## Features

- IMPORTANT – THIS IS AN AMP HEAD, NOT A COMBO AMP: The BADASS is a bass amplifier head only. It requires an external speaker cabinet (4Ω or higher, sold separately) to produce sound. Perfect for beginners, hobbyists, and gigging bass players. For silent practice, use headphone output with built-in cab simulation— speaker cab is automatically muted. Please ensure you have a compatible bass cab before purchasing.
- WARM 12AX7 TUBE PREAMP TONE: Powered by a genuine 12AX7 preamp tube, BADASS delivers warm, punchy bass tone with rich harmonics. 50W RMS output at 4Ω (25W at 8Ω) drives a wide range of bass cabinets (1×8, 2×10, 4×10, etc.). Suitable for rock, blues, pop, funk, and modern bass playing with the distinct character of a tube-driven amp. Tip: For full 50W power, use a 4Ω cabinet.
- BUILT-IN STUDIO TOOLS – COMPRESSOR, 3-BAND EQ & FX LOOP: Shape sound with a versatile 3-band EQ (Low, Mid, High) and an onboard compressor that can be engaged/disengaged via the included footswitch. The dedicated FX LOOP (Send/Return) allows seamless integration of modulation, delay, reverb, and other effects pedals.
- BLUETOOTH STREAMING & SILENT PRACTICE: Wirelessly stream backing tracks, songs, or practice material via Bluetooth. The headphone output features immersive, high-quality silent practice — perfect for apartment living, late-night sessions, and personal monitoring without disturbing others.
- PORTABLE, STAGE-READY & BUILT TO LAST: Compact and lightweight (1.32kg / 2.9lbs) with dimensions 163×110×140mm. Solid metal construction, built for the road. Includes footswitch, power adapter, and audio cable.
