GR Bass One 1400 1400-Watt 4-Ohm Bass Guitar Amp Head New

Lightweight, portable but powerful, the GR ONE series will surprise you with its quality and incredible power. The ONE series takes up and perfects the philosophy of PURE SOUND, a fundamental characteristic of GR products. A 4-band equalizer will allow you to sculpt the sound according to your needs but that’s not all: you can choose 6 frequencies for the mids, and the deep and bright filters will allow you to add punch and / or definition to the equalization.

Through the “PURE” switch you can exclude filters and equalizer and have a completely flat sound to be combined if necessary with an external equalizer, a very useful function when using different instruments in a concert. The 24-LED V Meter in 6 different modes (can also be excluded if necessary) also associates an extremely precise tuner mode, always active in “Mute” mode or activated during normal use, choosing it from the six available LED modes. The Aux-In allows you to connect an external sound source (Tablet, Smartphone) and the headphone output with separate volume control, it also allows an independent monitoring system. The D.I. of the GR ONE, recognized as one of the best, is perfect for use in professional contexts both live and in the studio. In the GR ONE 1400 we have two power amps of 700 watts each with independent volume!
