The RockCrusher is a seriously impressive attenuator – it’s not just dumbly loading your amp. Rivera’s reactive design keeps the amp’s voicing intact even at bedroom volumes, and the EQ section lets you shape the tone. Perfect for players who want to crank their tube amps without disturbing the neighbors, and who prioritize authentic amp tone over sheer volume reduction.

Frequently Asked Questions
A resistive load simply absorbs power, potentially altering the amp's sound. The RockCrusher's reactive network mimics a speaker's impedance, preserving the amp's tonal characteristics more accurately.
Yes, the RockCrusher functions as a power soak, meaning it can be used directly with a power amp section, though its reactive design is optimized for amp/head combinations.
The EQ is surprisingly effective for subtle tonal adjustments – it's not a drastic overhaul, but it allows you to fine-tune the attenuated sound to your liking.
