A few years ago, I customized my old Fender Jazz with the 24-fret extension neck from Warmoth. It played well, I enjoyed the two-octave range of each string, although it was kind of a pain to reach frets 22-24. These days, I am playing an American Tobias Growler 4 - string. I love everything about it, but I want to expand my arsenal. The only options I have in the category of American - made 24-fret basses are exorbitantly priced. I have heard only excellent things about the Gecko 5 and 6 strings (price, playability, design), plus I would love to put a bass together myself. I would really like arty07: to see a G4 bass built to accomodate it's own 24-fret neck (not the Fender extension neck).
