Highlights

  • Sculpt Your Tone

    Featuring two Pre-Amp input knobs, allowing custom blending of tube and solid state tone, and ten-band graphic EQ, the 3500 is ideal for the player who wants plenty of power and control. But we don't stop there. A dedicated preset button allows you to set a equalization curve and two fully adjustable contour knobs provide even more shaping of your distinctive sound. A built-in compressor adds real "punch" to your bass sound, and also allows you to smooth out volume differences between notes. Rugged construction and professional features make the 3500 totally road-worthy. Two independent inputs accommodate both passive and active bass guitars. LEDs that show you the settings of the graphic equalizer in low-light environments as well as a two-color LED that continuously shows the status of the compression circuitry in response to your playing. Electronically balanced direct output provides routing signal to professional mixing consoles for both live performance and recording environments. A ground lift switch helps prevent hum or buzz from entering the signal, and a pre/post switch allows the direct signal to be derived either before or after the amp EQ section. With all the features you need for complete tonal control, along with ample power and rugged design, the 3500 will ensure complete bass euphoria no matter what kind of music you play.
