Sound Pure's Take
Condition: Used, Excellent
Experience pristine, studio-quality sound reinforcement with the L.R. Baggs Reference Acoustic Amplifier! Designed specifically for discerning acoustic musicians, this high-grade amplifier features an ultra-high 10-megohm 1/4" input alongside a balanced XLR input, ensuring both high-impedance piezos and studio microphones sound natural, detailed, and uncolored. Deep tone-shaping is made simple with a semi-parametric 4-band EQ and a sweepable notch filter designed to eliminate problematic feedback frequencies on live stages. Pushing up to 108 dB SPL and loaded with direct, line, and FX loop routing options, this 28 lb portable rig offers unbeatable dynamic headroom and tour-ready durability for acoustic soloists and multi-instrumentalists alike.
