Eq's setting are always personal I know, but I suggest you to lower them a bit (maybe try to keep the same proportion, just say like T:7, M:5, B:7).
With your eq at its max you won't be able to raise anything if you'll need to; if you keep them down a bit and you'll need more bass or more mids you will able to raise them.

How high are your pickups?
With single coils the tendency is always to have them higher than they should be; this will give you more impact on the sound, but will kill your dynamics and especially your sustain because of the magnetic field of the pickups that will not let strings free to vibrate.
You may need to lower your pickups too.
Oh, and what about your strings?!
Are they too old?! New strings sound better than old, dark & beaten strings!

If the gain of your amp is at 10, when you add volume you won't be able to control anything that comes out of your guitar. Remember that ultra high gain works fine at home, at low volumes, but if you play at high volumes it will make your sound uncontrollable and noisy.
So -again

- lower your gain will help; try to keep your guitar's volume at 8/9 and find the right setting of your gain so if you'll need more volume for a solo, you can raise your volume at 10 (or you can buy a booster). Doing this you will totally control any sound of your guitar and prevent unwanted feedback.

I think this are the general consequences of all the previous stuff i.e. eq, gain, pickup height...
You maybe use your mid pickup because it's not so powerful than neck or bridge ones and can help you in not getting that feedback, but it can sound so flat...
Remember that with a sound that fits your need (which you have slowly create manipulating all the previous matters) you'll be more free to express yourself in a kinda stream of consciousness when you play, because you won't need to concern about what is coming out your amp or any noises or whatever... You'll be sure that sound speaking everything will be ok and you'll
only gotta plug and play
