First at all Thank you so much for all whom reply so fast to me!
i will take your advice , some of suggestions are out of my budge but maybe can be my next step to make when i get a bigger budget for this
something i forget to mention is in my country most of the venues are very tiny (around 20 or 100 people full capacity), and mostly music im into it is noisy music like heavy metal (death metal, black metal, etc) which is something to know and i forgot to mention, also i live in central america not many people are into tapping live music so no many gear in second hand are available around
thanks again to people who share knowledge with me
