EBS BILLY SHEEHAN ULTIMATE SIGNATURE BASS OVERDRIVE PEDAL

An "Ultimate" evolution in the Billy Sheehan lineage

The Signature Drive Ultimate carries forward the spirit of the Standard and Deluxe versions: a saturation pedal designed for bass, capable of adding grit while maintaining the essential foundation and precision in a band setting. This "Ultimate" version goes further by adding tools tailored for the demanding musician: a separate Boost, ultra-low noise switches, and especially sound-shaping options that allow adapting the pedal to your instrument, amp, and playing style.

The concept remains faithful to Billy Sheehan's approach: controlled, articulate distortion that doesn't erase the low end, with the ability to blend clean and saturated signals clearly to keep the "punch" and attack whether using a pick or fingers.

For which bassist and styles?

This bass overdrive pedal targets bassists who want a crafted and immediately usable sound, from rock to hard rock, including metal, fusion, and all genres where the bass needs to hold space without masking the kick drum. Thanks to the effects mix and separate clean/saturated loops, it suits both those seeking a subtle permanent "edge" and those going for heavily loaded lead-bass tones.

In the studio, it facilitates tracking by preserving note clarity and controlled dynamics. Live, it becomes a true control center: you can switch from subtle grit to more radical saturation via the Boost while maintaining a solid and consistent foundation in the mix.

Controls, modes, and innovations: a pedal designed as a mini-rig

The Billy Sheehan Signature Drive Ultimate combines 3 simultaneous effects and offers performance-oriented ergonomics. It includes essential saturation controls (Drive, output level, tone), plus advanced controls: effects mix to balance clean/saturated signals, and an integrated compression section with 3 modes (off, mid, high) and advanced threshold and level settings. The compressor can reach up to a 5:1 ratio (max), useful for stabilizing attacks and thickening notes during more aggressive passages.

The Ultimate version stands out with several major additions: a Drive Boost switch adding a gain stage, a Phase inverter that changes how the distortion reacts and "sits" in the sound, and a Hi/Lo frequency selector that shifts the Tone filter's spectrum towards bass or treble frequencies. The result: you can go from a thick, round grit to sharper, more present textures without changing pedals.

Finally, the replaceable op-amp opens the door to customization rarely seen on this type of pedal: by swapping the chip, you can markedly alter the saturation's character. Add to this very silent and precise magnetic switches, and you get a compact, reliable pedal built for a modern pedalboard.

The sound

The Signature Drive Ultimate delivers a dense, articulate, and controlled saturation with a real focus on preserving fundamentals. The clean/saturated blend helps maintain attack and definition while adding a grain that "sticks" to your playing: the harder you play, the more the pedal responds with character. The Tone section, enhanced by the Hi/Lo selector, allows targeting either an ideal mid presence to cut through a rock mix or a more biting and incisive sound when seeking a modern distortion. With the phase inverter, you can also adjust the overall feel of the distortion and its interaction with the rest of your signal chain.
