Product Overview

The World’s most advanced digital loadbox.
The next generation of the world-acclaimed VB-101, this is the pinnacle of speaker and miking simulation – the ultimate loadbox! Its new features notably include a new loadbox with increased admissible power, a switchable impedance (4, 8, or 16 Ohms), and the possibility to choose between resistive and reactive loadbox. Its new, enhanced design makes it a more advanced, much lighter successor to.

The concept:
You may love the sound of your amplifier but playing it can come with certain problems (noise, weight…). We bring you the simplest way to get the best tone out of YOUR gear. The Torpedo Studio features a unique switchable reactive pr resistive impedance loadbox with 2 processing channels to get the best out of your amp.

Two Notes Studio
Exclusive Studio Technology
Highly realistic speaker simulation is achieved by use of convolution. Two Notes started from that technology and brought it much further, to accurately reproduce the characteristics of the whole miking chain (speaker, microphone, preamplifier, studio room acoustic).

Many parameters influence the sound of your guitar or bass rig when it comes to recording. Taking good care of the cabinet selection and miking will dramatically improve the sound of your takes. The Torpedo simulation reproduces the tiniest variations of a cabinet behavior such as frequency response and distortion (*). Move the microphone in the virtual studio room thanks to the Torpedo IR synthesis, control the phase with the Variphi: all the settings you need to achieve great recordings are here.

Dual mono/stereo miking: combined simulation of 2 cabinets + 2 microphones for optimal mixing. Position two different microphones before your speaker, or before two different speakers. Mix the two simulations to send them to the stereo outputs.

Post-FX section: when recoding guitars and basses it is common to apply a few effects to shape the sound before it is sent to the PA or recorder. The Studio comes with a simple but efficient EQ filter, 1-band exciter, and a studio compressor.

Power amp emulation: Plug your preamp directly into your Torpedo Studio. It embeds our component-based tube power amp simulation. Simply choose the amp design and characteristics, and select the tube type.

Control your Torpedo & access the Two Notes Boutique
With its clear and intuitive interface, Torpedo Remote will give you access to all parameters on your Torpedo, including loading and saving presets, loading new IRs, and updating the unit’s firmware. You can pick any speaker cabinets from the Two Notes Boutique, preview them on your own tracks in real time, and choose to buy the ones you prefer.

Studio-quality electronic design
The best simulation is nothing without a perfectly designed analog and digital circuit. Two Notes focuses on the whole signal chain, from your amp or preamp output to the PA, monitor, headphones or recorder to ensure the best performance. Guitar and bass players deserve studio quality gear ! Compared to its predecessor, the Studio achieves better signal to noise ratio, lower distortion, lower crosstalk, to preserve the full dynamics of your playing.

In the studio, it can be very interesting to record a raw track that you can later reprocess (we call this “remiking”) at the mixing stage thanks to the Torpedo Studio. This allows you to concentrate on the music when recording, not on the sound

Of course, you can record both processed and unprocessed signals to your DAW at the same time.
