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 PastFx Preamp Crunch Plus is a preamp pedal from the boutique maker, aiming to reproduce amp-style crunch and gain staging rather than a single fixed drive voicing. PastFx builds vintage-inspired analogue effects in small runs with little independent press coverage, so its exact circuit lineage is not established here; those interested should reach out to PastFx directly for specifics.

The Source Audio L.A. Lady is a programmable DSP overdrive carrying three onboard drive engines. Classic delivers the sound of an overdriven Marshall, mid-forward with a British crunch character; Smooth gives a saturation modelled on a Mesa/Boogie with boosted highs and lows for a beefy, precise, long-sustaining lead voice; and Crunch is Source Audio's own warm, chunky low-gain design. Each of the three slots can be reloaded from over 40 additional overdrive, distortion and fuzz algorithms through the free Neuro mobile and desktop editors, with custom presets saved and shared. MIDI expands storage to 128 presets with program change support. It pairs DSP flexibility with an organic, amp-like feel rather than an obviously digital one.
