The Microtubes B7K Ultra takes bass processing to new heights with its comprehensive cabinet simulation capabilities and professional connectivity options. This upgraded version builds upon the original's versatility whilst adding single user loadable cabinet simulation impulse responses, giving you complete control over your virtual cabinet sound.
Connect directly to your PC or Mac via the Micro-USB B port to load different Virtual Cabinets through the Darkglass Suite software. The pedal features both a 3.5mm headphone output with cabinet simulation for silent practice and a balanced XLR output with switchable cabinet simulation for professional recording and live applications.
The 3.5mm stereo Auxiliary Input lets you jam along with backing tracks from your smartphone or laptop, though this function works exclusively with the headphone output. Level control remains with your audio source rather than the pedal itself, so always start with low levels before connecting any device to the aux input to protect your hearing and equipment.
