OK so a quick google search and I'm looking at a range of mini/portable Amphs/PAs....

The Roland Cube Street looks ideal, then I saw the Soundart 450R - which makes specific reference to having an Fx loop which to date I've found quite important...
The CubeStreet does not seem to have this so general question is having the Fx loop on one of these things important? It seems so with normal guitar amps (distortion generated by drums aside for a moment) as I had issues with 'clipping' when using the ME-50 + open backed amphs. Guitar would go into ME-50 THEN into amp and once volume was turned up a little would cause all sorts of nasty's.....

Now the guitar goes straight into amph, out the Fx channel to the Tuner, ME-50 and looper and back to the amph again.....

So.....again LOL is it important to have Fx loop on these PAs?
