The ONE 800 delivers 800W RMS at 4 ohms, while the ONE 1400 uses two independent 700W power sections for a combined 1400W RMS at 4 ohms.\u003c\/p\u003e\n\n\u003cp\u003eBoth models suit bassists who need a compact amplifier head for live performance, rehearsal, touring, or studio monitoring without giving up flexible tone control. A four-band EQ, six selectable mid frequencies, Deep and Bright filters, Pure EQ bypass, integrated tuner, effects loop, DI output, auxiliary input, and headphone monitoring provide a versatile signal path for professional bass rigs.\u003c\/p\u003e\n\n\u003cp\u003eThe shared ONE platform includes a 24-LED VU meter with chromatic tuner functionality, selectable Studio and Live fan operation, an anti-bump XLR DI, and a 9V accessory power output. The 800W model uses a single master level, while the 1400W version provides independent master controls and speaker outputs for its two 700W amplifier channels.\u003c\/p\u003e\n\n\u003ch3\u003eKey
