BIG AL is a dual-stage tube saturator that delivers a rich range of harmonic textures through an interactive network within its transformer-coupled preamp and power amp. Crafted using authentic vintage components from the 1930s, this plugin is based on unique analog hardware designed exclusively for digital use. Its innovative circuitry captures the warmth and depth of classic tube saturation, offering a bold and musical sound character that enhances any audio source.

The plugin features precise frequency shaping starting in the EF9 preamp stage, where a Baxandall filter allows control over saturation intensity around 100Hz, with the option to simultaneously boost or cut bass frequencies. An additional high-frequency EQ band positioned before the preamp tube targets the 10kHz range, enabling users to either accentuate or soften the treble presence. These controls provide dynamic tonal shaping, essential for managing the plugin's distinctive harmonic aggression.

BIG AL also incorporates a jumper matrix that unlocks advanced modifications to its core circuitry, including Emphasis Shift, Bass Compensator, and Voltage Sag. These features enable complex adjustments to the distortion profile by simply engaging or disengaging specific connections. The power pentode stage, driven hard by the preamp, completes the signal chain with a warm, organic output transformer saturation, resulting in a lush harmonic texture that remains musical and natural across various audio applications.
