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. Shown only within a gear class, and only where there's enough evidence to be meaningful.30% — somewhat different

The Walrus Audio Iron Horse LM308 V3 is a high-gain distortion built on the LM308 op-amp at the heart of the ProCo RAT, delivering meaty, punchy, gnarly dirt that gets genuinely rowdy in front of an amp. It is not a straight RAT clone: the highs are rolled back and the bass more accentuated, giving a thicker, darker and slightly fuzzier voice with a smoother midrange, less presence and less flattening of the guitar's natural low-end bloom than the original. The V3's headline change is a continuous clipping dial that blends between different clipping diodes, reaching hybrid textures no single-diode circuit can produce, from tight and compressed to loose and open. It adds top-mounted jacks, a soft-relay true bypass switch and a fixed volume drop-off with the distortion knob at minimum.
The Wampler TCD (The Compulsion Drive) is Brian Wampler's reimagining of the Fulltone OCD distortion circuit, offering Gain, a 3-band EQ (Bass, Mids, Treble), and Level controls, plus a Mode switch selecting between a traditional gain structure and cascaded MOSFET gain stages for a harder-hitting, more tube-like sound. Hidden Fat and Diode switches add further tonal options: Fat adds deep low-end warmth, while Diode shifts the gain profile via an added clipping diode for tighter, more saturated distortion.
