Bass 3500 Amplifier

"The unmistakable punch, definition, and flexibility of a legendary hybrid bass amplifier"

Modeled after the legendary Hartke HA3500* bass amplifier

Nembrini Audio Bass 3500 captures the powerful low end, fast transient response, and distinctive hybrid preamplifier design of the original amplifier.

Key Features

- Hybrid Preamp: Independently blend Tube and Solid State stages to combine harmonic warmth, clarity, definition, and punch.

- Built-In Compressor: Controls peaks, evens out dynamics, and adds weight and consistency to the bass signal. The activity LED provides visual feedback for compression and limiting.

- Ten-Band Graphic Equalizer: Provides ±15 dB adjustment at 30 Hz, 64 Hz, 125 Hz, 250 Hz, 500 Hz, 1 kHz, 2 kHz, 3 kHz, 5 kHz, and 8 kHz.

- Contour Controls: Broad Low Pass and High Pass controls shape the low-frequency region around 100 Hz and the upper-frequency region around 10 kHz.

- Pre-Amplifier Stomp Effects: Noise Gate, Envelope Filter, Octaver, and Modern Tubes Drive. Every pedal is draggable and reorderable for complete signal-chain customization.

- Cabinet and Recording Chain: Four bass cabinet emulations, four microphone models, adjustable microphone positioning, tweeter controls, parallel D.I. processing, and three ambience environments.

- Dual Impulse Loader: Load and blend up to two third-party impulse responses with level, pan, phase, Solo, and Mute controls.

- Six-Band Parametric Equalizer: Detailed post-amplifier tone shaping with multiple filter types, adjustable frequency, gain, and Q.

- Post-Amplifier Effects: Studio Compressor, bass-optimized Modulation, and Analog Delay. Every effect is draggable for flexible routing.

- Cabinet Bypass: Bypasses the complete cabinet, recording chain, and impulse-loader section for use with external cabinet processors, IR loaders, or a real power amplifier and bass speaker system.
