ok, i just got a marshall jcm 2000 dsl head and i have used it own a 15 cabient and it is to bassy yet it is crisp and has alot of presence. SO i tried hooking my marshall to a solid state amp so that i would just use the speaker(s) from the solid state, and when i do, it isnt bassy, but now i kinda seems like it has alot of mid range and also its presence is little so it sounds muffled. I dont know what im gonna do because i got to play at a party not to long from now. Please help me on maybe something im doing wrong if anything.
