I'm looking for some specific features that a few pedals all seem to have but I'm hoping for some user input here. I currently own an Akai Headrush 2 and while it's great for simple overdubs on the fly in a live setting, once you start to get past the 3rd overdub the sound quality is essentially unusable and too muddy. Furthermore, the loops get so loud that normal playing is lost in the mix. I've tried all sorts of tricks like lowering guitar volume, etc but in the end if I have 6 or 7 overdubs the track becomes essentially a blurry mess. Additionally, if I wanted to remove the last 3 or 4 dubs I cannot do that. That search led me to looking into a multi-track looper.. something where I can use one loop for the constant beat I'm looking for but has another loop that allows me to layer my sounds together and then be able to remove that loop and get back to the root rhythm I was going for. It would also be great if I could route one loop to the input of one amp and another to the input of a different one. This is not a requirement but it would help out a lot with the looping getting too muddy I would imagine. I've been looking at the Boss RC-50 and the EHX 2880. Both are around the same price (expensive ). The sound quality needs to be high because after numerous overdubs the quality is just unbearable. I've also read about the Boomerang but it doesn't seem to have as many features. So can anyone assist in my search? I'm fine with the pricetag as long as it does exactly what I need it to. One last question, if the looper has multiple outs, can I just run a cable from the 'left out' to the input of one amp and the 'right out' to the input of another amp like it seems you can?
