The Classic Combo Amp

An all new generation of analog guitar amplifiers has finally arrived!

Get ready for something VERY different in guitar amplification because the
classic is here! We are not talking about a new flavor of what's out there. This is a completely new approach inspired by the best of the classic guitar amplifiers while adding qualities only dreamed of in the past and rolls them up into one incredible new product that can only be described as surreal.

The
classic combo guitar amplifier is not tube, not digital, and in no way behaves like a conventional solid state amp. It is a truly unique product that has at its core the Solid-State-Tube™, an innovative new circuit module developed by QES that generates the harmonics and dynamic behavior of a class A push-pull tube circuit while leaving the high voltage, noise, weight, and other annoyances behind.

Inside the classic's vintage style cabinet with it's 12" Jensen^® guitar speaker, is a very fresh new approach to guitar amplifier electronics. QES's unique analog signal processing techniques give it incredibly versatile performance. This amplifier was carefully engineered and designed for and by guitarists and recording professionals. After such continuous scrutiny and critique throughout the development process, the classic has taken on a life of its own.

Classic Controls

The classic control panel is organized in the order of the actual signal flow from the input jack to the volume control. Other than the fact that the Low, Mid, and High controls are actually one unit and thus one stage, the signal flows through the amp from left to right as the controls appear.

• Very similar electronically to a typical tube amp input
• 1 meg ohm input impedance and about 10 PF capacitance prevents loss of signal quality and tone due to instrument cables and guitar circuit losses
• Exceptionally low input noise for an acoustically transparent connection to the guitar
• Subsonic filtering eliminates thumps, thuds, and other non musical disturbances

• Selects 6 levels of input sensitivity from clean to crunch
• Automatically compensates the output level for each setting
• Automatically adjusts the bass level for optimal tone balance at high drive levels

• 3 band constant Q graphic equilizer
• Band centers: 62.5 hz - 500 hz - 4 khz
• 24 db adjustment range per control

• Real spring reverb
• Exceptionally low noise
• Subsonic filter eliminates crash thumps, amplifier overload, and wasted power
• Advanced drive and recovery circuits with high end audio specifications capture spring nuances not normally heard
• Professional quality band limiting filters reduce noise and reverb "crashes"
• Natural mixing at all reverb levels

• Electronically logarithmic for smooth control from 0 to 10
• Lowers the noise with the volume level for exceptionally quiet practice level playing
• Zero DC minimizes scratchy pot noise

• 24 Volts DC, single polarity external power supply with Energy Star Level VI efficiency
• Worldwide power compatability by using simple travel adaptors or changing the power cord
• Real jewel style pilot light with 24 volt bulb
