i tried one in a shop in notts - sorry matey, but it was awesome! sounds unbelieveable for the price, i like the look, but having never played another thunderbird, i dont know if the neck dive was massive or not!
compared to more normal shaped basses the neck dive is what stopped me from buying it, i know there are mods you can do, but i cant see that bringing it to a point where it would be useable for me!
quite a wide nut width for 5 strings i usually play, but very comfortable none the less, tension on the b aint great, but dealable, and i have to agree its a fast neck!
i believe you can pick them up for about £350 - absolute fookin bargain, if you can deal with the shape!
apologies to the OP - hows your gas? lol
