ENGLISH The new sound of metal is here. The Invective™ 120 is the culmination of nearly three decades of refinements and tweaks to Peavey’s legendary 6505 series with an all new clean channel and gobs of peripheral features that are staples for today’s developing musical styles. Designed in close conjunction with Misha Mansoor, of Periphery fame, the result is a monster of an amplifier capable of accurately reproducing tons and tons of the sickest tube amp tones imaginable….past, present, and future.

(6) POST GAIN This control, on the CRUNCH and LEAD channels, sets the overall level of its respective channel. (7) LOW, MID, and HIGH EQ These passive controls, on both the Crunch and Lead channels, provide the signature tone print of the Invective 120. (8) PRE GAIN This control, on both the Crunch and Lead channels, controls the input volume level/gain of its respective channel. This control will increase the amount of preamp distortion and sustain.

(23) MSDI SECTION The proprietary Peavey MSDI circuit provides a balanced microphone-simulated direct signal to outboard recording gear and mixers. The “microphone” compensation very accurately reproduces the sound of whatever cab you are using in conjunction with the Invective 120.
TOP PANEL V5 V2 V1 29 V9 V10 V8 V7 V6 V4 V3 30 12AX7A/ECC83 x 6 Preamp tubes. Tubes function as follows: V1 = Crunch/Lead stages 1/2 V2 = Crunch/Lead stages 3/4 V3 = Loop driver/PI driver V4 = Phase Inverter V5 = Crunch/Lead stages 5/6 V6 = Clean channel 6L6GC x 4 Power tubes. Apart from 6L6GC, other types can be used including EL34, 6550, KT66, KT88 and 6CA7. When replacing please use matched quartets of good quality tubes and ensure the biasing is set correctly as described below.
FOOTSWITCH 32 33 34 35 36 37 38 39 40 41 31 (31) Remote Cable An eight-pin DIN connector is provided for connecting the footcontroller to the amplifier IN/FOOT (38) via the cable included in the carton. (32) Preset Mode Switches the footcontroller between NORMAL mode (default, LED off) and PRESET mode (LED red). Other LEDs will be red for Preset Mode, and green for Normal Mode. (See “Using Preset Mode” section on pg. 10) (33) Effects Loop 1 / Preset # 1 NORMAL mode: This turns on Effects Loop 1.
(37) Drive Boost / Preset #5 NORMAL mode: This turns Drive BOOST on and off for the current channel. When switching between channels, this will remember what the last setting was for each. The LED will be green when Drive BOOST is on. PRESET mode: This selects Preset 5. If selected, the LED will be red. (38) Channel Select 1 / Preset #6 NORMAL mode: This selects Channel 1. The LED will be lit GREEN. If pressed a 2nd time, the channel will return to the previous setting.
You can initiate this from PRESET mode or from NORMAL mode. After the store (or cancel) it will return to the mode you were in. So you can setup and store 9 presets without ever entering PRESET mode if you wish. It’s typical to set up your sound in NORMAL mode, then store your creation to one of the presets. QUICK BOOST As described below, when in preset mode, the 1-9 switches will recall your 9 custom presets.
MIDI IMPLEMENTATION This amp is designed to be extremely functional with the included 10-button footswitch. The 8-pin footswitch jack also works as a standard 5-pin MIDI input - to go along with the standard 5-pin MIDI output. There are times when the amp will be run with other types of MIDI foot controllers, a PC in the studio, or by an automated rack rig - or linked to another Invective via MIDI. This is the information you need to mate this amp with other MIDI devices.
MIDI PROGRAM MIDI Program Changes are used to recall presets. Typically a preset will reconfigure all functions on the amp at one time. (Programs 9-11 below are exceptions as they only affect the channel.) NOTE: These messages when recevied will be echoed to the MIDI Out jack for sync’ing with another Invective. NOTE: The first nine presets are your custom presets. They recall whatever you store with the footswitch.

MIDI SYSEX MIDI System Exclusive Commands are used to do all kinds of things that standard commands don’t handle. The Invective uses Sysex for things like backing up or restoring the 9 user presets, or transferring them to a 2nd amp. NOTE: Except where noted below these messages when received will NOT be echoed to the MIDI Out jack. BUT if the message does not have the matching MIDI channel of the first amp, it WILL echo it in case the 2nd amp matches.
