I just bought a Spector Euro LX5. Thought it had the DC's but came to me with the TW's. Apparently Spector is using these now instead of the DC's on the Euros and some other models. I find the sound of the TW darker in color without the zing of the old DC. Dont care for the slap sound it gets either. The single coil mode on this bass is only a reduction in output not tone and is only useful if you want to play at a lower volume being the tone pump tends to be loud. How do you feel about them? Jury is still out for me on these pick ups. 
Of note, Spector has discontinued the DC line on the Euro's.
