The Tube EQ is one of the pedals in EH's 2004 lineup, though it's not intended to function as your standard equalizer, instead enhancing your tone and giving you more options than a regular EQ.
Inside the Tube EQ are two filter sections. The first provides passive high and low shelving functions, which correspond to the Bass and Treble knobs on the pedal. The second section is an active parametric bandpass filter with frequency, Q, and gain, controls. The pedal has your standard input and output jacks, but also offers an insert for using an expression pedal. When in place, the expression pedal will sweep the center frequency of the bandpass filter, allowing for 'wah' effects.
The Tube EQ carries a 1 year warranty.
