Check the listing for details. Jackson Audio Bloom Compressor Pedal - Anodized Black. Condition: New. Listed at 263.20 USD. Comprehensive Dynamic and Tonal Control for Your Guitar Jackson Audio’s Bloom has become a contemporary pedalboard classic, empowering guitarists with studio-grade dynamic and tonal control in a stompbox format. Equipped with an optical compressor, Bloom enhances your sound by subtly reining in transients and dialing up the sustain, and it gives you the option of six different compressor modes to match your playing style. Bloom’s EQ section features a 3-band Baxandall-inspired EQ, with a midrange bell filter and high and low shelving filters that guitarists at Sweetwater found to remain musical no matter how far they took them. The third piece in the Bloom signal chain is the titular “Bloom” control, a clean boost with a hold function that gradually ramps up for dramatic sustaining effects.
