With the Peavey Invective 120 you get an all-valve, premium-grade guitar amplifier head that's specially designed to deliver tones ranging from pristine cleans and no-compromise high-gain performance and everything in between.

3-Channel, 120 Watt Valve Amp

This awesome amp has been designed in conjunction with both Peavey and modern-day guitar legend Misha Mansoor, and delivers a powerful, all-valve driven 120 Watts of output backed up tone-shaping features galore.

Peavey Invective 120 Guitar Amp Head Key Features

  • Powerful 120 Watt amp head, designed in collaboration with Periphery's Misha Mansoor
  • Three channel design - Clean, Crunch, and Lead
  • Two 9v DC Auxiliary pedal power outputs
  • Specially-designed output transformer results in a tight, powerful bottom-end and soaring top-end response
  • Includes a 9 preset footswitch

Premium Construction

A valve amplifier is only as good as its internal components, and on that front the Peavey Invective 120 certainly delivers in style.

Featuring four matched JJ6L6GC output valves with top-loaded bias test points and adjustment, and much more besides, this amplifier guarantees a reliable performance every time you play.

Pedal Power

A unique feature for the Invective 120 is the inclusion of two 9v, 500mA output sockets to power even the most current-hungry of pedals in the effects loop.

Whether you wish to daisy-chain your entire pedalboard to these two outputs, or preserve them for specific pedals, the choice is yours!
