The Dual Loop Box allows you to control two separate effects loops within your system without the mess or complication of having two entirely different loops in your pedal board. Control two separate effects loops, in series. Runs two independent or series effect loops. Takes signal degrading pedals out of the signal path. Change the order of the two loop,Here we have a dual true bypass looper pedal which gives you the opportunity to reverse the two loops. If you have a distortion pedal going into a flange pedal you may also like the way they sound with the flange going into the distortion. With this pedal you can have both options on the fly, without having to get on your knees to change cables mid song!Both loops are individually activated by the front switches and you can reverse them using the rear switch.
