A Load Box with Uncompromising Tone
The X-LOAD LB-2 Reactive Load Box is a high-quality load box with great features including front-panel output level control, a voicing switch, speaker thru capability, and both active and passive DI outputs. We designed the LB-2 because other reactive load boxes did not meet our needs, and we knew a great many guitar players would feel the same way. We needed a device that would react and interact with a guitar amp like a real speaker. It needed to be ideal for both live and studio applications, and above all else, it needed to sound great. Mission accomplished in the X-LOAD LB-2!
Speaker Reactive Load vs. Speaker Tone
When considering the X-Load LB-2, it is important to understand the difference between speaker load and speaker tone simulation. A guitar speaker cabinet has two significant effects on your overall tone. The first is caused by the speaker as a load which interacts with an amp. The speaker and cabinet dynamically affect the sound of the amp because of a reactive impedance curve. The LB-2 accurately emulates this effect using our proprietary Dynamic Impedance™ Technology, which changes the load depending on the power levels of the connected amplifier. This causes the guitar amp to interact with the LB-2 it as it would a real speaker. The result is unprecedented realism that other reactive load devices cannot match.
The second effect a speaker has on your overall sound is caused by the distinctive tone of the speaker itself. Guitar speakers are limited in comparison to full range speakers, with typical bandwidth in the range of 75 Hz — 5 kHz. The LB-2 X-Load does not simulate speaker tone, but this is by design so you can “re-cab” using the sophisticated speaker tone simulations in the Fractal Audio Axe-Fx, AX8, Cab-Lab, or 3rd party products.
The LB-2 also features a Voicing Switch for different options based on the behavior characteristics of real speakers. This switch causes your amplifier to behave differently—as if it were connected either to an iconic “UK” or “US” speaker load.
The X-Load LB-2 is built for years of reliable use and will satisfy even the most demanding players, producers and engineers both today and tomorrow, even as speaker tone simulation technology continues to evolve.
