GrandMeister Deluxe 40 combines all-tube tones and smart control features in a supremely playable package! On top of its plethora of amazing sounds, every knob and switch setting on GrandMeister Deluxe 40 can be easily saved, stored and recalled at the touch of a button, and the studio-quality on-board effects settings are saved right along with the gain and EQ knob values.

Deluxe Tone Technology
Can you imagine having instant access to any iconic all-tube guitar sound you can imagine? GrandMeister Deluxe 40 gives you exactly that – a stunning sonic experience and a whole new level of guitar tone quality – thanks to Deluxe Tone Technology, which pairs groundbreaking new circuit design advances with renowned tone-shaping capabilities, all inspired by H&K's flagship TriAmp Mark 3. From sparkling vintage clean to throaty crunch, a beefy brown sound and crushing levels of all-out gain, sonic freedom the touch of a button away with GrandMeister Deluxe 40!

Save your favorite all-tube tones with the push of a button
Saving and recalling your favorite GrandMeister Deluxe 40 sounds is an exercise in convenience with the optional FSM-432 MK III MIDI board, which lets you store up to 128 presets and recall them with the tap of a toe. All of the amp’s parameters are saved, including gain, EQ, and all effects settings, giving you a practically inexhaustible library of different sounds. Pot values are saved via the company's ingenious Smart Rotary Control technology – which also lets us keep the GM40’s panel clean and easy to use, with only 9 pots instead of 14 per channel!

Channels and FX
With GrandMeister Deluxe 40, there’s a channel and accompanying effect to suit every six-string style. The Clean, Crunch, Lead and Ultra channels can be sculpted to your heart’s content with the powerful EQ and gain controls – and don’t forget the Boost, which kicks specific frequencies up to 11 to give you snappier, creamier or beefier tones, depending on your selected settings. On top of that, you can layer on lashings of studio-quality reverb, delay and modulation effects (choose from chorus, flanger, phaser and tremolo) to take your tone to new levels!

Amazing all-tube recorded tones without mics
Red Box AE is the latest version of H&K's award-winning DI box with speaker emulation – and it’s built into GrandMeister Deluxe 40, meaning you’ll never need to worry about where to place your cab mic again, onstage or in the studio! Red Box AE’s DSP-driven Ambience Emulation authentically mimics that room-filling sound of a 4×12 cab and delivers an ultra-direct attack of pure tube tone goodness by tapping your signal between the power amp and the Power Soak.

Rock on Stage. Play at Home. Record at Night.
GrandMeister Deluxe 40’s luxurious appointments and smart features like the built-in power soak give you everything you need to rock the world’s biggest stages, enjoy Deluxe tone at an agreeable room volume at home, and silently capture spine-tingling tones at night without a cab or microphone. This is truly the definitive do-it-all all-tube amp!
