Can you use a wah and then have another pedal for another thing? Does this even make sense ? Do guitarist even use 2 pedals ever? I am so new to this so just asking about some thoughts I have
As many as you want.
what amp you using?
generally the conventional way to chain up pedals is; first in chain wah type pedals, then overdrive/distortion, next would be modulation type (or put these in an effects loop), lastly adding reverb and delay.
BUT there is no hard and fast rules, try different things if you like the sound that's the main thing.
