Stupid question, I know. My local GC has a used ATK (older model, bridge pickup only) and it is literally the best sounding bass I have EVER heard in my life. It's like mid range punch with fullness and a voice like I've never heard before.. I'm not wanting to buy a new bass though. I have an SR506ZW that I treat like a child that I don't hate. The tone is good, but it's very... modern, if you will. It's sonic flexibility is fantastic, but I don't really feel like it has its OWN voice like the ATK does. Would different pickups give it more growl? I've heard good things about Nordstrands in the SR Premiums.. I assume I should ride the bridge pickup more.. Any suggestions?
