The Plexsound Psychonote BW10 is manually assembled (point-to-point, hand-wired), built in tube technology, using the best materials and components for an electric guitar minimum-feature combo amplifier.
A perfect solution for practicing, sessions, recording the guitar both in professional and home studios, performing in small halls and clubs.

No compromise and no “bells and whistles”

  • an all-tube audio signal path
  • GZ34 tube rectifier
  • top quality elements
  • custom designed transformers
  • spring reverb
  • manual, point-to-point assembly
  • compact structure, small size

The Plexsound Psychonote BW10 design is reminiscent of the early guitar amplifiers built in the 1950s and the 1960s. It is a classic tube amp application with a push-pull output.

Circuit-wise, it is a minimalist design that aims mainly to achieve a full “tube” sound.

Distortion is obtained chiefly at the output of the power amplifier, which is signature for amplifiers, commonly dubbed as VINTAGE.

Two independent channels (foot switch operated) enable the guitarist to control both clean and distorted channels. The combo is equipped with a spring reverb (a tube-built reverb system).

The Plexsound Psychonote BW10 uses only selected tubes from renowned manufacturers.

The Plexsound Psychonote BW Signature 10

  • a fully-fledged “vintage” amp – turn up the volume to wake up the beast
  • a universal device that enables you to create your own sound
  • clear sounds are selective, bright and full-bodied, rich in bell like tone
  • creamy overdrive – very clear and sharp, typically British
  • the amp has clear top and full lower ranges, without any loss of selectivity even at maximum overdrive
  • very good natural compression

The Plexsound Psychonote Bartosz Wojcik Signature 10 has been created in cooperation with composer and guitarist Bartosz Wójcik.


An exquisite amp cabinet made of precious sycamore

  • seasoned sycamore wood
  • each cabinet has its individual character like a man

The amplifier cabinet is made of sycamore wood. Due to its excellent acoustic qualities sycamore is widely used in the construction of instruments such as guitars, strings, drums, etc. Each cabinet is finished in an individual (custom-made) way.

But wood is a difficult material, and unlike chipboard or plywood, it responds to environmental changes (humidity, temperature). As a result, the guitarist has to pay more attention to how they operate the amplifier, treating it more as an instrument than a typical electronic device. But the device will reciprocate offering sounds unavailable from today’s mass-produced designs.

Legendary Celestion Vintage G10

  • ceramic magnets
  • the same voice coil design as the Celestion Vintage 30

The dimensions of the Plexsound Psychonote BW10 cabinet provide ideal space for 10” speakers. The Vintage G10 speaker, successor to the Vintage 10, offers sound similar to the iconic 12″ Vintage 30 speaker. When you connect the combo to external speakers (2×12″ G30 or 4×12 G30″) you’ll get powerful sound and a much larger volume while maintaining a similar sound climate.

Point-to-point assembly

  • minimizes parasitic capacitance
  • eliminates the risk of circuit path cracks, often occurring in printed circuit boards
  • ease of maintenance

An assembly based on printed circuit boards enables efficient space management and mass (cheap) production. In the 1950s and 1960s guitar amplifiers were assembled in point-to-point technology. That was one of the elements that positively affected the sound of the amplifier. Why?

Circuit paths are run in parallel along one plane, close to one another. This produces relatively large capacitance between them, as if another line of capacitors were added to the original circuit. This capacitance dampens higher harmonic range of the acoustic signal which has a significant impact on the musical message. Point-to-point wiring minimizes this phenomenon, the spacing between components and connections is relatively large and not regular.
