One of the main things that makes this amp special is the sheer vastness of pure valve power on tap from the twelve valves it houses. Consequently, we didn’t want to dilute any of this natural purity by oncorporating unnecessary features and controls. For this very reason, only the essential fron panel controls have been included.

This said, the VBA-400’s 3-band passive EQ network for Bass, Middle and Trebl has been designed so that it offers you all the tonal adjustment you’ll need. Furthermore, this tonal network can be totally changed by means of the 3-position Contour switch which reconfigures the mid range as follows:

Contour position 1

Drops the low mids and creates a rounder, fuller, fat bottom end.

Contour position 2

Boosts the mid range, giving greater edge and aggression to your sound.

Contour position 3

Moves the mid range higher than you would normally expect on a bass amplifier. This adds an aggressive twang while leaving the essential body of your tone intact, making it ideal for percussive styles such as slap bass.

Further tone control is provided by Deep and Bright switches.

Other essential features include Active and PAssive inputs, an XLR DI Output, complete with switches for Earth (ground) Lift and pre/post EQ selection, a Series FX Loop and a High/Low Fan Speed switch to ensure the valves are kept at a safe operating temperature. There is also a Tuner Mute function.
