## Description

Product description Ultra Series Microtubes X Ultra The Microtubes X Ultra greatly expands on the already immense versatility of the Microtubes X7. Featuring all the great controls that its predecessor has that allows users to select exactly what frequencies they want to compress and saturate for the low and treble respectively, but with four major additions providing an additional layer of flexibility, while maintaining the same compact footprint, making it an extremely complete tool for the modern bassist. Now Featuring... 6-band Graphic EQ: Low Shelf, 250Hz, 500Hz, 1.5kHz, 3kHz and High-Shelf Switchable Impulse Response Cabinet Simulation Auxiliary Input: connect your PC or phone to play along with your favorite songs or backing tracks Clean channel: bypass the distortion and low pass filter for a crystal clean tone Parallel processing split by two variable low-pass and high-pass filters at the input Technical Specifications

Review: The best pedal I've ever used. - Not only the best pedal I've ever used, but even a better tube driven tone than all my mesa and ampeg heads previously used. The parallel signal chain makes the deal. Being parallel allows you to add the distortion to only selected frequencies above your setting, which starts as low as 100hz, which is almost the entire signal. You can dial it up to 1Khz, meaning you're adding distortion to only the 1Khz band and above. This allows you to maintain a tight clean low end, with a grindy high end. Most people would use a guitar amp with a bass amp to get this sort of tone live, and on recordings they record two separate tracks, one clean and one distorted, but this pedal does it alone.
Review: How Heavy Metal Bass SHOULD be. - THIS is how heavy metal bass is supposed to sound. Literally don’t need anything else whatsoever. 🤤

### ⭐⭐⭐⭐⭐ Darkglass=Superior products
*by J***N on July 22, 2021*

This pedal is amazing, there's so many variations of tones and it cuts through everything in the mix. I've owned a bit of everything the lady 37 years and already own the Alpha Omega 900 amp. Do yourself a favor and grab one of these bad boys. After a week of researching I ordered it with confidence and am very happy. The boys from Finland know what they're doing.
