Vahlbruch BBQ-XL Dual 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".
The BBQs buffer eliminates impedance matching problems and avoids annoying loss of treble and dynamics that can occur with long cables and effect pedal chains. The BBQ is the perfect booster to overdrive an amp's input stage, but it can also help to clear up a crunchy amp (minus booster). The volume can be adjusted over a wide and practical range from -8dB to +16dB.
The extremely effective equalizer section of the BBQ (+/-15dB for each band) is so versatile that only the user's imagination sets its limits. It allows, among other things, to comfortably match signal levels or balance different instruments better. You can also add an additional sound option or gain stage to your overdrive pedal, e.g. with reduced bass and boosted mids for more punch and clarity. If the BBQ is used after an overdrive pedal, it can of course also act as a volume boost for lead parts or as a dedicated sound shaping tool for your specic drive sound.
By using the internal DIP-switch you can select between an active high-end buffer circuit or true bypass operation. The LED "Buffered Output On" indicates if the buffered bypass mode is activated. These examples are only a small part of possible applications of the BBQ pedal. Especially in complex setups, the BBQ makes full use of its extensive features and fexibility and not only provides a better signal quality, but creates essentially more variability of the complete pedal board. The BBQ can be used in front of the amplifier as well as in effect loops. Its operation is always intuitive and self-explanatory, and the original circuit design delivers high-end audio performance with a signal-to-noise ratio in studio quality.
This pedal is equipped with our unique "MagTraB" switching technology: Inside the button a magnet is integrated which position is measured by a sensor on the circuit board. If the button is now moved, e.g. if it is pressed downwards, the position of the magnet will also change. The sensor measures this change without any mechanical contact to the button and the information is send via a micro-controller to a gold-plated relay, which then does the actual audio signal switching.
