Guitar Effects Pedal Radial TriMode (preamplifier)

The Radial TriMode is a tube-based distortion preamp that combines clean, rhythm channel, and high-gain tones in one compact pedal. Featuring a 12AX7 tube and extensive equalization capabilities, the TriMode allows you to create warm, harmonically rich distortion in the style of classic American amps.

The pedal has two overdrive channels: the first channel provides light overdrive with natural dynamics, and the second channel provides rich high-gain distortion for heavy riffs and expressive solos. The three-position midrange switch (+12 dB, +7 dB, 0 dB) allows you to flexibly change the sound character, adding aggression or softness to your mix.

The EQ section includes a two-band tone control as well as an anti-precession filter to reduce excessive high frequencies. The tone switch (+6 dB at 10 kHz, 0 dB, -6 dB at 1.8 kHz) helps you adapt the pedal to different amps and guitars.

The second channel also features a send/return effect loop that allows you to integrate external effects, such as reverb or delay, directly after the distortion. This results in a clear, spacious sound without unnecessary noise or compression.

Thanks to True Bypass, the TriMode doesn't color the signal, keeping the guitar's tone clean when it's turned off. The metal footswitches provide durability for live performances, and the LED indicators make it easy to monitor the active channel even in the darkness of the stage.

The pedal is powered by a 15V 400 mA adapter, which ensures stable operation of the 12AX7 tube and maximum signal quality.
