Loadbox Comparison for Guitar: OX vs Bugera vs Two Notes vs RedSeven
If you want to run a tube amp silently, record direct, or tame volume without losing feel, a loadbox is one of the best upgrades you can make. Below is a clear comparison of four popular options, with a focus on real-world use: silent recording, cab simulation, workflow, and live practicality.
Scope note: “Two Notes Torpedo” comes in multiple models. This comparison treats it as the Torpedo Captor X style solution (reactive load + IR/cab sim workflow), since that’s the most common modern use-case.
Comparison Table
| Product | Best for | Reactive load / silent recording | Attenuation to a real cab | Cab sim / IR flexibility | Editor / workflow | Notable extras | Main drawback |
|---|---|---|---|---|---|---|---|
| Universal Audio OX | Studio-style “finished” mic/room tones fast | Yes (premium reactive load category) | Yes (multi-step attenuation) | Strong, curated cab/mic/room workflow | App/software control is central to the experience | Multiple outputs; designed as a recording front end | Typically the most expensive; you’re buying into UA’s ecosystem |
| Bugera PS1 Power Soak | Cheap way to turn down a loud amp | Acts as an attenuator/load solution (up to 100W class) | Yes (this is the whole point) | No built-in IR loader / modern cab sim | No editor | Budget-friendly and simple | Not a complete silent-recording solution without extra gear (IR loader/cab sim) |
| Two Notes Torpedo (Captor X style) | Versatile direct rig + strong app control | Yes (reactive load for silent use) | Yes (model-dependent across the Torpedo range) | IR-based cab sim; flexible ecosystem | Yes (app-driven workflow) | Routing/tone tools vary by model | Impedance and features depend on the exact model/version you buy |
| RedSeven AmpCentral EVO Winner | The most complete “gig-to-studio” all-in-one | Yes (100W RMS / 8Ω reactive load) | Yes (built-in attenuation option) | Dual independent IR loading + modern direct tone shaping | Free editor for iOS/Android + Mac/Windows | Integrated noise gate + multiple power amp simulations + built for modern direct rigs | 8Ω-only reactive load, so confirm compatibility with your amp’s output tap/use-case |
