Vahlbruch BBQ-XL: Buffer, Booster, Equalizer

The Vahlbruch "BBQ-XL", which is the big brother of the "BBQ"-pedal, is a super versatile dual channel transparent clean boost, equalizer and high-end buffer, housed within a compact and pedalboard friendly enclosure. It perfectly serves as a booster to push your amp harder or it can also be set to clean up the tone of a crunchy amp, thereby transforming a single channel amp into a versatile 3 channel monster! The "BBQ-XL" can also help to adjust different guitars to your amplifier without turning a knob during the show. These are just two examples of a magnitude of applications! With its switchable high-end buffer / line-driver circuit, the "BBQ-XL" also eliminates impedance adjustment problems and therefore preserves your signal without changing or coloring your original tone even when using long cables and effect chains. The Vahlbruch "BBQ-XL" is also suitable for bass and acoustic guitars! 
Each channel features its own volume and active 3-Band EQ controls. The volume can be adjusted over a wide range from -8dB to +16dB, and each band of the active equalizer has a boost/cut range of +/-15dB for a precise adjustment of bass, middle and treble. In my unique circuit, the unwanted interaction between the individual EQ-bands is eliminated and each control does not interfere with the other. Via an internal switch, you can choose to have the "BBQ-XL" operate in true bypass or buffered bypass mode. An LED indicates the activated buffer mode as "Buffered Bypass".
