The Tone King Ironman II was designed specifically to tame powerful tube amps. The compact attenuator is designed for amplifiers up to 100 watts into 4, 8 or 16 ohms and reduces the output volume of the amp without compromising the sound quality. To achieve this, the Ironman II mirrors the impedance curve typical of guitar speakers to faithfully reproduce sound and attack. The overall volume is easily reduced in six switchable steps , while the Range switch with HI and LO modes provides two different levels of power reduction for each position of the Attenuation Level control . The SOLO switch gives a switchable boost to the signal for leads. Furthermore the Ironman II features a Presence Switch with three steps of adjustable treble and compression , while the rear line out and included footswitch allow for seamless integration on stage and in the studio.
