This all-analog, two-channel preamp pedal is designed to accentuate distorted bass tones. The clean channel, powered by a CMOS circuit, warms up your tone with subtle compression and tube-like response. The Subatomic Drive channel delivers ferocious bass tones that can be blended with clean tones to create aggressive distortion. Each channel shares a 3-band passive EQ, allowing for a wide range of tones. It also features an FX loop and cabinet simulation for convenient post-drive effects, and an XLR DI output eliminates the need for an external DI box. It's a highly effective tool for bassists looking for a clear, heavy distorted bass tone while retaining a natural low frequency range. ■Sub Atomic The Sub Atomic preamp is a fully analog two-channel preamp designed for the most punchy bass tones, featuring cascaded CMOS stages with parallel processing for natural low frequencies. It's an effective tool for reproducing distorted bass tones with clarity and rich response. ■2-channel preamp The clean channel adds warmth to the tone with the delicate compression and tube-like response unique to the CMOS stage, while the subatomic drive channel produces a sound that blends clean tone with very aggressive distortion. Both channels share a common 3-band passive EQ, allowing you to extract the maximum tonal range from this versatile device. ■XLR & Cabinet Simulator The XLR DI output includes a huge 8x10 analog cabinet simulation that can be turned on/off. It also has an effects loop, so you don't need an external DI box when using post-drive effects.[Main features] ■ 2-channel preamp "Clean" and "Subatomic" Clean channel (gain and tone adjustable) Subatomic channel (gain, voicing switch, sub blend, sub low-pass filter switch (off, 100Hz, 500Hz), level adjustable) ■ 3-band EQ (80Hz, 500Hz, 2kHz) ■Top-notch analog 8x10 cabinet simulation■Equipped with a pre-output effects loop■Optional analog cabinet simulator with XLR balanced output■Bypass soft footswitch■Channel soft footswitchThe pre-effects loop can be assigned to the preamp, parallel chain, or both simultaneously.You can use different effects on the left and right without using splitters or additional cables. ■XLR output: There are two systems, "Main" and "Parallel," which can be assigned to different devices or channels and used for re-amping and recording, or they can be used to output a subwoofer separately. ■Headphone output with auxiliary input and two TS outputs with parallel through and main cabinet simulator bypass options.
