If OP was looking for a small copper hybrid mod, XXiX is better than 4nine, IMO, as it is a single tube. But I have previously been refraining from commenting on this thread since, when looking at fasttech clones, they are all so cheap anyway and its good to have backups, so why not just get a couple of mods that interest you? Or just get the 4nine and if its not what you expected, no biggie.
