I've been thinking about getting and modding an Epiphone goth thunderbird IV. There are two main mods: A Kahler trem and pickup swap but I have a couple questions and doubts. First of all about the bass itself. How well made are these instruments? I get they are cheap but are they actually decent basses? Also the higher fret access is pretty important for me. Then the mods. Will a Kahler even fit on a thunderbird and do I need the rearward or forward saddles? Now this may sound kind of weird but I want some more balanced pickups, something that will let me play a variety of genres. I don't mind if they need routing as I'll probably hand the bass off to a luthier anyway. Finally, will it even be worth it? It's a cheap bass and these mods might actually be equal to the cost of the bass. I play a variety of music so I would want it to be versatile with the new pickups. Honestly I just want it to be well balanced and sound good and a decent bass for the price with a trem of course.
