The latest version of the B7K, "B7K V2," which allows you to select the mid frequency, is now available! An analog preamp for bass that produces a wide variety of sounds. It utilizes the powerful and dynamic saturation circuit of the B3K overdrive, adds a powerful 4-band equalizer, and is equipped with a balanced line driver output for unparalleled usability. It takes all your bass sounds to the next level, whether in the studio or live.control Level: Adjusts the volume of the overdriven signal. Drive: Adjusts the saturation of the overdrive. Blend: Adjusts the ratio of the clean signal to the overdriven signal. The clean signal always remains at unity gain, and the overdriven signal can be adjusted with the Level knob. Using the Level and Blend knobs in combination allows for fine tuning. Grunt switch: Changes the strength of the low frequencies. You can choose from three bass boosts and levels before the clipping stage: Fat, Thin, and Raw. Attack Switch: This switch works similarly to the "Ultra Hi" option found on many bass amps. It lets you adjust the amount of high frequency intensity when distorted. The Boost setting provides a clearer, more present sound. The OFF setting provides a warmer, more mellow sound. Low Mids Switch: You can choose the Low Mid frequency to be 500Hz or 1kHz. Hi Mids Switch: You can choose the Hi Mid frequency to be 1.5kHz or 3kHz. Low: ±12dB@100Hz Low Mid: ±12dB@500Hz or 1kHz Hi Mid: ±[email protected] or 3kHz Treble: ±12dB@5kHz Direct Output: The balanced XLR output allows you to send your bass directly to a PA or studio mixer and features a ground lift switch. Parallel Output: Passes the input signal through. This is useful when creating a parallel system.
