Introducing "ULTRA," a multi-band distortion pedal with even more scalability and versatility than Darkglass's proud "X7"! Introducing the Microtubes X ULTRA, the latest gear from Darkglass Electronics. It retains the characteristic controls of the popular bass distortion Microtubes X7 (allowing you to select frequencies for compression and saturation on the low end and treble separately) and four key functions that expand its flexibility, while adding new functions in a compact package. The newly added clean signal compressor can be turned on via the dedicated Darkglas Suite application. It is a dedicated compressor for the clean signal when the distortion section is bypassed. When a mobile device is connected to the AUX INPUT, the playback source is output from the headphone jack, making it ideal for late-night practice sessions while following along with music.[New Features]・6-band active graphic EQ ・Digital cabinet emulator ・Clean signal compressor mode ・3.5mm headphone output ・AUX input ・Darkglass Suite (dedicated PC software) compatible [Control]・High-pass frequency: Sets the high-frequency range (cutoff frequency) to be distorted.
