The Subatomic preamp is an all-analogue 2-channel preamp designed to bring the most brutal bass tones. Cascading CMOS stages with parallel processing for natural low frequencies makes it an effective tool for playing distorted bass tones with definition and full-bodied response.

Key Features

  • Versatile Tones – 2-channel preamp “clean” and “Sub Atomic”.
  • Cab Sim – The Sub Atomic features an optional analogue 8×10 Cab Sim with effects loop to ensure shaping your ultimate bass tone is always at hand.
  • No Menu Diving – Change settings on the fly with full control, and no menus for ease of use!

2 Channels

The clean channel brings the subtle compression and tube-like response of CMOS stages to warm up your tone, and the Subatomic drive channel has a very aggressive distortion with a clean blend. Both channels share the 3-band passive EQ to get the most ample range of tones out of this versatile device.

XLR & Cab Sim

But that’s not all. We included an XLR DI out with switchable analogue cabinet simulation of a huge 8×10 fridge and an FX loop, so you won’t need an external DI box when using post-drive effects.

Preamp & DI Pedals

A preamp brings an instrument signal to a controlled level and shapes its impedance, gain and frequency balance before amplification or recording. A DI converts the signal for a balanced, low-impedance connection and may include ground lift, pad and transformer isolation. Combined units can add drive, cabinet filtering, effects loops and parallel outputs while keeping the direct path stable.

Tags

Analogue

The signal is shaped by continuously varying electronic circuitry rather than being converted into a digital effect algorithm. Component choice, operating voltage and circuit tolerances influence headroom, noise, clipping texture and the small variations in response between designs.

Bass

Voiced or equipped to retain low-frequency fundamentals and the higher headroom of a bass signal. Clean blends, crossovers and bass-specific filter ranges can preserve weight and articulation while the effected portion adds harmonics, movement or ambience.

Cab Simulator

Recreates the strong frequency filtering and resonance imposed by a loudspeaker cabinet and its microphone. It removes the harsh, extended high end of an unfiltered preamp signal and may offer cabinet size, speaker, microphone, position and room choices.
