Drive (green led with the push/pull tone knob & no trim pots) has been my favorite OD pedal for years. I do not love all Barber overdrive pedals for various reasons, but I've held on to my V2 DD for about 6 years now. The DD/DC is really amazing. It's transparent on both channels. It does what it's supposed to. Low gain DD & regular. The mid knob could be what puts it over the top. The best thing about this pedal is the same thing with the 1/2 Gainer, you're not stacking 2 pedals on top of each other for leads or needed volume. Like most Barber pedals there's a ton of extra volume on tap if needed. Unity volume with your amp runs at about 12 to 1 o'clock. For me this pedal picks up where the 1/2 Gainer left off. I could never bond with that pedal like I expected. This is the pedal I've been waiting for. Glad I pulled the trigger..!
