Valeton TAR-20B 20W basgitaarversterker top

The Valeton TAR-20B redefines compact bass amplification with a solid-state preamp and Class D power section that deliver 20 watts of punchy, articulate tone from a chassis small enough to fit in a gig bag. Unlike bulky bass heads that dominate your rig, this mini head offers a full 3-band active EQ, an effects loop, and a dedicated headphone output—making it equally at home on stage, in the studio, or during late-night practice sessions.

Highlights

• 20W RMS output into 4 ohms minimum—drives most bass cabinets with authority
• 3-band active EQ (Bass, Middle, Treble) plus Gain and Volume for precise tone shaping
• 1/8" auxiliary input and headphone output for silent practice with backing tracks
• Effects loop (send/return) integrates your pedalboard seamlessly
• Compact metal chassis with black/grey finish—built for the road

In daily use

Plug in your bass and the TAR-20B responds with a clean, dynamic voice that flatters both passive and active pickups. The active EQ lets you carve out mud or add growl without external pedals, while the effects loop keeps your modulation and time-based effects pristine. Connect a 4-ohm cabinet for full output, or use the headphone jack for direct monitoring—the auxiliary input lets you jam along to tracks from your phone. The 18V DC power supply (center positive) is included, so you're ready to play out of the box.
