Hi im looking for a new bass 4 string bass. I have a 4 st fretless warwick corvette. And a Corvette $$ 5 st. I think im looking for a growly thumb, but i find the warwick less singing than the Spector. I find my Warwick middle, trebbles a little harsh to my ears, dont know how it would be the Thumb. Here is a little difficult to play both basses, specially the spector. Do you have any sound clips, to compare? I really like Ryan Martinie Thumb tone, but dont know if i would like the bass in another context. How growlier can get the Thumb and the Euro? I dont know how to tell, it seems as if the Euro has more of that candy sound (on steroids) found in the jazz bass with the tone on full. That the W, doesnt have. This is the growly tone i say: Is this tone exclusive or if it can be eq'ed with more flooring move bass (like jazz bass). This is a Spector: The Spector sounds more bassy, round. the Thumb sounds like it has some anger inside. Same Mudvayne disc LD 50. Thanks.
