Large physically sized paper in oil signal condensers are combined with modern, small physically sized capacitor technology in a 12AX7 tube preamp circuit. The 12AX7 preamp schematic is a simple Class A type. The secret behind the use of the large physically sized paper in oil capacitors is that they have a tendency to reduce transmission of high frequency components of the amplified signal, said large physically sized capacitors having certain substantial stray capacities to ground. Generally speaking, the higher the voltage rating is, the larger in physical size of the paper in oil capacitor. If a 500-630VDC paper in oil capacitor is used the tone suddenly comes to life. For over 50 years the technology has existed, but it was never discovered until recently. Try this new product! Digital effects never sounded so good as when used in combination with the completely analog Nitewalker Preamp! It's here - a bargain at twice the price - The Nightwalker Bass Guitar Tube Preamp!
