Le Bass
Dual-channel tube bass preamp with 200V design, Fusion modes, DI/effects loop/MIDI—Wall of Sound III included.
Two Notes Audio Engineering operates from France specializing in cabinet simulation, load boxes, and tube preamp pedals since the late 2000s. The Le Bass delivers true high-voltage tube bass preamp running internally at 200 volts—maintaining authentic tube warmth and dynamic response impossible with standard 9-volt pedal circuits. Dual independent channels provide comprehensive tonal flexibility: Channel A features ultra-clean lower-gain tube stage with pre-gain EQ (Bass/Treble) using vintage design approach for lightning-fast response and modern techniques, Channel B offers higher gain with powerful post-EQ including Bass, sweepable Mid, and Treble for rock bass with solid punch and sweet breakup.
Fusion modes expand tonal possibilities beyond standard channel switching: Cold Fusion blends both channels in parallel mixing clean A with overdriven B, Hot Fusion cascades channels with A boosting B for focused distortion to synth-like growls. Balanced DI output with ground lift eliminates ground loop hum when connecting directly to PA systems or recording interfaces, headphone output enables silent practice, post-EQ effects loop allows inserting modulation or delay after preamp coloration, thru output sends unaffected signal to stage amplifier, MIDI in/out enables preset recall via MIDI controllers. Integrated cabinet simulation affects DI and headphone outputs, includes free download of Two Notes Wall of Sound III speaker simulation software with extensive cabinet library.
True bypass operation, dimensions and power specs not documented. The Le Bass targets bass players seeking professional tube preamp character with comprehensive routing options and DI capability, suitable for studio recording, live performance, and practice scenarios where authentic tube bass tones and flexible connectivity enhance workflow without requiring heavy tube amplifiers or compromising tonal authenticity.
