Pure Analog Bass Tone
The TAR-20B uses a pure analog preamp design with a wide tonal range, giving bassists responsive control over their sound. Its gain circuit can move from clean and articulate tones toward heavier, saturated textures, making the amplifier suitable for funk, rock, modern bass, and other styles requiring flexible tonal character.
Flexible 3-Band EQ
The dedicated Low, Mid, and High controls provide straightforward tone shaping for different basses, playing styles, cabinets, and environments. The EQ operates at 70 Hz, 800 Hz, and 3.5 kHz respectively, with a ±9 dB boost or cut range for precise adjustment.
Built-In Chorus Effect
The integrated chorus circuit expands the tonal possibilities of the TAR-20B by adding depth and movement to the bass signal. It can be used to create wider, more atmospheric sounds while keeping the overall setup simple and portable.
Silent Practice and AUX Jamming
The headphone output features a built-in cabinet simulator, allowing bassists to practice privately without connecting an external speaker cabinet. The AUX input provides an easy way to play along with backing tracks, music, or other external audio sources.
FX Loop and Speaker Connectivity
The dedicated effects loop allows external effects and processors to be integrated into the amplifier's signal path. For larger setups, the speaker output supports compatible 4-ohm and 8-ohm bass cabinets, providing useful flexibility beyond the compact amplifier head itself.
Compact and Portable Design
Measuring only 180 x 95 x 35 mm and weighing approximately 816 g, the TAR-20B is easy to carry between home, rehearsal rooms, studios, and small performance spaces. Its compact size also makes it convenient to keep in a gig bag or as a lightweight backup amplifier.
