Playing live with Band and Volume

I play electric guitar and I play harp solos while I play with band. I use my vocal mic and I seem lose the harp in the mix unless I cup the mic, which isn’t practical as a guitarist. Naturally, Not being able to hear makes soloing difficult.
Has anyone ran into this and what solution did you use?

It’s the nature of the beast. There are gadgets that cover the harp and mic but I’ve never seen a hands free one. You may as many have done have to choose whether you want to play harp or guitar. If you want to play guitar get a good harp player if you want to play harp get a good guitarist.
