The TC Electronic Ampworx JIMS 45 preamp pedal brings you back to the golden age of rock with its faithful recreation of a 1965-era JTM45 tube amplifier. With the power of advanced AMPWORX modeling technology, the JIMS 45 captures every nuance of the original circuitry for authentic vintage tone in a compact stompbox. The 2-channel preamp design provides independent gain controls and footswitchable boost, allowing you to switch between crystal-clean rhythm and searing lead tones with ease. Shape your sound further with familiar tone-sculpting controls like Presence and Master Volume. The optional cab sim and dedicated DI output make it easy to get studio-quality direct tones, while the 1/4" outputs let you run the JIMS 45 into your favorite amp or monitor. Whether you want to conjure up classic rock crunch or find inspiration for modern tones, the JIMS 45 preamp pedal brings legendary tube tone to your feet.

Advanced AMPWORX Modeling Captures Every Component of the Original Circuitry

At the heart of the JIMS 45 preamp pedal lies TC Electronic's acclaimed AMPWORX technology, which meticulously analyzes and recreates the sound of iconic guitar amps down to the last detail. Just like the original JTM45 it's based on, the JIMS 45 uses a 12AX7 preamp tube to shape your tone. From there, advanced modeling captures the complete signal chain including the tone stack, transformers, speakers and more. The result is warm, touch-responsive tube amp tone with all the richness and complexity of the original vintage JTM45 circuitry. Whether you want glassy cleans, sweet overdrive or face-melting distortion, the JIMS 45 delivers authentic vintage tone and dynamics.

Independent Channels With Pre/Post Boost Provide Versatile Tone Shaping

The JIMS 45 preamp gives you independent gain controls for the Normal and High inputs, allowing you to set up crystal-clean rhythm tones on one channel and then kick into overdriven lead tones on the other. Just like channel-switching on the original amp, it's easy to go from shimmering chords to wailing solos without messing with your settings. You can also boost your signal by up to 5dB before or after the preamp stage for even more tonal options. Engage the pre-boost for enhanced touch sensitivity and dynamic playing response. The post-boost pushes the preamp tubes harder, adding saturation and distortion. The footswitchable design makes it simple to turn the boost on and off for solos or choruses.

Optional Cab Sim and Direct XLR Output for Recording

Thanks to amp modeling technology, the JIMS 45 lets you get authentic tube tones direct to your interface or mixing board. Just enable the optional cab sim to shape your direct output with speaker modeling for a ready-to-mix guitar sound. The XLR DI output sends your signal directly to the PA or interface with cabinet emulation applied. You can also use the 1/4" outputs to run the JIMS 45 into your stage amp or monitors. Dedicated headphone and line level outputs with independent volume control provide even more flexibility for practice and recording.

Intuitive Controls Mirror the Original Amp

The control layout stays true to the original JTM45 amplifier, giving you a familiar look and feel right out of the box. Tweak the active 3-band EQ to shape your tone just like you would on the vintage amp. Adjust Presence and Master Volume to fine-tune your gain staging. External speaker jacks let you pair it with your favorite guitar cab. Whether you want to nail those vintage rock tones or forge new ground, the JIMS 45 preamp gives you the tools. Just plug in, tweak some knobs and let your inspiration run wild.
