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 Alexander Pedals Marshmallow is a dual modulated pitch-shifter in the NEO Series with six processing modes and a CLOCK knob reducing internal sample rate from 44.1kHz down to 1.6kHz for deliberate lo-fi artifacts. Six modes: MOD (two pitch voices with LFO modulation for chorus-like texture), ARPY (pitch arpeggiator with rhythmic step sequences), RAND (random pitch modulation for unpredictable sounds), RING (dual pitch shift with auto-panning), DYNA (dynamics-sensitive pitch switching between two intervals based on pick attack), and CLOUD (dual pitch shift with feedback for reverb-like washes). Features 4 onboard presets, MIDI, expression pedal, and Neo Morph for seamless preset transitions.

The Hungry Robot El Castillo is an arpeggiating reverb pedal from US boutique manufacturer Hungry Robot (Plano, Texas), combining reverb with pitch-arpeggiated harmonic overtones that create melodic, arpeggio-like reverb tails. The El Castillo produces unique, evolving harmonic reverb textures through pitch arpeggiation within the reverb tail. Hungry Robot Texas boutique construction.
