Agreed with the LS-2.Neither will work. The Killswitch is a single loop box (select either straight through or through the effects in the loop) but with a momentary switch, while the Switchblade is an A/B (one input to either of two outputs). You need something with two loops - loop 1 for all your clean fx, and loop 2 for the pedals used for the lead sound - and the ability to switch from loop 1 to loop 2. Check out the Boss LS-2 - it's one of the most useful tools out there![]()
