Ok I have a Gallien Krueger 800 RB amp it is biampable (300 to lows, 100 to highs) i am running it to a Bag End 4x10 and a tweeter via the low input. I want to bi-amp but i dont know whether to run to bad end to lows and get a 2x10 or 2x8 and a tweeter for highs or get a 15 or 18 for lows and the 4x10 for highs. Which will give me the more bang for my buck. the bag end can handle 800 watt and I am looking for a good slap tone. i like having a low growl but still want to be able to hear when i pop the G string which unfortunetly i can only have one or the other now. What should I do?
