The Hartke Systems Model 3500 Bass Amplifiers offers all the newest concepts in bass amplification.

Features
Power to spare - a full 350 watts into 4 ohms.

Hartke's unique Transient Attack¬ circuitry ensures that every nuance of your bass performance is reproduced faithfully.

Two Pre-Amp input knobs, allowing custom blending of tube and solid state sounds.

Ten bands of high-quality graphic equalization, allowing you to create a broad range of tonal colors for your bass instrument. A dedicated in/out button allows you to preset an equalization curve.

Two fully adjustable contour knobs (high pass and low pass) provide further control over shaping your bass sound.

A built-in compressor not only adds real "punch" to your bass sound, but also allows you to smooth out volume differences between notes.

Two independent inputs accommodate both passive and active bass guitars.

Protection relay circuitry protects connected speakers from dangerous overloading, and prevents "thumps" when powering on or off.

Effect loop send and return jacks allow you to connect to professional outboard effects processors.

An effect Balance knob enables you to adjust the relative amount of Send ("dry") versus Return ("wet") effect signal being routed to the speaker outputs.

An electronically balanced direct output provides a means of routing signal to professional mixing consoles in both live performance and recording environments. A ground loop switch helps prevent hum or buzz from entering… read more the signal, and a pre/post switch allows the direct signal to be derived either before or after the amp EQ section.

LEDs show you the settings of the graphic equalizer in low-light environments, as well as a 2-color LED that continuously shows the status of the compression circuitry in response to your playing.

Rugged construction makes the Model 3500 eminently roadworthy. read less
