The Radial Engineering Big Shot EFX is an effects loop, designed for making your clean signals as clean as possible and to minimize signal loss in your chain. The pedal has two switches - one for each of the two channels, as it has 1/4" inputs and outputs for two separate channels. In essence you're getting two effects loops in one here because of this, giving it a leg up right off the bat. It of course also has 1/4" connections for your instrument input and amplifier output, and isn't rack mountable as it is a foot pedal.

Setting up and using the Radial Engineering Big Shot EFX couldn't really be any easier than it is, as there isn't much to know here at all. Simply make your connections - running your pedals through the loop and your guitar and amp straight through the pedal, and you're good to go. A manual definitely isn't needed to use this in any circumstance.

While the Radial Engineering Big Shot EFX doesn't make any sounds, rather it adds by taking away. With your instrument plugged through the Big Shot EFX, you can have effects plugged through only when you need them, eliminating any hum you might have gotten from them and making sure that you're not losing any signal quality at all. This is a worth while box to have for any player using effects...

While a bit more expensive than most looping boxes, the Radial Engineering Big Shot EFX is probably the best of any that I've used. It is built extremely well and the fact that it has two channels is a huge plus. The price isn't too much more expensive, but it is a noticeable increase in price when compared to other loopers. Even so, I'd say it is worth it for the extra channel and the super clean sound quality you get with it overall...
