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 Free The Tone PA-1QA is a programmable analog 10-band EQ specifically tuned for acoustic guitar, with frequency bands at 31, 62, 125, 250, 500 Hz, 1, 2, 4, 8, and 16 kHz, each offering ±12dB of boost or cut. It uses a hybrid architecture: fully analog signal processing paired with a digital control section that can precisely store and recall EQ presets and process parameters digitally, including real-time control via MIDI, while keeping the actual audio path analog.
The Source Audio Spectrum Intelligent Filter is a stereo filter pedal built around three distinct modes -- Tron, Dumpling and Thrust -- covering classic auto-wah quack, enveloped phaser sweeps, and distorted synth-like octave voices with raunchy saturation. Its strength is the relationship between input envelope and filter response, which reviewers describe as unusually natural and fluid where envelope filters are typically fiddly to set up, tracking pick attack closely and reacting musically at both soft and hard dynamics. It is completely free of the hiss and hum common to analogue envelope filters. Six factory patches ship onboard, with the Neuro desktop and mobile editors opening deeper sound design, alongside MIDI control. Works equally well on guitar and bass.
