GRBass CUBE350

The GRBass Cube 350 is a lightweight and compact bass amplifier with a 12-inch speaker. It’s ideal for taking on the go and for smaller gigs. This amplifier delivers plenty of punch without sacrificing low-end response.

Thanks to the switchable HF tweeter, you can fine-tune the amount of high end. You can keep your bass tone clean using the handy VU meter and the gain knob. For an even better sound, there’s a built-in tuner so you can fine-tune your instrument. There’s also a mute button to turn off the speaker.

You can use the EQ to customize your sound to your liking. The midrange is divided into mid-low and mid-high, each with 3 frequencies. But that’s not all—to get even more clarity or bass, switch on the “Bright” or “Deep” modes. If you prefer to play without equalization, the “Pure” button is a great option.
