{"product_id":"gr-bass-one-350-blk-350359","title":"One 350 BLK","description":"\u003ch3\u003eHistorical Context and Positioning in the Range\u003c\/h3\u003e\u003cp\u003eThis amp head fits into the modern approach to bass amps: \u003cstrong\u003elots of power in a lightweight chassis\u003c\/strong\u003e, with features expected on stage (DI, Mute, headphone monitoring) and practical daily tools (VU meter, built-in tuner, 9V power supply for pedals). It aims for a clear compromise: \u003cstrong\u003eease of use\u003c\/strong\u003e and \u003cstrong\u003eversatility\u003c\/strong\u003e without the bulk of a rack or heavy combo.\u003c\/p\u003e\u003ch3\u003eWho This Amp Is For\u003c\/h3\u003e\u003cp\u003eThis head is suitable for the \u003cstrong\u003ebeginner to advanced bassist\u003c\/strong\u003e who wants a reliable amp, easy to dial in and powerful enough to \u003cstrong\u003erehearse with a drummer\u003c\/strong\u003e and handle \u003cstrong\u003esmall to medium gigs\u003c\/strong\u003e (notably via the DI to the PA). In the home studio, the 3.5mm headphone output with level control and the fan in Studio mode facilitate quiet work. Regarding styles, its 4-band EQ and Deep\/Bright voicings make it comfortable from \u003cstrong\u003efunk\u003c\/strong\u003e to \u003cstrong\u003erock\u003c\/strong\u003e, including \u003cstrong\u003epop\u003c\/strong\u003e, \u003cstrong\u003emetal\u003c\/strong\u003e (sharper attack), and rounder genres like \u003cstrong\u003ereggae\u003c\/strong\u003e.\u003c\/p\u003e\u003ch3\u003eFeatures and Innovations\u003c\/h3\u003e\u003cp\u003eThe heart of the machine relies on a very straightforward control chain: \u003cstrong\u003eadjustable Gain\u003c\/strong\u003e to set the input level, then \u003cstrong\u003eMaster Volume\u003c\/strong\u003e to manage the overall volume. The \u003cstrong\u003e4-band EQ\u003c\/strong\u003e can be activated or bypassed (EQ on\/off) to instantly switch from a shaped sound to a rawer tone. Two dedicated switches (Medium and bypass) allow quick curve changes, useful for switching from fingerstyle to pick playing, or from a verse to a denser chorus.\u003c\/p\u003e\u003cp\u003eTo refine the character, the \u003cstrong\u003eDeep\/Bright\u003c\/strong\u003e switch offers two musical directions: more depth and low-end foundation, or more brightness and definition to highlight the attack. The \u003cstrong\u003eMute\u003c\/strong\u003e is ideal for changing instruments, tuning silently, or cutting the signal between songs. The monitoring section includes a \u003cstrong\u003e3.5mm headphone output\u003c\/strong\u003e with \u003cstrong\u003elevel control\u003c\/strong\u003e and a \u003cstrong\u003e3.5mm Aux input\u003c\/strong\u003e for playing along with tracks, a metronome, or backing tracks.\u003c\/p\u003e\u003cp\u003eFor stage\/studio integration, the head features an \u003cstrong\u003eexternal effects loop\u003c\/strong\u003e (handy for chorus, delay, multi-effects, or additional preamps), and especially a \u003cstrong\u003eDI output\u003c\/strong\u003e with \u003cstrong\u003ePre\/Post switch\u003c\/strong\u003e to send either a signal before or after EQ. A \u003cstrong\u003eGround Lift switch\u003c\/strong\u003e helps reduce hum caused by ground loops. Finally, the \u003cstrong\u003e9V DC output\u003c\/strong\u003e powers up to 4-5 effects pedals: an excellent solution for a minimalist pedalboard when traveling light for gigs.\u003c\/p\u003e\u003ch3\u003eThe Sound\u003c\/h3\u003e\u003cp\u003eDesigned as a \u003cstrong\u003etransistor-based bass head\u003c\/strong\u003e, it prioritizes \u003cstrong\u003eresponsiveness\u003c\/strong\u003e and \u003cstrong\u003eclarity\u003c\/strong\u003e : tight lows, clear attack, and a rendering that respects the character of the bass (single-coil, humbucker, active). With the EQ off, you get a natural and quick foundation, ideal for laying down a clean sound and letting the playing speak. Activating the 4-band EQ allows precise sculpting: scooping for a more modern slap, thickening the low-mids for dense rock, or opening the high end to cut through a busy mix.\u003c\/p\u003e\u003cp\u003eThe \u003cstrong\u003eDeep\u003c\/strong\u003e and \u003cstrong\u003eBright\u003c\/strong\u003e voicings provide two effective shortcuts: Deep enhances the foundation and sense of depth (very musical with generous cabinets), while Bright emphasizes definition and articulation (useful for pick playing, harmonics, or regaining presence on stage). The clip LED and VU meter help set the Gain to keep a clean sound with enough headroom and avoid unwanted input saturation.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical
