Product Details

The Demeter VTBP-201 Tube Bass Preamp is the legendary tone machine that revolutionized modern bass amplification. Designed by audio visionary James Demeter, this classic 1.5U rackmount preamp brings the warmth, punch, and clarity of high-end studio gear right into your bass rig. It is the secret weapon used on countless hit records and major world tours.

Hand-Wired Studio Quality

At the heart of the VTBP-201 is an all-tube, hand-wired circuit that runs on real high-voltage studio specs. It uses two premium 12AX7 tubes to deliver an incredibly fat, touch-sensitive response. Whether you play a vintage passive jazz bass or a modern high-output active 5-string, this preamp captures every detail of your playing with massive headroom and zero harshness.

Musical EQ Control

The VTBP-201 features a classic three-band rotary EQ based on traditional passive tube designs. The controls are highly interactive, allowing you to easily dial in everything from deep, pillowy Motown lows to crisp, articulate slap tones.

• Treble Control: Adds smooth, glass-like air without high-end hiss.
• Middle Control: Cuts or boosts the crucial frequencies that help you cut through a dense band mix.
• Bass Control: Delivers a tight, room-shaking low end that stays focused and never gets muddy.

Deep and Bright Tone Shaping

To give you instant tonal flexibility, the VTBP-201 includes two dedicated toggle switches:

• Bright Switch: Enhances the upper harmonics, adding sparkle and bite for slap styles or fresh strings.
• Dark Switch: Rolls off the high frequencies for a warm, vintage vibe that mimics classic 1960s tube flip-tops.

Built Like a Tank

Housed in a rugged, heavy-duty steel chassis, the original VTBP-201 is built to survive decades of touring. With its distinctive 1.5-space rack design and minimalist front panel, it represents a golden era of boutique bass gear. It is the ultimate centerpiece for players who refuse to compromise on their tone.
