Okay so I have a few questions about loopers/line selectors. As of right now I'm really loving the distorted sound of my Tronographic Rusty Box going into my Darkglass B3K, but for what ever reason, at the moment, I prefer the clean tone of my Tech 21 BDDI over the Rusty's cleans. Now the BDDI does not, in my opinion, sound too good when combined with the B3K so I can't just use the BDDI with the B3K, when I want more dirt, I need to have the Rusty and B3K together...but I can't have the BDDI engaged when these two pedals (the Rusty and B3K) are on. So simply put, I want to be able to switch between the BDDI for my cleans and the B3K and Rusty Box for my distortion. Would a pedal like the Boss LS-2 solve my problems? I took a look at the manual and I think it would but I'm not 100% sure. Also, if the LS-2 would solve my problems, how would I hook it up? And finally, roughly speaking, what are the differences between the Boss LS-2 and other more expensive or less expensive options?...cause it seem to me that with such a simple effect there would be little to no difference. Hope that all makes sense and thanks in advance.
