I am a mobile DJ here serving Northeast PA. I have been DJing for the past 4 years (the last 2 years have really exploded and grown!). I learned much of what I know from my dad who has been DJing for 25+ years. All of my equipment is MINE, I have bought it all from money from past gigs (90% of what I made when back into equipment). I would be glad to help anyone who is getting into (or thinks they might want to get into) the DJ business I have a decent amount of knowledge and let me know if I can assist you!....If I can't answer your question make sure you ask Brain S. Redd or Johnathan (DJ Tutor). They have been in this much longer than I and are always a GREAT help!
