Mad professor Ruby Red Booster

The Ruby Booster is a combination of 2 boosters and a buffer. The 2 boosters are based on our designer Björn Juhl's Red Trebler and Red Rooster Booster, and are connected in that order, in addition to a master volume. The Ruby Red Booster can therefore be used as a treble booster, a clean boost, an overdrive or any combination of these 3 effects. Inside, there's a selector switch to engage a high-quality buffer, to avoid the loss of signal and definition associated with long cables or many pedals. With this selector on the right (towards the input), the buffer is activated. On the left, true bypass is activated.
The treble booster is set to carefully selected high frequencies with a special bandwidth and optimized curve for bass cutoff. It is controlled by the Treble control and can go up to 15dB. To use the Ruby Red Booster as a treble booster only, turn the Boost control all the way down, turn the Master control all the way up, then dose with the Treble control.
The boost circuit, controlled by the Boost control, is designed to saturate the amp's inputs, and is capable of very heavy overdrive thanks to its 40dB boost. The booster is calibrated to produce musical distortion even at high settings. To use as a booster only, set Treble to minimum, Master to maximum, then dose with Boost. The Master setting allows you to control the overall volume of the 2 boosters, as well as to make
