I bought a Lehle D.Loop today and couldn't wait to get home and use it, I'd been using a buddy's Morley. Well first off it wasn't as quiet as I thought but the biggest thing [unless user error here] is it won't send to both A and B loops at the same time. I have the guitar to input, A send to amp A, and B send to amp B. With A on, A amp outputs. With B on, B amp outputs. With A and B on, just A outputs. Another odd thing, the manual says press set and all the lights will come on to enter programming, they don't. So I held reset down for 3+ seconds and everything still acts the same. I don't think I'm doing something wrong here but it's definitely possible. I tried the regular output to amp B but it defeats when either A or B are active.
