I originally wanted to get a Boss LS-2 but it unfortunately cannot have its two loops in series, only parallel routing is possible. This Electro-harmonix Switchblade Pro can do both with the series/parallel switch. This also has the additional dry level knob that the LS-2 doesn't.
My Switchblade Pro is on a board that I use with both guitar and bass. I have it set up with my drive and distortion pedals in loop A and my modulation (chorus, flanger, phaser ect) pedals in loop B. Here are some of the ways I use this
- Use the dry level knob to blend in the dry signal when I'm using my distortion/fuzz pedals on bass to retain the low-end on distorted bass tones.
- Use the A/B footswitch with the A+B footswitch off to instantly switch between two sounds : a distorted sound and a "clean" sound with modulation.
- Use the A/B footswitch in series mode to easily change the order of effects. This way, I can have my modulation effects either before or after distortion.
These are just some of the ways you could use this pedal. There's so much more you can do with it. If you don't have the space or the money for large switchers like the Boss ES-8, something like this can simplify turning multiple effects on or off at the same time and opens up new sound possibilities.
