Vanderkley Amplification is a small company in the Netherlands, which specializes in designing and building high-end amplifiers and loudspeaker cabinets for bass players. When Vanderkley started in the year 2005, the main goal was to produce high quality, superb sounding bass speaker enclosures and provide excellent service. In 2007, Vanderkley has designed some high-end bass amplifiers to match.
The heart of every Vanderkley bass setup is the VA615 dual tube bass pre amplifier. This is a very sophisticated but easy to use all tube bass preamp. The VA615 is completely hand wired and has warmth, dynamic range, rich and detailed tone, which only tubes can provide. It features a subtle passive 5-band tone control designed by Ir. Menno van der Veen.
Some other features are; separate inputs for passive and active basses with mute to tune function, a parallel effects loop which can be mixed from zero to 90% effect to your output, a phase correction switch so no frequencies are lost when the loop section is activated, a floating transformer balanced D.I. which is absolutely silent.The preamp operates very quiet; hum and noise is extremely low, so it is also perfectly suitable for use in a recording studio. The VA615 is completely hand-made by Marc Vanderkley.
