Best amp I’ve ever heard or played
— Stuart Dixon, guitarist, producer, engineer
 

The Custom 44 is a fully featured amp based on the Safire. This example and its matching 2 x 12 cab were specified in Teal Blue with a stunning oiled ash front to the head.

Based on the 36-watt Safire, the '44' has a beefier solid state rectified power supply that gives a little more headroom and punch at the low end. A change in the voicing on the preamp extends the lows a little.  

The bias modulating tremolo comes with a foot switch-able speed control so the player can switch between fast and slow modulation.  The change in speed is not instant but takes a few seconds - just like a Leslie speaker.

This amp also features the foot switch-able More control adding more preamp gain and switching in a master volume control that has both attenuation and gain.  This simple control opens up so many tonal possibilities adding refinement to traditional "rhythm/lead" switching, maintaining the character of the single channel amp but with the required increase in gain, compression and volume.

The More function is linked in with the studio quality reverb, allowing the size and level of the reverb to be changed when switching adding another level of sophistication.

It puts out 44 watts through a pair of 6L6s and has a variable headroom control that allows the sweet spot to be found at any volume.

  • Three control preamp with Volume and High and Low tone controls
  • Three-position Voice switch:
    1. Bass light - keeps things really tight when the amp is pushed hard
    2. Mid focus - great for fattening up single coils
    3. Deep - big round cleans with vintage style break-up when pushed hard
  • Unique 'More' control
  • Bias modulating Tremolo with foot switchable speed
  • Lush studio quality reverb with four-way interaction 
  • Variable output headroom
  • Transformer balanced Cabinet Simulator Output
