Product Info
* Prices may vary. Check retailer for current pricing and availability.
The GR Bass ONE350 is a seriously powerful little head, built with Italian precision. It's a great choice for gigging bassists needing a lightweight, affordable amp with a modern, punchy sound. It's not going to replace a vintage tube amp, but it delivers a lot of bang for your buck in a small package.

Frequently Asked Questions
The DI output is pre/post switchable, offering flexibility for recording direct or miking the amp. Expect a clean, usable signal, although it might benefit from some additional EQ during mixing.
It bypasses the EQ, but solid-state amps inherently color the sound. Expect a cleaner signal, but don’t anticipate a completely neutral, ‘flat’ response.
It offers a more refined EQ section than many competitors, and the Italian build quality suggests a higher level of durability, justifying the slightly premium price point.
