VT1-Pro-Bass-Drive

 

The VT1-Pro-Bass-Drive from DHA is a hand built valve Overdrive effects pedal which uses a 12AX7 (ECC83) pre-amp valve to provide true valve tone, the tone generated has to be heard to be believed! The VT1-Pro-Bass-Drive is designed and voiced for bass players looking for subtle clean to crunch valve tone for blues and rock. This model in our VT1 range has a 3 band active EQ with mid range Q, a XLR balanced DI out plus headphone amp and line in.

 

There is a "cool blue" back light which acts as a power on light and it is visible via the valve vent holes. There is also a blue LED for effect on.

 

Overdrive is achieved by using both gain stages in the 12AX7EH valve/tube to generate the classic valve pre-amp overdrive tone plus a clean op-amp boost is available for extra output volume. It is great with modern solid state amps by adding valve warmth and fantastic with valve amps by overdriving with a true valve signal path. The VT1-Pro-Bass-Drive sounds great when plugged directly into a desk or a digital recording setup via the low noise XLR balanced DI output.

 

The Gain and Level controls let you select that tone you been looking for! And don't forget the volume and tone on your bass which will react well with the VT1-Pro-Bass-Drive just like a real valve amp/pre-amp. There is a true By-Pass Foot Switch which is used to select the Overdrive and EQ part of the circuit but the DI remains on all the time. This means you can use the VT1-Pro-Bass-Drive to DI your other effects or just the bass with or without adding the VT1's valve warmth.

 

The 3 band active EQ provides +/- 15dB of cut and boost in each range plus the mid tone control has a Q control so you can adjust the sweet spot frequency.

There is a bright switch on this model which boosts the treble when selected without losing the bottom end. There is an i/p pad control which is useful when using active or high output pickups.

 

There is also a "Colour" switch and Colour pot which selects negative feedback to the circuit, this means more gain and compression. At higher gain settings Colour can push the effect into an almost fuzz tone.

 

The tone is pure valve/tube, fat and warm and completely different to silicon effects pedals which tend to fizz and compress the signal. Unlike silicon pedals you can use the volume control on your bass to control the amount of distortion you want, just turn it up for the solo.

 

There is a selectable boost function. This adds additional clean output volume to the valve signal using a low noise op-amp. This function is very useful when very low levels of gain are required for clean but fat valve tones. The boost control allows the user to set the boost level.

 

The output of the VT1-Pro-Bass-Drive is connected to a standard 1/4" jack for use with an amp and an XLR balanced DI connector which is in parallel. This means both outputs can be connected at the same time, so the 1/4" might go to the amp for the stage back line and the DI to the PA or desk. The DI is also intended for studio recording as the pedal is really a valve/tube pre-amp so will add warmth to any set up. There is a DI ground lift switch which is useful if a ground loop hum occurs.

 

There is a headphone amp built into this pedal which is intended for quiet practice when used with headphones but the output will also drive a set of stereo speakers at 1W+1W. There is a line in socket for connection to a stereo line level signal such as a CD player, MP3, phone, etc. This signal is mixed with the headphone signal so you can play along to your favourite tracks.  

 

The VT1-Pro-Bass-Drive runs from a 9-12VDC 300mA (12VDC 1000mA recommended) supply via a standard centre negative 2.1mm socket. A suitable 12VDC @1000mA power supply is supplied with the pedal if it is ordered via this website

 

The VT1-Pro-Bass-Drive is totally hand built using a quality PCB. There is a one year return to manufacturer guarantee which covers parts and labour in case of failure with each unit. There is also a user manual.
