The Bad Mofo Bass Overdrive Preamp is a pedal designed for bass players who love dirty, gritty tones. It is based on the famous Ezekiel 25-17 and now comes in a smaller 1590B version for those who prefer a compact pedalboard.The updated 2022 version features a separate daughterboard for the rotary switch, making it easier to mount the switch level with the pots for a clean enclosure. This design change improves the overall aesthetics and functionality of the pedal.The DRIVE and LEVEL pots allow you to control the amount of dirt and volume, giving you the flexibility to dial in your desired tone. The TREBLE knob acts as a low pass filter, cutting the top end frequencies to add a touch of fizz to your sound.What sets this pedal apart is the four-way rotary switch, which offers four distinct clipping options: Silicon, Germanium, LED, and clipping bypass for extra crunch and minimal clipping. This variety of clipping options allows you to experiment and find the perfect tone for your bass.To maintain the integrity of your dry signal, the Bad Mofo features a highly effective buffered BLEND control. This control allows you to blend in as much dry signal as you desire, ensuring that your original bass tone shines through.While the Bad Mofo may be the only bass dirtbox you need, it’s important to note that the rotary switch will typically have a long shaft that needs to be cut down to size. Additionally, the pedal now comes with a 4559 op-amp instead of the previously used 4562 op-amp, as the latter is no longer available.Overall, the Bad Mofo Bass Overdrive Preamp offers bass players a versatile and powerful tool to shape their tone and add some serious dirt to their sound.
