Victory V4 Duchess Power Amp (Original)

V4 The Duchess Guitar Amp
Powerful, ultra-compact and lightweight single-channel guitar amplifier for home, studio and live stages
Four valves in the front end, 180-watt power section, reverb and tremolo. Only 1.7kg / 3.75lbs – a guitar amp revolution!
V4 The Duchess partners a V4 Series all-valve preamp with a solid-state, 180-watt Class D power amp. Its ultra-compact size and negligible weight disguise the huge tones it can produce. It's great for home and studio players looking for an elegant solution on a small cab or desktop, or for touring musicians who need a great-sounding, dependable pedal platform amp.

Features:
Volume and Master - Balance the front end preamp gain with the overall volume output. It will overdrive in the preamp slightly should you want that, but the main goal is higher-headroom tones and power.
Three-Band EQ - Powerful bass, middle and treble controls to shape your tone. These also have an effect on the gain character and drive levels – just like in any valve guitar amp.
Reverb - Lush sounding digital reverb gives you ambience aplenty. Run it low for a subtle feeling of space, or max it out for washy, splashy hugeness!
Tremolo - From slow and pulsing to fast and staccato, we’re suckers one of the oldest effects in the book.Turn it on/off on the chassis, or remotely.
Series Effect Loop - Sits between the preamp and power amp. Run your time-based effects here for maximum clarity.
Balanced Line Out - Send a direct feed to a separate speaker simulator, front of house or wherever you like. Can be used with or without a speaker connected.
9V DC Power Output - Want to power some extra pedals and stick this on your board? We've included a 9V DC centre-negative output that will put out a maximum of 500mA. This is more than enough for the vast majority of drives, fuzzes and analogue delays and so on.
Speaker Cabs, Power & Impedance
Speaker choice is critical with V4 The Duchess Guitar Amp

V4 The Duchess can put out a staggering 180 watts at 4-ohms (through the Victory V112 Neo cabinet, for example). However, 4-ohm speaker cabs aren’t exactly common, and nor are single speakers that can take 180 watts, so please proceed with caution with a 4-ohm load.

However…
The nature of Class D, solid-state power sections such as this means that the amp’s output is dependant on the speaker load. If you use a more common 8-ohm cab, output power drops to approximately 90 watts. 16-ohms gives you a still-very-healthy 45 watts.
The principle reason we went with the 180-watt output is because lower-powered solid-state devices can run out of volume and headroom very quickly once you get to 8- and 16-ohm loads.
No such problem here: there’s plenty of power no matter what cab you use.
