Similarity
citedBlended 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.

Description

The Benson Amps 424 MKII is a preamp and distortion pedal designed to recreate the saturation and harmonic character of the input stage of the Tascam Portastudio 424 MkII cassette four-track recorder. The circuit captures the non-linear behavior of cassette-era input electronics, spanning from subtle coloration and clean boost through compressed broadband distortion and unstable breakup. A switchable front-end buffer fundamentally alters the gain structure: engaged, it presents a high-impedance guitar input with tighter low end and increased headroom; bypassed, the circuit returns to a darker, fuzzier low-impedance cassette response. Four controls -- gain, trim, bass, treble -- cover a wide EQ range. Internal 18V operation provides increased headroom. Made by Benson Amps in Portland, Oregon.

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.
