The VHT Special 6 is also a great deal for anyone looking for an affordable, all tube amp with versatility and gain. It’s got the standard Overdrive and Clean inputs and the associated overdrive, tone and volume controls.
What makes the VHT Special 6 Ultra different is that the volume control has a pull boost which acts as a mid-range gain. The Depth control allows you to vary the low frequency roll off point. This helps you to sculpt your sound the way you want it for various pickup and cabinet pairings. Also unique to the Ultra is the “Ultra” control knob which controls the level added gain to the output for maximum overdrive.

The VHT Special 6 Ultra also has a power-attenuating watts control. This lets you dial in the output wattage from 0.5w all the way to 6w. It’s an excellent feature for those looking for an all-tube practice amp that won’t shatter the windows in the bedroom.
Lastly, the VHT Special 6 Ultra features two speaker out lines and variable impedance for 4, 8 an 16 ohm speaker cabinets and an effects loop.
Like its big brother (the Special 12/20), the Special 6 Ultra ships with a 6V6 output tube. This gives the Special 6 sweet Fender-like clean and rich overdrive tones. The dual 12AX7 tubes in the preamp are stock, but it can accept a wide range of alternate output tubes as well.
