Barber Electronics is proud to introduce a powerful update to our now legendary Tone Pump!. The Tone Pump has a new tone control design that allows for an even clearer and more dynamic sound. The "EQ" update adds controls for presence and midrange... With the well thought out new "EQ", you can sculpt a vast "tonescape", from flat mids to extra articulated silky highs and a new deeper clearer bass and all points between. The "pump" control for the red channel is now push/pull to go between asymmetric and symmetrical clipping. All this adds up to an exciting new Tone Pump that veteran and new users alike will love!
