I am currently using a Fender Rumble 100 amplifier with a Epiphone Thunderbird Pro IV. I am almost always unhappy with the tone I get from this setup, and am pretty green at terminology and don't know what to do to fix it. Is it something I can change with the gear I have already? Or should I upgrade my bass? My amp? Let me know and feel free to ask me questions and be thorough.
