The Microtubes X Ultra pushes the boundaries of bass processing by building upon the acclaimed X7 foundation with four game-changing additions that redefine what’s possible in a compact pedal format. This powerhouse maintains all the beloved controls from its predecessor, allowing precise frequency selection for compression and saturation across low and treble ranges, whilst introducing new layers of sonic flexibility that make it an indispensable tool for today’s bassist.
At its core, the unit splits your signal into Low and High bands through sophisticated filtering. The Low Pass filter sweeps from 50Hz for pure sub-bass content up to 500Hz to retain clean midrange character, with the Low band responding beautifully to the onboard compressor for enhanced bottom-end punch. Meanwhile, the High Pass Filter shapes your distortion character from 100Hz for thick, fuzzy saturation through to 1kHz for razor-sharp definition.
The comprehensive 6-band EQ system provides exceptional tonal sculpting capabilities, ensuring you can sit perfectly in any mix regardless of the accompanying instruments. A Master slider offers convenient overall output control for quick level adjustments. Additionally, Darkglass’ renowned cabinet simulation comes loaded with premium impulse responses, giving you authentic mic’d cabinet tones when running direct to DI or PA systems, with the option to bypass when desired.
