Daft FX loop level question

Bidley

Just a quick one (I hope); what is the accepted wisdom for FX loop level settings? Mine has a switch for 0db, +4 and -10. I've had it on 0db forever but I'm wondering if it should be on -10, as I'm using pedals in it. I remember reading somewhere one setting or another is better suited for racks but I can't find an article for the life of me!

Use the highest level which doesn't make whatever you have in the loop distort, since that will give the best signal-to-noise ratio. If you're not getting distortion on 0dB there's no reason to use -10. +4dB is the one that's suitable for rack units and is above the level most pedals will take though.

I've found the best results using +4dB (which, funnily enough, is all my Jet City amps can do) with TC TonePrint pedals. Actually, that's kind of backwards...I use TonePrint pedals because they're the only ones I can find which can reliably handle my amps' loops

Nice one, cheers for that! One more thing, I assume 0db is line-level?

No - +4dB is line level, -10dB is instrument level. 0dB, rather predictably, is somewhere in between

Top info, cheers dude!
