Description

The Peavey Classic 20 MH is a versatile addition to any musician's gear, embodying the quintessential blend of vintage and contemporary tones. This all-tube, 20W mini amp head is revered by blues, country, and rock players for its flexibility and stellar performance. Powered by two EL84 power tubes and three 12AX7/ECC83 preamp tubes, it delivers clean, warm tones and overdriven rock leads with ease.

The dual channels follow the same gain structure and voicing of the Peavey Classic series amplifiers, offering a wide range of tonal options. These channels share a 3-band EQ, lush reverb, and an effects loop, all of which are footswitchable, allowing you to easily switch tones on the fly. The Tube Status Indicator (T.S.I.) is a standout feature that alerts players of power tube status and identifies which tube needs to be replaced, ensuring your amp is always gig-ready.

Designed for both live performance and studio recording, the Classic 20 MH is equipped with a Microphone Simulated Direct Interface (MSDI) with XLR output and USB out. The rear panel also includes a speaker defeat switch and a 3-position power attenuator switch, making it a perfect companion for studio environments.

Key Features:

  • Two EL84 power tubes and three 12AX7/ECC83 preamp tubes
  • Dual footswitchable channels with 3-band EQ

Critic Reviews

Peavey Classic 20MH & ValveKing 20MH review

guitar.com

Peavey’s Classic 20MH shines in its compact form, delivering genuine all-valve tones in a portable package. Its versatility, with features like switchable gain boost, digital reverb, and power attenuation, makes it ideal for varied performance settings. However, the amp's reverb effect can be off-putting, and low-light situations render its control panel nearly unreadable. Despite minor setbacks, it’s a robust choice for those seeking a classic rock sound with modern conveniences.
