So since i got my wah pedal i've been playing standing up however my neck after like 10mins is SORE as fsk.

What am i doing wrong?

I have my guitar slightly high up,

But the back of my neck just feels really... tense
If possible, take a picture of how you stand and wear your strap. It'd be much easier to tell you what you're doing wrong

Do you bend your head forward alot too look at your guitar and wah? That might be the problem, try to have good support from your back and look forward with a straight neck.
