In the world of professional recording, the EQP-1A is what you’ll want to hear. One of the most revered equalizers of all time, the all-tube EQP-1A is beloved by recording and mastering engineers for its almost magical ability to virtually Can improve the sound of any signal.

    RCKODLE The result of extensive research and development, the RCK-18 captures the essence of the EQP-1A, retaining the original EQ section design, control layout and beautifully smooth musicality. While restoring the original version, the transistor CLASS A amplification module makes the sound cleaner. No need to worry about the aging of electronic tubes.

    The RCK-18 has the same frequency settings and inductor, making it a product that accurately captures and shapes the sound spectrum, especially the bottom end. The high frequency band is attenuated at 4K, 8K, 12K, 16, and 20KHz; the bandwidth and boost can be changed at the mid-to-high frequency bands of 1K, 1.5K, 2K, 3K, 4K, 5K, 8K, 10K, 12K, 14K, and 16KHz; of course low Frequency bands can be boosted or attenuated at 20Hz, 30Hz, 60Hz, 100Hz, and 150Hz.
