Egnater Tweaker 40w Guitar Amp Head


Building on the amazing Tweaker 15 from Egnater the Tweaker 40 is more powerful, and somehow even more versatile live than its smaller brother. With 6 different tweaker switches controlling 2 channels with seperate master volumes you have real control over your tone in this all valve amplifier.

So Much Control

There is so much to talk about with this amp it may sound a little daunting. Trust us that it is so easy to work your way around and to dial in the tone you are looking for. Starting off you have two channels each with their own independant master volume and gain controls but with a shared EQ.

This EQ has the option of being set up in one of three modes; USA, AC or Brit. In USA mode the midrange is a bit more scooped and you get a much thicker and warmer sound. In AC mode you get some classic chime that you would have heard from bands like Queen and Fleetwood Mac, Finally in Brit mode you get that bitey black and gold amp tone heard on all kinds of different blues, rock and even metal albums.

Looking again at the different channels it is not quite as simple as just a gain and volume control. Egnater have added 5 different switches on each of the channels that are completely independant.

  • Vintage / Modern: Sets the feel and response of the amplifier to fit either more classic loser tones or more modern options with tighter attack.
  • Tight / Deep: This sets the low end response of the channel.
  • Bright / Normal: Increases the high end of the amplifier to add edge to warmer pickups.
  • Hot / Clean: Think of this as your modes. Clean goes from crystal clear to crunch and Hot takes you from crunch to crushing high gain.
  • Mid Cut / Normal: This scoops out the mids in the up position for smoother blues tones.

If you love playing a lot of different styles but don't want to fill your house with tonnes of amps for every situation the Tweaker is the perfect option. It is not very often that you get this much control out of an amplifier let alone one that delivers 100% real tube tone.

40w Of All Valve Power!

Most other amps that offer you this range of tones use some kind of digital modelling technology. While it works digital amps will never quite the same feel and response of a real valve amp which is exactly what this is. Using a pair of 6L6 tubes in the 40w power amp and a trio of 12AX7 valves in the preamp you know you will get some powerful tones out of this head.
