I have this one with the graphic eq and its the most versatile bass I own. The T40 comes in 2nd for variety of sounds. I dont own a Line 6 but thats digital modeling so doesnt count. I love the kitsch body shape. Also the bridge pickup is great and very usable as I dont like bridge pickups in general on solid bodies. Used it with Glen Matlock and on many tracks. Does dub to nasty and Ive had Entwistle esque sounds. The eq knobs are paired to boost and cut 2 frequencies simultaneously to keep volume stable but if you take of the knobs you have a 6 band eq but the volume can vary immensely. LOVE IT!!
