Described as similar to a Soldano SLO with a Marshall high mid bite; covers more sonic spectrum than a Diezel, which is more compressed with low mid focus.

Diezel amps, like the Herbert and Hagen, have a unique roar and handle down-tuned guitars better than the Mzero.

Offers a thick and liquid gain sound reminiscent of the Soldano SLO, but with additional aggressive options thanks to its unique features.

The Mzero OD without a boost pedal may not tighten low-end for down-tuned guitars, unlike the Skill 30, which handles baritone guitars better.

Owners find the Mzero "addicting to play" and assert that profiles can't capture its full sound, unlike with some other amps.

The clean channel is unexpectedly high-quality, providing a pleasant surprise in terms of feel and tonal clarity, making it more versatile than anticipated.

The Mzero is favored over Soldano for its feel under the fingers, offering more sag and gain, though Soldano is noted for versatility with its effects loop volume and dual master volumes.

Purchased new at a deal, but still a significant investment; not full retail price but impactful on the wallet.

Brilliant for a wide sonic range, offering a 3D sound, making it versatile for various styles beyond just low tunings.

The Mzero excels with a little delay, making it suitable for blending atmospheric sounds with heavy distortion.

The negative feedback dial allows for a more aggressive sound compared to a Soldano SLO, enhancing the amp's versatility in tone shaping.

The negative feedback knob adjusts the amp's openness, transitioning from Diezel-like tones to more open Soldano or Plexi-like tones.

The Skill 30 can be modded to include a negative feedback control, increasing its tonal versatility.
