The LR Baggs Align Series Session acoustic pedal brings a signature studio sound to your live rig. Session circuitry enhances your acoustic pickup and imparts the rich sonic character that you'd expect from an experienced audio engineer using some of the world's finest studio gear.Often used by studio engineers in post-production, saturation adds warmth, dimension, and pleasing harmonics while smoothing the signal for an enhanced mix. The Session’s proprietary saturation is voiced specifically for the acoustic guitar and transports studio analog warmth and inspiring playability to the stage.Unlike standard compression that can squash the entire range of your signal, the Session’s Comp EQ features 3 narrowly focused bands of compression that tame common problematic frequencies and uncover the voice of your guitar. The low, mid, and high frequency compressors are essentially “touch-sensitive” EQs that respond in real-time to your dynamics. The harder you strum, the more they compress and vice versa.LR Baggs Align Series Session Features:Analog Saturation enhances warmth and harmonic contentCompression / EQ smoothes out common problem frequenciesAdjustable gain for both passive and active pickups LR Baggs ALIGN-SESSION Saturation and Compression EQ Pedal for Acoustic Instruments.
