Peavey Classic 20 Guitar Amplifier Head - Tweed

The Peavey Classic 20 - Compact All-Tube Power with Vintage Soul

Classic Tube Tone in a Portable Package

The Peavey Classic 20 MH head delivers all-tube character in a compact tweed-wrapped chassis built for real-world performance. Featuring two EL84 power tubes and three 12AX7 preamp tubes, it channels the warm, harmonically rich voice of classic American tube amps. With 20 watts of genuine tube power and a switchable attenuator for 5W and 1W modes, this head is equally at home on small stages, in the studio, or for late-night practice.

Versatile Dual Channel Layout

Designed for tonal flexibility, the Classic 20 sports two footswitchable channels (footswitch not included): Rhythm and Lead, each sharing a three-band EQ section for intuitive tone shaping. A footswitchable volume boost adds punch for solos, and lush onboard reverb enhances depth. Whether you’re going for spanky cleans or searing leads, this amp responds dynamically to your playing and pickup selection.

Modern Recording and Practice Features

Beyond vintage tone, the Classic 20 MH is loaded with modern conveniences. Its rear panel houses a USB recording output and Peavey’s MSDI XLR out for cab-simulated DI tones, perfect for silent recording or live applications. A headphone out and speaker defeat switch enable private playing without waking the neighbors. The included impedance selector ensures compatibility with 8 or 16 ohm cabinets.

Built-In Tube Monitoring and Effects Loop

Peavey’s T.S.I. (Tube Status Indication) system monitors the EL84 power tubes, giving visual feedback via LEDs, green for good health, red for replacement or service. A fully footswitchable buffered effects loop lets you integrate your favorite pedals cleanly, while the Classic’s solid construction and smart design ensure road-worthy reliability.

Light Wear, Fully Functional

This unit shows only light wear consistent with gentle use and is fully operational. It includes a fitted cover and IEC power cable. The footswitch is not included, but compatible Peavey 2-button switches are readily available if needed. It’s a fantastic value for players who want boutique-style tube tone in a reliable, gig-ready form.
