I recently picked up an used Eko MM-305 5-string Stingray copy for a fairly good price. I love the playability of the bass as it has a tighter string spacing and the neck is not too wide (I'm a small guy with small hands!). I can also get the action much lower than on my Music Man SUB USA, which is great. The bass sounds good now, but I'm wondering if I could make it more growly and 'Stingray-like' by switching the pups and possibly electronics? Do you have any recommendations? Also, could my bass be changed from passive to active? I know, I know, my Eko will always be a cheap bass and it'll never be a genuine Stingray, but as a student I really can't afford a real EBMM bass. I'm also not asking if it's worth it because I won't be selling the bass and I want to explore the world of modifying instruments as there's something rather cool about having an instrument that you've actually improved yourself. What matters the most to me is that I have a bass that I like playing.
