Albuquerque's Flat line compressor vs Donner Lax Comp
The Albuquerque's Flat line compressor and the Donner Lax Comp are both pedals sharing sustaining, transparent. The Albuquerque's Flat line compressor leans compressed. The Donner Lax Comp leans smooth.

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.50% — moderately similar

Albuquerque's Flat Line Compressor is a boutique build of the John Hollis Flatline circuit, a well-known optical compressor design within the DIY guitar effects community using an LED-and-photoresistor combination, sometimes called a Vactrol, to control gain reduction. With the sustain control dialed back the circuit offers roughly three times gain between soft and hard playing dynamics, and fully engaged that ratio climbs to around twenty times, flattening output enough to produce long, even sustain while keeping the characteristically transparent, non-distorted compressed tone optical designs are known for. Hollis was an early and influential contributor to the DIY pedal scene, and his Flatline circuit has since been built and sold by multiple small boutique makers, of which this Albuquerque's version is one example.
The Donner Lax Comp is an optical compressor pedal from the Chinese budget effects manufacturer Donner, inspired by the smooth, transparent compression of vintage optical compressor designs such as the Teletronix LA-2A. Optical compressors use a light-dependent resistor for gentle, program-dependent compression with smooth attack and release behavior. The Lax Comp provides LA-style optical compression at budget pricing.
