Boss Waza Tube Amp Expander Core: The Perfect Companion for Tube Amps
The Boss Waza Tube Amp Expander Core is an elite recording and performance solution designed to capture the authentic soul of your tube amplifier. Leveraging Boss's Tube Logic philosophy, it acts as a high-fidelity reactive load that preserves the complex interaction between your amp's output stage and the speaker. This ensures that the tactile Response and nuanced Dynamics of your gear remain intact, even when recording silently or playing at home levels.
Master Your Tone at Any Volume
Equipped with a built-in 30-watt reactive drive power amp, the Expander Core allows you to crank your tube amp to its "sweet spot" for maximum saturation while controlling the output volume seamlessly. The revolutionary Air Feel technology recreates the "amp-in-room" experience, providing depth and atmosphere that traditional direct boxes lack. With 22 onboard cabinet emulations and 64 user IR slots, you have total creative control over your Tone.
Critical Technical Compatibility Note
While the Expander Core is designed to handle the majority of tube amplifiers up to 100 watts, certain designs are technically incompatible. Important: The Mesa Boogie Dual Rectifier and Triple Rectifier amplifiers are not supported by this unit due to their specific transformer and circuit behavior when connected to this reactive load system.
