DULCET 30

TWO CHANNEL 30 WATT TUBE GUITAR AMPLIFIER

(Dulcis Harmonicus Sustinens Infinitum)

Incandescent masterwork of the thermionic age, possessing the rare ability to recast crystal clear guitar signals into oceans of sustaining overtones through dominion over electron streams deep inside the immaculate voids known as vacuum tubes.

Caution: may cause perpetual note hang and neighborly discord.

Use the Bass Resonance Switch and Treble Impedance control to tube the load response.

Active in Silent Mode or when using Power Attenuators.

Three Analog Cabinet Simulator Outputs: XLR, 1/4" Line, and Stereo Headphones with analog "room effect"

Four Overdrive Modes available

Choose your desired headroom level for each channel

2-Button

illuminated footswitch for Channel Select and Reverb

Dual Power Attenuators for transparent Master Volume control of each channel

Six -3dB Attenuation steps

Bedroom Level mode for -30dB maximum attenuation

Uncompensated Line Output for use with external impulse response devices

Natural Sound

The Dulcet 30 simply enriches your guitar's unique sound. Enhance it further with the interactive 3-band EQ, independent Bright switches, and Presence control

Expressive Response

Touch-sensitive overdrive that reacts to playing dynamics and converts your guitar's volume knob into a "Drive" control. Designed for Fast attack with natural compression: enjoy superb articulation with zero stiffness.

Custom Tone Palette

Select from four tube Overdrive preamps. OVERDRIVE 0 is geared for clean harmonic sparkle, and OVERDRIVE 3 is ideal for chewy harmonic overdrive, but ALL MODES are capable of pushing the power amp into overdrive.

Select an Overdrive Mode for CH I, then use the Volume control to dial in your desired amount of overdrive (if any). Attenuate to your preferred listening level. Repeat with CH II, then use the footswitch to alternate between channels.

Harmonic Enhancer

Multiple Outputs

Three Cab Sim outputs (XLR, 1/4", Stereo Headphones with analog "room" effect) and a Direct Line Out with separate Level control

Speaker Flexibility

4, 8, and 16Ω Impedance Selector with 2 Loudspeaker Output jacks

Floor Control

Illuminated footswitch for channel and reverb switching

VIRGA™ Variable Reactive Load

A reactive load is a silent device that your amp sees as a real speaker cab, allowing cranked tone capture at any volume.

We ran extensive computer simulations and real-world tests when designing the VIRGA Variable Impedance Reactive Guitar amp Attenuator, to create a fully customizable response curve with performance rivaling the best load boxes on the market.

Use the Bass Resonance switch and Treble Impedance knob to adjust the VIRGA's impedance curve. Tune it by ear, or match it to your favorite speaker cabinet.

The Dulcet 30's onboard VIRGA activates automatically when the attenuator for the selected channel is engaged. To use it as a silent dummy load (no cabinet), simply unplug the speaker cable.

The Dulcet 30 and standalone VIRGA both come loaded with an analog Cabinet Simulator. Record at any volume (or no volume), run direct to PA, or partake in some late night headphone noodling.

Prefer to use an existing IR unit or plug-in? We included a direct line output for just that purpose.

Experience the pure dynamic tone of the Dulcet 30, at any volume, in any situation.
