Description

Darkglass Electronics Microtubes X7 Bass Preamp Pedal

Unleash the power of your bass guitar with the Darkglass Electronics Microtubes X7 Bass Preamp Pedal. This versatile bass preamp pedal offers a rich and full sound, perfect for musicians who crave aggressive and punchy tones. The secret to its dynamic range lies in the unique dual-filter design. Before driving your tone, the Microtubes X7 splits your signal into two, feeding it through two variable filters. This allows you to shape your sound, creating a unique drive tone that combines just the right amount of boom and bite.

With the 4-band graphic EQ, you can tweak your midrange character to perfection, ensuring your bass holds its own in any mix. A variety of routing options, including a direct output and parallel output, offer flexibility for both stage and studio use.

This pedal doesn't just distort your bass signal, it enhances it, providing a powerful, tight, and defined tone for any bass guitar.

Key Features:

  • Bass preamp and overdrive pedal with a full, aggressive sound
  • Split signal into 2 variable filters for tone shaping
  • Lowpass-filtered signal remains clean for maximum punch and fundamental impact
  • Highpass-filtered signal goes to the drive circuit for adding harmonic saturation
  • Level controls for high and low filters allow you to create your ideal sonic combination
  • 4-band graphic EQ with high- and low-shelving bands, 500Hz band, 1kHz band, and master level control
  • Direct output and parallel output for flexible routing options
  • Suitable for stage and studio use

Darkglass Microtubes X7 Bass Distortion Pedal Review | The Music Zoo

themusiczoo.com

The Darkglass Microtubes X7 is a versatile powerhouse, delivering articulate high gain, punchy overdrive, and raw fuzz, making it a must-have for bassists seeking tonal control. Its 6-band EQ and dual outputs add to its appeal, allowing players to shape their sound with precision. However, some might find the slightly scooped-mids tone less favorable, and the price tag of $299.99 could be a hurdle for budget-conscious musicians. Overall, the X7 shines in its ability to adapt to various soundscapes while still maintaining a balanced bass tone.

Most useful bass drive I've ever played.

Having already owned a Darkglass OD, I took the plunge with this after finding it for almost half off on a clearance sale on a website going out of business, and man do I not regret it. Apart from having just a completely fantastic drive, it does the job it promises to do, to effectively give you studio quality sound by splitting your signal into clean compressed lows, and distorted highs. The graphic EQ and high and low pass filters are just cherries on top of the whole thing. You can do about any type of drive with this, without ever sacrificing low end.

EQing Distortion

An innovative distortion pedal. It's essentially a way to EQ Distortion. It's nice being able to get down and really fine tune your distortion to the sound you need. With the low and high-passes being able to go between grit, fuzz, or just some light distortion to highlight the punch the beef of the notes. Versatility is key for me and this pedal gives it.

For years, Nolly has used the Darkglass B7K Ultra and B7K Ultra V2, however, more recently with the release of the new Darkglass Microtubes X and X7, Nolly has adapted these new types of distortion. Nolly can be seen with the X7 on his home studio desk while tracking the bass for Periphery 4, first recording a DI from his bass, then continuing to 're-amp' the bass through then X7.

Nolly talks about how he has had a consistant method of building his bass tone, yet he has achieved it in different ways. In the past Nolly has used the B7K and FabFilter Saturn to create his distortion tones, for Periphery 4, we'll hear the X7 - likely for the majority of the album.
