Boss katana artist mkii12/29/2023 ![]() ![]() The effects section is followed by controls for Presence, Master volume, Solo volume and Power Control, which switches the Katana’s output stage from a maximum 100 watts to 50 and 0.5 watts, with a standby/mute option. ![]() Illuminated selector switches light up in different colours to tell you which effect is active, and there’s also a tap tempo button. The reverb slots can be combined with delay for more flexibility. There are 30 onboard effects slots, including six for reverb, split into two banks and grouped in three colour-coded slots for ease of recognition. Two pairs of dual-concentric knobs handle boost, modulation, effects (non-modulation stuff such as wah and octaver) and delay, with a third control knob for the Katana’s digital reverb. Reassuringly standard-looking knobs handle gain, volume, bass, mid and treble functions, followed by level controls for the Katana’s built-in effects. A Variation button accesses five alternatives, for a total of 10 amp sounds. There’s a single input jack, followed by the amp-type rotary selector, which dials in one of five original Boss amp sounds: Acoustic, Clean, Crunch, Lead and Brown, this last one derived from the critically acclaimed Boss Waza head. The control panel is logically laid out, with clear white screenprinting on a satin black background for high visibility. There’s no universal mains input our sample Katana‑Artist II is for 240 volts and cannot be switched to operate in other countries with different wall mains. Smaller boards support power supply and input components, while the dominant features are a massive heatsink for the output devices and a substantial mains transformer. The components are mostly miniature SMD, with a large printed circuit board sat vertically behind the control panel and a horizontal main board toward the back of the chassis.Ī number of proprietary Roland chips occupy the main board, including the ESC2 sound engine, which is common across a number of Roland products. The particle board case surrounds a robust open-ended steel tray chassis containing the Katana’s electronics, with a front-facing control panel that’s unique to the Artist amps.Īs you might expect, the circuitry has very little in common with a conventional guitar amplifier and looks more like it could have come from one of Roland’s synthesizers. ![]() This new head features similar visuals to the rest of the range, clad in smart black vinyl accented with silver trim and white control-panel graphics. The combo amp has been available for some time and, now, for those ready to stamp some real authority on their tone, Boss has introduced the Katana-Artist II head, together with a matching 2x12 G12W-loaded guitar cabinet. ![]()
