The AG-20 is a fingerpicked acoustic guitar library featuring a Richwood A-20 guitar, available as a VST plugin and compatible with Kontakt 5 and HISE. It offers a realistic playing experience with samples ranging from D1 to E4, capturing soft and hard dynamics for each note and interval. The library includes various articulations such as power chord slaps, release samples, harmonics, and a 12-string guitar simulation mode that extends the sonic palette up to the high E string.

This instrument incorporates a predictive playback feature that enhances realism by analyzing MIDI note intervals and playing corresponding real samples for major and minor thirds, fourths, and fifths. This intelligent scripting allows for natural chord voicings by combining interval samples with solo notes, making complex chords sound authentic and dynamically rich. Round robin sampling across articulations, including chord change noises and percussive sounds, adds further depth to the performance.

With over 497 samples and a compact footprint of 170 MB for the VST and 407 MB for Kontakt, the AG-20 is designed for efficient use without compromising quality. It requires a 64-bit system and the full version of Kontakt 5.8 or higher for Kontakt compatibility. The library provides a detailed and expressive acoustic guitar sound suitable for a wide range of musical styles, capturing the nuances of fingerpicking and offering creative options for producing lifelike guitar tracks.
