t.c.electronic M-ONE XL

Knob operation, output, and performance are all without any particular issues.
It has 200 presets, all of which are easy to use and sound great. I believe it's a masterpiece.
Confirmed that user settings can also be saved.

There are scratches on the top surface, but overall I think it's in good condition.

Main unit, AC cable

Dual Engine Effect Processor

◆ Designed for musicians and live sound engineers who pursue quality, the M-One XL, in keeping with TC's tradition, offers the highest quality in its class.
◆ The XL Reverb technology, which can be considered the heart of the M-One XL, is the latest spatial simulation technology realized through TC's long-standing research and development in the field of reverb. The M-One XL reverb allows for precise adjustment of the reverberation components in all reverb algorithms. Furthermore, the range of reverb size settings has been expanded, allowing you to define anything from small spaces to extremely wide sound images independently of the decay time. In the M-One XL, the reverb size setting is reflected in both the early reflections and the diffused decay components, enabling extremely flexible settings such as wide spaces with short decay times or narrow rooms with long decay times.
◆ The M-One XL's reverb is composed of a combination of high-resolution early reflections and decay sounds, achieving a natural and clear sound that is unprecedented in this price range. M-One XL reverb technology allows for the setting of decay modulation. You can achieve dynamic decay sounds that go beyond mere simulation, from the extremely subtle modulations caused by air movement in real spaces to vintage-style modulations and even effect-like settings close to chorus or detune.
