I got a gibson sg recently i love the sound and feel but i have problems with feedback and it sounds bad through my little amp but great through a good tube-but a good tube is beyond my grasp financially

so i could get new emg pickups, new gibson pickups like the ones on a standard les paul

or i could wait and get the new amp in a while-i may need the new amp to since im now in a band and oplanning to play live
