Undertone Audio GB Tracker II Combination Instrument Preamp And Re-amplifying Device

The Undertone Audio GB Tracker II is a powerful combination instrument preamp and re-amping device designed to slot seamlessly into modern hybrid studios. Acting as a pristine front end for guitars and basses while also providing a guilt free re-amping path, it lets you capture inspired performances once and then experiment with amps, pedals and tones for as long as you like without asking the player to redo a single take.

At the heart of the GB Tracker II is a custom transformer that presents your amplifier with the same impedance and feel as a real guitar or bass. When paired with Undertone Audio’s Satellite Re-Amp, you can expand into a multi-amp re-amping rig with perfectly matched gain steps and repeatable recall. Whether you are tracking at home or in a commercial room, the GB Tracker II gives you a consistent, musical way to move between clean DI, coloured analogue front end and fully cranked amps.

Engineers and producers who live in the box but love real amps will appreciate how the GB Tracker II streamlines the entire workflow. Record a clean DI through the instrument preamp, commit a rough amp sound for vibe if you like, then come back later and send that same performance back out to one or more amps for serious tone shaping. With gain staging designed to integrate directly with the Satellite Re-Amp, it is easy to maintain level, headroom and feel at every stage of the chain.

Because it is purpose built for re-amping as well as tracking, the GB Tracker II helps you avoid the usual compromises. You no longer have to choose between committing to a sound too early or living with sterile DI tracks that never quite sit right. Instead, you get a musical, amp friendly signal path from the first note to the final mix, with the flexibility to rework tones at any time.

Revolutionary Tracking And Re-Amping Workflow

The GB Tracker II is designed from the ground up to make re-amping as natural as tracking. Capture your performance through the instrument preamp, then route that same DI back out to your amps whenever inspiration strikes. This encourages creative experimentation, letting you audition different amps, gain structures and pedal chains long after the player has left the studio.

Custom Amp-Friendly Transformer

Undertone Audio’s custom transformer is engineered to interact with your amplifier exactly like a guitar or bass would. Your amp sees the correct impedance and level, so it responds with the same dynamics, touch sensitivity and harmonic content you would expect when plugging straight in. This keeps your re-amped tones authentic, lively and responsive under the fingers.

Perfect Partner For The Satellite Re-Amp

Gain steps on the GB Tracker II are matched to the Satellite Re-Amp, making it simple to dial in consistent, repeatable levels between tracking and re-amping. When used together, they form a cohesive system that takes the guesswork out of level matching, helping you avoid unwanted noise, distortion or loss of punch as you move between DI and amp signals.

Expandable Multi-Amp Setups

If you want to explore complex amp blends, the GB Tracker II integrates with daisy-chained Satellite Re-Amps so you can feed multiple amplifiers from a single DI performance. Each amp can be driven optimally while maintaining phase coherence, giving you huge, layered guitar and bass sounds that still sit neatly in the mix.

• Combination Instrument Preamp And Re-Amping Hub - Serves as both a high quality front end for guitars and basses and the central routing point for sending recorded DI tracks back out to amplifiers, simplifying your entire tracking and re-amping workflow.
• Custom Transformer For Authentic Amp Interaction - The dedicated transformer is tuned so your amp behaves as if a guitar or bass is plugged straight in, preserving feel, dynamics and tone when re-amping.
• Gain Structure Matched To Satellite Re-Amp - Calibrated gain steps ensure smooth level matching with the Undertone Audio Satellite Re-Amp, helping you maintain headroom and clarity from the DAW to your amps.
• Expandable Multi-Amp Re-Amping - Easily integrate with daisy-chained Satellite Re-Amps to drive several amplifiers from one performance, opening up rich, layered sounds without complicating your signal flow.
