Introduced at NAMM, the Peavey Headliner ($459.99 MSRP) is a new rackmountable bass amplifier head for the Peavey Tour Series.

Bassists will like that the Headliner outputs a whopping 600W. Additionally, the head features a seven-band graphic EQ spaced at optimized frequencies with each slider providing 15 dB of cut and boost, to provide comprehensive tone shaping at precise frequency bands. You can use the graphic EQ in conjunction with the low- and high-shelving-type tone controls, or bypass the graphic EQ entirely.

A built-in optical Compressor with level control and bypass allows you to add the desired amount of compression to the mix, while the Crunch feature adds a vintage tube effect that distorts only the high frequencies. The amp also sports Bright and Contour switches, effects loop, master volume, and headphone out. The Compressor and Crunch features are footswitch selectable.

The Headliner features a built-in XLR direct interface that can route the signal to the house sound system or recording device. In addition, an active / passive pickup switch compensates for hot inputs, and DDT speaker protection circuitry senses the onset of clipping and responds with slight compression that allows the amp to retain the tone, headroom, and dynamics. The bypass switch comes included.

Peavey will begin shipping the Headliner bass amplifier in the second quarter of 2010.
