This is what Spector say:
“The Spector TonePump® Active Bass and Treble control is provided by means of 2 continuously variable controls. There are no center detents on these controls. In that way, you are in control rather than having “normal tone” dictated to you. Slightly rolling in a touch on both the Treble and the Bass control will provide a flat frequency response. Continuing clockwise, the Spector TonePump® will provide 18 dB boost in both the Bass and Treble range. We have “A/B’d” the TonePump® against all of the major bass “pre’s” in the market and have found that it offers greater headroom, gain, and control that anything out there. The Spector TonePump® is a 9 vDC circuit and is our most aggressive preamp to date”
This was bought new in 2012 and barely used – it’s like new. A great choice for gigging as it’s light, has simple but ultra efective controls and a superb fast playing neck. It really is good!
