Small, yet mighty - this compact all-tube preamp and power amp authentically reproduce the much-loved tones of its larger counterpart, the Invective 120.

Peavey Invective MH 20W Mini Tube Amp Head  

Inspired by one of the most in-demand high-gain amps on the market, the Peavey Invective MH outputs at much lower power levels than the 120, sacrificing absolutely nothing in tonal character but benefitting substantially from both lower weight and smaller size.

Peavey Invective MH 20W Mini Tube Amp Head Features:

  • 2x EL84 Power Tubes & 3x 12AX7/ECC83 Preamp Tubes
  • Clean Channel & Lead Channel with 3 band EQ
  • Master Resonance and Presence Control
  • Footswitchable Tight, Gate & Boost on Lead channel
  • Footswitchable Buffered FX Loop
  • Tube Status Indication (T.S.I.) Circuit
  • Impedance, Ground Lift & Speaker Defeat Switch
  • MSDI Output with XLR
  • USB & Headphone Outputs
  • Attenuator Switch for 20W, 5W or 1W Output Power

Versatile Mini-Head Form Factor

Making it the perfect choice for small gigs, studio setups and practice performances, this travel-friendly amp head is perfect for the musician on-the-move.

Specifically designed to accommodate more modern, pedalboard-centric players - the clean channel is the perfect blank canvas for your pedal-board experiments, whilst the high-gain channel is based on the legendary 6505 amp, highly regarded as helping to shape today's hard rock sounds!

With this exceptional tonal versatility at your fingertips wrapped up in a mini-head form factor, this incredibly versatile all-rounder is the perfect companion for the road, guaranteed to go the distance! So, why not visit one of our 15 Nationwide Stores today where one of our In-Store Experts would be more than happy to walk you through this feature-filled guitar amp head!
