High quality electronic based on carfully selected electronic components.
A compact design with high output power.
  1. Loaded with a high power high efficiency Celestion G12H75 Creamback 12" loudspeaker. We dropped the Warehouse (WGS) ET-90 loudspeaker we had originally selected further to a number of comparative test sessions we ran in 2024 with few partner guitarists. These tests confirmed that the two loudspeakers are very similar in tone / sound signature. Yet, all guitar players agreed that the Celestion speaker has superior definition, better ability to reveal the slight details of an instrument and artist's sonic signature sound.

    This loudspeaker has a very large ferrite motor and a beefy voice coil resulting in a great headroom, monster feel and large power handling. If you've been looking for classic British tone with an "open" feel and a lot of power and dynamics, the Celestion G12H75 Creamback is your new favorite.

    Simplicity best serves sound quality: this product's features are purposely limited to prevent complex and numerous electronic stages from altering sound quality and raising power consumption (See company environment charter on site welcome page).

    Laser engraved aluminium enclosure.

    Automatic tube pre-heating circuit.

    Two stage high gain and low noise tube based preamp section providing a very clean, detailed and transparent sound. Boost mode provides a crunchy to lightly saturated sound.

    Inputs/Outputs: One 1/4" input jack connector + one 1/4" headset output jack connector on the front panel. On the back panel: Two 1/4" loudspeaker output jacks + two 1/4" jack connectors for the effects loop (Send/Return).
