I have tried them all and would highly recommend the Line 6 HX Effect. It’s just effects, no amps, which is what I like. You can find them for $500 or so new. These things have everything you need and don’t take up much room. You can set up a ton of 6 button pedal boards you can pull up anytime. If you want to go with a very high end unit, I have a Fractal FX8 that is like new I would sell for $625. However I still say look at the HX Effects.I'm recently interested in getting a cheap (but good) multi-effects pedal, I've had Digitech before and want to try something different, I found the Zoom G1X Four, its got good reviews. I want to use it to switch between rhythm and lead tones on one button and turn effects on and off with the other button, and use the tuner too. Does anybody have experience with this model, its priced right and has lots of effects and features, I might just order it and demo it for awhile to see if its a keeper. I want to use it with my newly built 5E3 and add the Zoom as a part of this new grab and go rig.
