Description

The warmth and powerful sound of a tube amp is outstanding.
James Demeter's masterpiece micro tube amp head!


The realistic, organic analog sound that only genuine vacuum tubes can produce and the powerful Class D output power amplifier have been perfectly matched and given the ultimate tone by the craftsmanship of master James Demeter.

The preamp circuitry is based on the legendary VTBP-201 tube preamp, originally designed for Leland Sklar. It features high-quality components, a DC filament, a full 220V high-voltage supply, and four-band passive tube tone controls (Treble, Middle, Bass, and Presence). It also features three modes: Dark, Normal, and Bright, allowing you to change the overall color of the amp tone. This allows for a wide range of expressive possibilities and high-end sound quality.

Every manufacturing process is meticulously hand-wired in our US workshop. Each unit is meticulously tuned, setting it apart from mass-produced products. This is a high-end boutique bass amp that allows you to enjoy the authentic charm of a true bass amp.

The pre/post switchable DI output (Balanced Studio Out) can be optionally upgraded to the same "Jensen transformer" specification as the company's "Tube Direct" DI.
Additionally, while the standard Demeter Bass 400/800 models are Tolex style, you can also order a special cage-style design.

Its compact design, resembling the style of a large head amp, and its light weight of just 3.5kg are enough to make you want one, but the realistic tube sound it produces, despite its cute appearance, is a testament to the master Demeter's skill and experience. It's also surprisingly versatile, and it seems to maximize its potential with JB and PB. The size is also great, making it easy to use for both live performances and recording.

Please try it out for yourself!
