Vox Valvetronix VT20+ 20W Combo

This second hand guitar amp is in great condition.

The Vox VT20+ is a 20-watt hybrid modeling amp that combines real tube warmth with digital versatility. Featuring 33 amp models, multiple effects, and a 12AX7 tube-driven preamp, this amp is designed for home practice, recording, and small gigs. It delivers everything from classic Vox chime to modern high-gain tones, making it an attractive option for players looking for flexibility without sacrificing warmth.

Build Quality & Design

The VT20+ has a classic Vox look, with the iconic diamond grille cloth and black tolex finish. It’s compact and lightweight, making it easy to carry around for rehearsals or small gigs. The top panel controls are well laid out, but menu diving is sometimes necessary when tweaking effects or amp settings.

A big improvement over previous Valvetronix models is the power level control, which lets you adjust the wattage from 1W to 20W, allowing for cranked tones at low volumes—a great feature for home players.

Tone & Sound Quality

The VT20+ stands out from standard digital modeling amps because of its Valvetronix hybrid design, which combines a real 12AX7 preamp tube with digital amp modeling. This gives it a warmer, more natural feel compared to fully digital amps.

It features 33 amp models, covering everything from:

• Classic Vox cleans (AC30, AC15)
• Fender-style bluesy breakup
• Marshall and Mesa-inspired high-gain tones

The clean and low-gain tones shine, with chimey, dynamic response. The mid-to-high gain settings sound decent, but can sometimes feel a bit processed or compressed, especially at higher volumes.

The amp also includes 25 effects, including reverbs, delays, modulations, and compressors. They sound great for a built-in selection, but lack deep tweakability compared to standalone pedals.

A major plus is the adjustable power control, allowing for saturated tube tones at bedroom levels.

Usability & Features

The VT20+ is easy to use, with dedicated knobs for gain, volume, tone, and effects selection. However, the preset selection and effects customization require some menu navigation, which can take time to master.

Other notable features:

• Built-in tuner – Convenient for quick tuning.
• Aux input & headphone output – Great for silent practice.
• Power level control – Lets you adjust wattage from 1W to 20W.
• Optional footswitch support – Allows for hands-free preset switching.

For home and small studio use, this amp is packed with useful features. However, for live use, switching between presets could be smoother, especially without the footswitch.

Pros & Cons

Pros:

• Authentic tube warmth with hybrid Valvetronix design
• Wide variety of amp models and effects
• Power level control for cranked tones at any volume
• Great clean and mid-gain tones
• Compact and lightweight for portability

Cons:

The Vox VT20+ is one of the best small hybrid modeling amps for home practice and recording, offering great tone variety, real tube warmth, and adjustable power levels. While it may not fully replace a high-end tube amp for gigging, it delivers impressive tones and versatility for the price.

If you want a small, affordable amp with classic Vox sounds, built-in effects, and real tube feel, the VT20+ is a solid choice.
