I plug a condenser mic into my pa system them started playing close to he mic but it was that loud, and if i turn it up any louder i start getting feedback! How do people play through a mic, like is it setup properly? Maybe its my dudgey mixer
Typically Condenser mics are used for recording, not 'live'(through a PA).

Usually Dynamic mics are used...
Washburn D-12
Ibanez RG
Ibanez RG 7321
Epiphone Les Paul / EMG 81 85
Fender MIM Ash Stratocaster
Digitech Whammy
Small Stone Phaser
Boss SD-1-Modded
Boss MT-2-Modded
Boss CE-5
Boss DD-3-Modded
ISP Decimator
B-52 AT-212
Condenser mics are very easy to overpower.

Like Reil said, get a good dynamic mic.
