Fender Rumble 100 V3 12" 100W Bass Combo Amplifier

The Fender Rumble 100 V3 is a compact bass combo amplifier built for players who want a straightforward, portable rig with enough output for practice, rehearsal, recording, and smaller performance settings. Its 100-watt Class-D amplifier and single 12-inch Eminence Special Design speaker provide a focused bass platform without requiring a separate head and cabinet. It is designed for passive or active bass guitars through its front-panel instrument input.

This combo gives bassists a clean foundation that can be shaped for different playing styles. The four-band EQ provides Bass, Low-Mid, High-Mid, and Treble controls, while Bright, Contour, and Vintage voicing switches offer quick tonal changes. Contour reduces midrange while boosting selected low and high frequencies, and Vintage adds dynamic compression with a low-pass filter.

An onboard overdrive section adds harmonically rich preamp distortion when needed. Separate Drive and Level controls let players adjust the amount and volume of the overdriven sound relative to the clean signal. The amp also uses Fender Delta-Comp limiting, which increases compression and sustain as the master level is raised or the instrument is played more aggressively.

The Rumble 100 V3 supports practical rehearsal and recording connections. A rear auxiliary input accepts an external audio source, while the headphone output automatically mutes the internal speaker for private practice. Its balanced XLR line output can feed a PA system or recording console, with a ground-lift control to help address hum caused by grounding differences.

For players using pedals, the rear-panel effects loop places compatible external effects after the preamp section. A footswitch jack allows remote switching of the overdrive circuit with an optional single-button latching footswitch. This makes the Rumble 100 V3 a self-contained bass amp that can also work as part of a larger live or recording setup.

Design & Installation

The Rumble 100 V3 uses a lightweight plywood cabinet with black textured vinyl covering, a silver grille cloth, and a painted metal front panel. Its ported enclosure has a removable grille, while the molded plastic strap handle uses nickel-plated caps. The combo measures 16.5 inches wide, 18.5 inches high, and 14 inches deep, and weighs 22 pounds.

Place the amplifier on a stable surface with its controls accessible, then connect a bass guitar to the 1/4-inch input and use the included IEC power cord with a grounded AC outlet matching the rear-panel rating. Use the 1/4-inch send and return connections for compatible external effects, or connect the balanced XLR line output to a mixer, PA, or recording interface. For silent practice, connect headphones rated at 32 ohms minimum; the internal speaker is automatically muted when headphones are connected.
