I own a lovely Thumb5 neck-through and fel that it is now time to replace that shoddy MEC junk. I have had such bad luck with their crap in the past...microphonic PU's, preamps cutting out in the middle of a live set (on TWO different Warwicks!) I am thinking that it is possible that the new 18v preamp in this Thumb may be ok but who knows...? I would definitely like to replace the Jazz PU's and am open to suggestion. Bubinga is a fairly dark and deep sounding wood so I am thinking that Barts wouldn't be the best choice. I do like a fairly aggressive tone....SD's? Dimarzios? Suggestions....?
