The DSM Humboldt Simplifier mk-II Zero Watt Reverb Stereo Amplifier takes the analog amp simulation to a new stage of realism. Much more options, while keeping the instant touch and dynamics that only an all analog device can manage.

Pre-Amps to the limit

• Completely redesigned preamps with wider gain options
• AC BRIT Preamp minimizes the MID Control range resulting on a more accurate historic behavior, like a VOX AC-30 64' Top Boost channel.
• American (USA) Preamp is now based on a true classic: The Bassman 59'
• MS Brit performs a high level of gain, just like a hot-rodded Marshall Plexi.

The Power Amp

• A Dedicated power amp drive allows you to dial the perfect amount of power amp compression for that sweetspot that only a tube amp can achieve. This controls sets a deeper level of realism engineered only by DSM Humboldt.
  
• The POWER AMP is a highly detailed reproduction of a Class A/B power stage, including the phase inverter. Each power type reconfigure the feedback path, PI gain and the effect of the power transformer on the power tubes.
• A Clip indicator shows when the emulated power tubes are clipping, helping you to find the desired sweet spot between power drive and preamp drive, as it would be on an actual tube amplifier.
• In combination with the MASTER VOLUME, you can get any amount of pre and power amp drive at any volume level.

The Master section

• MASTER VOLUME allows you to set any amount of pre and power amp drive at any volume level, avoiding unwanted FX-LOOP distortion.
• Re-designed PRESENCE Control within the power amp feedback. Clockwise it boosts the mid-highs like Marshall and Fender. Counterclockwise it cuts the Highs like a VOX amp.
• Re-designed RESONANCE Control that allows you to set the low-end thump according to your PA system.

Stereo Cabsim

• After a comprehensive research based on hundreds of response curves from the most renown speakers in the market, DSM completely redesigned the Cabsim section, replacing the MIC position control for a more useful yet intuitive three profile speakers control:
• BLACK: Based on the V30 Speaker
• BLUE: Based on the Blue Alnico Speaker
• GREEN: Based on the G12 Greenback Speaker
• Three Classic Cab types:
• COMBO (1x12" Blackface style Cab)
• TWIN (2x12" AC Style Cab)
• STACK (4x12" 1960 Style Cab)

A Built-In Reverb

• According to many users, one of the most desired features on the OG Simplifier was a built in reverb, or at least a room control.
• This is why, DSM heard this call by loading this Simplifier with a side-chained digital PLATE reverb.

Updated enclosure

• With a redesigned layout for an easy understanding and connectivity, will help you to keep your Simplifier as your pedalboard brain, better than ever.
• Also DSM included a heavy-duty all aluminium enclosure, with all metal switches for maximum endurance.
