Wah

[FLHX]

Is a wah suposed to be run through the fx loop? When I run my dunlop through the loop, the lows are cut off. The highs are fine.

I run mine before the amp, usually before any OD or dirt boxes. Maybe a tuner and compressor before it. I've never run one in the effects loop. I use the loop for time based effects.
YMMV, so experiment.

Run the wah in front of the amp. Always.

My wah is always first in the chain after my guitar. I then go through my other pedals then into the guitar input on the amp.
