I sent the twin on to its next trial bassist. I love that sound of the two and maybe I'll buy one but right now I have a micro pedal with a tuner looper HPF and redeye and it is all nicely hooked together and daisychained and I just plug and play and it sounds so good and is so nice I dont want to mess with it. But the 2 Yama's into the twin sound great.
You really don't miss having any EQ in your signal path (besides HPF)? I'm skeptical on that point, but very intrigued by this thread. I'll have to pick up a Red Eye soon.
