The Two Notes Captor X Pro Might Be the Best Load Box Ever Built

What Is a Load Box (And Why Should You Care)?

If you've ever wanted to crank your tube amp to its sweet spot without your neighbors filing a restraining order, a load box is your ticket. It sits between your amp's speaker output and... well, nothing. It soaks up all that power so you can drive your tubes hard, get that glorious saturated tone, and send a direct signal to your interface, headphones, or front of house. No mic. No volume. No angry landlord.

Two Notes has been the king of this game for almost two decades. Their Captor X and Captor X+ have been staples on pro pedalboards and in home studios for years. But with the Captor X Pro, they basically said "what if we rebuilt the whole thing from scratch and made it absurdly powerful?" And that's exactly what they did, in partnership with Ampete Engineering, the German wizards behind some of the most insane switching systems in the guitar world.

Everything the Captor X Pro Brings to the Table

Let's talk specs, because they're wild.

First up: 150 watts of multi-impedance load handling. That means 4, 8, and 16 ohm support all in one box. Got a Marshall running at 16 ohms? Cool. A Mesa at 8? Also cool. A weird vintage head with a 4 ohm tap? Still cool. One box handles them all. That's a big deal for players with multiple amps, because previous Captor models locked you into a single impedance.

The passive attenuator is where things get really interesting. Instead of the old three-level system, the Captor X Pro gives you 13 discrete attenuation steps, plus mute and full volume. That's a relay-controlled auto-transformer design, which means your amp's dynamics and feel stay intact as you turn things down. You're not squishing the life out of your tone just to play at bedroom levels. Every step is deliberate, repeatable, and programmable.

Then there's the triple-voiced load architecture. You get three options for how the Captor X Pro interacts with your amp: Reactive Natural (smooth, speaker-like, lots of bloom), Reactive Presence (tighter lows, more top-end bite), and Resistive (flat, controlled, and precise). Each one changes how your amp feels under your fingers. It's like having three different speaker cabs that affect your playing response, not just your sound.

The DynIR Engine Is the Real Star

Two Notes' DynIR technology has always been impressive, but the Captor X Pro takes it to another level. The True Stereo DynIR Engine lets you run two virtual microphones independently across the stereo field. Each one gets its own processing chain, its own positioning, and its own output assignment. Or switch to Dual Mono mode and route each mic to a completely separate output with independent cab, mic, and effects processing. For recording, that's an absolute game changer.

It ships with 24 premium DynIR virtual cabinets, and each one packs 8 microphone models with continuous positioning. We're talking front and back of the cab, close to room distance, center cone to speaker edge. Plus 12 studio-grade room simulations. The math on the tonal combinations here is honestly ridiculous. And if you want more, Two Notes has over 600 additional DynIR cabs available in their store.

The built-in effects suite is stacked too: an enhancer for frequency and dynamic shaping, a twin tracker for instant stereo double-tracking, a reverb with 12 models (including spring and plate), per-mic EQ, output EQ, a noise gate, and a tuner. Oh, and it comes with a lifetime GENOME license, which unlocks even more processing options including Astro Repeater, TetraVerb, Planet, and Aether effects.

The Routing Flexibility Is Nuts

Here's where the Captor X Pro really separates itself from everything else in the load box category. It has both a mono Pre-FX Loop and a stereo Post-FX Loop. Your compressors and EQs go in front of the Torpedo processing. Your delays, reverbs, and modulation go after. Clean signal path, full stereo width, zero compromise.

But here's the sneaky brilliant part: the Pre-FX Return doubles as a line-level input. That means you can feed external preamps and modelers directly into the Captor X Pro's Torpedo processing and stereo outputs. So if you're running Tonex captures or NAM captures through a dedicated hardware unit, you can use the Captor X Pro as your cab sim and DI stage. And the Pre-FX Send can be repurposed as a pure, unprocessed amp DI for re-amping later. Smart.

You also get 128 presets that recall everything: load settings, cab sims, mic positions, routing, effects, the works. Controlled from the front panel (which has a full color display and dual rotary encoders), via the Torpedo Remote app on your computer or mobile device, or through MIDI. Every parameter is accessible without a menu dive.

It's Also an Amp Capture Machine

Here's something the capture and profile crowd needs to hear. Two Notes specifically designed the Captor X Pro to be an ideal platform for amp capture and profiling workflows. The multi-impedance reactive load, studio-grade line outputs, and selectable load voicings give you consistent, repeatable results every time you capture an amp.

If you're making Kemper profiles, Tonex captures, NAM captures, HeadRush clones, or NeuralDSP captures, this thing is basically purpose-built for your workflow. The triple load voicing options alone mean you can capture the same amp three different ways and get meaningfully different results. Two Notes even offers their free Capture Studio application for making captures in both static snapshot and AmpNet multi-parametric formats.

For the rest of us who would rather just download killer amp tones that someone else already captured? Six String Lab has you covered. Our Kemper profiles, Tonex captures, NAM captures, HeadRush clones, and NeuralDSP captures give you access to tones from dozens of legendary amps without ever needing a load box, a tube amp, or a microphone. Just saying.

The Price and the Big Question

The Captor X Pro comes in at $1,099.99 USD (€999.99 in Europe), with pre-orders open now and shipping expected in early Q1 2027. That's not cheap for a load box. But honestly? For what you get, it's not unreasonable either. The previous Captor X+ runs around $500-600, and the Pro basically doubles or triples the capability in every category.

The real question isn't whether the Captor X Pro is worth the money. If you have a killer tube amp and you need to record silently, play at manageable volumes, or send a pristine direct signal to front of house, this is probably the best tool ever made for that job. Full stop.

The real question is whether you need a tube amp at all in 2026. Because here's the thing: between Kemper profiles, Tonex captures, NAM captures, and all the other capture platforms out there, you can get tones that are virtually indistinguishable from the real thing for a fraction of the cost. A $1,099 load box plus a $2,000 tube amp is over three grand before you even think about a cab. Or you could grab a solid modeler or capture rig, load it up with premium amp captures from Six String Lab, and be recording studio-quality tones in minutes.

We're not saying tube amps are dead. We love tube amps. But the Captor X Pro might actually be the strongest argument for going digital that Two Notes has ever accidentally made.

Should You Pre-Order?

If you already own a great tube amp and you've been waiting for the ultimate load box/attenuator/cab sim combo, stop waiting. The Captor X Pro is everything the Captor X should have been from the start, and then some. The multi-impedance support alone makes it worth the upgrade for anyone running multiple heads.

If you're still on the fence about whether to go tube or digital, maybe try both. Grab a free pack from Six String Lab and see how close modern captures get to the real thing. You might be surprised. And if you still want that tube amp magic with total volume control, you'll know exactly where to find the Captor X Pro when it ships early next year.

Either way, your tone has never had more options. And that's something worth getting excited about.

Check out the full Six String Lab collection for Kemper profiles, Tonex captures, NAM captures, HeadRush clones, and NeuralDSP captures. Whatever platform you're on, we've got tones that'll make you forget you ever wanted a tube amp. Or at least make you question it a little.
