Blended from circuit-archetype lineage, dynamic feel, tone-signal overlap and tone-vector distance — the tone vector itself is derived from editorial description text, not a measured acoustic signal, so this reflects how similarly the catalog copy describes the two, not a lab measurement.

The ProCo Fat Rat is an enhanced version of the classic ProCo Rat, adding switchable clipping between silicon (the classic Rat voice) and MOSFET/germanium options, with the MOSFET setting smoothing and subtly scooping the upper mids for a more amp-like, natural character. It delivers depth and character reminiscent of a nice tape machine, with a tone that can be both heavy and soft, crunchy without masking tube warmth or single-coil pickup character. Reviewers praise it as a killer-sounding pedal with a ton of distortion that still retains clarity, particularly excelling on heavy, down-tuned riffs where it outperforms a basic Rat 2. It suits players wanting the classic Rat foundation with real added tonal flexibility from silicon-to-MOSFET clipping options, spanning blues to metal.
The Warm Audio WarmBender is a selectable three-circuit Tone Bender style fuzz pedal, switching between a three-transistor NOS75 MkII circuit, a two-transistor NOS76 MkI-style circuit, and a modern silicon three-transistor circuit in one enclosure. A sag switch emulates the dying-battery sag effect vintage fuzz players chase for extra sputter and compression. Reviewers describe its character as chaotic, unpredictable, raucous, and wild, with the NOS76 setting delivering bright, edgy, cutting fuzz with sharp attack and the NOS75 setting delivering thunderous bass with smooth, woolly, fat fuzz tones. It suits players chasing authentic vintage germanium Tone Bender tones across multiple eras from one pedal rather than collecting several vintage-style fuzzes.
