So after a few weeks of pain i have finally gone for to the bass community for help. Let me start out by saying i am new to the bass and thus dont know much so your patience would be appreciated. A few months back myself and friends got together started jamming and played a gig. Not having much money I bought what i could afford. I purchased GK Backline 600. Its got 300 W @ 4 Ohms. To go along with this i bought a GK Backline 4 X 10 Cab. This however has 8 ohms. The bass i play is a Spector. The problem i have is that everything together sounds like straight up garbage and the more i toy with it the worse i think it gets. Without the pad switch on it is Way louder but the tone suffers greatly. With it on ...the volume is cut in half and have to crank the boost up to cut over the drums. It also begins to sound distorted when the master volume is at half way. If the Volume is low or if is hit the strings gently it actually doesnt sound bad. But i play in a hard rock/retro metal band so when pluck harder the sound gets farty and an unbelievably annoying clicking noise happens.(the clicking i believe to be my basses fault) So any help on either how to fix this problem or what new amps and bass to buy would be great. I've also plugged in passive basses and this does sound better but still not great.
