FOREWORD
The VT-300B was designed for those who love the great vintage tone and gentle acoustic color of the old tube amplifiers. This is a hand-crafted amplifier built with modern construction techniques and reliable printed circuits by people who care about sound and quality.
You have purchased what we feel is one of the finest bass amplifiers in the world. This rack mountable package houses modular circuits made with superior components and designed for years of trouble-free service.
Your amplifier was designed, engineered and manufactured equivalent to aircraft vibration standards and housed in a one-piece aluminum case with steel top to ensure maximum reliability. The PCB design allows quick repair in the field should such a need arise. Just as a skilled craftsman needs good quality tools that won't let him down on the job, so does a good musician. We hope you enjoy the tool we’ve created. Have fun; play low!
Please read this manual in its entirety before operating your new amplifier. Failure to do so could result in misuse or damage. We’ve taken the time to write it, which was a lot longer than the time it will take for you to read it. Help us help you by taking a few moments to learn how to properly use your new amp. You’ll be glad you did!

FRONT PANEL FEATURES
Input Jacks – Designed to accept a standard _” mono phone plug. The
Passive jack is for use with low output basses and passive basses. The active jack is for higher output basses with active electronics.
Overdrive Switch – This switch shifts the amplifier into an ultra-high gain mode, suitable for a wide range of sound textures – from clean to fat and all the way to saturated – with exact control throughout the entire range. This works in conjunction with the Input Gain control. The higher the Input Gain control is set, the more distortion can be generated. This function is also on the foot switch.
Gain Control – This sets the channel gain for the system and lets you match the output level of your instrument to the amplifier. In the Overdrive mode the Gain Control setting determines the amount of overdrive available.
Multi Q Equalizer – The Multi Q Equalizer circuit uses a four band parametric E.Q. It has preset centers, and fixed Qs or bandwidths that vary with center frequency. This is a very user-friendly set up. You can fine tune your sound very quickly using this simple system. The center frequency spacing follows the natural content of the music and fits with the instrument very well.
Master Tone Controls – The Master Bass and Treble controls are provided for very fast E.Q. of the system. They also combine with the Multi Q for even more tone shading. These are Hi-Fi-type shelving filters and effect a broad range of tone.
Master Level Control – This controls the final drive to the amplifier. Use this to control your stage level. About mid point on the control should be normal for most playing situations.
Compressor Active light – This indicates the activity of the compressor. When the LED lights up the compressor is functioning.
Standby – This switch sets the amplifier in the standby mode. The filaments stay powered up but the hi voltage to the output tubes is removed so that they can not operate. This extends the life of the tube and allows for less stress during start up and power down.
