Yes the GK3B dialed in with the upright bass setting sounds real good, it's one of my favs,too! The fretless aint bad either. You can get lost for hours playing with the VB-99, has some wicked synth effects for your bass too! But too unlock the full potential the GK3B pickup is needed.Sometimes I run it thru my Andromeda A6 and trigger it with midi. You can do that with a wind instrument as well. Great sound Jino
