• Introducing the Retrofier Roadtripper...

    "Warm Glow"™!

  • (Actual product image coming soon)
  • We still have work to do to create a "Warm Glow"™ page, however for those of you already familiar with the pedal, we wanted to at least give you a means to order one.

    In a nutshell, QES set out to develop a pedal with authentic tube amplifier tone using our proprietary SST (Solid-State-Tube™) circuit with tone and dynamics that are indistinguishable from actual vacuum tube guitar amps. The "Warm Glow"™ has proved to be that pedal!

    Please visit our web site again soon and look for the new "Warm Glow"™ page.

  • The Retrofier Roadtripper MCM™ in action
  • The clip below demonstrates the Roadtripper MCM™'s incredible sound quality as heard from it's own balanced line output.

    What you hear in this clip is the amp directly fed into a digital audio recorder while under test in the QES lab. The tone controls, tremolo, and spring reverb are all being used. The feel of compression is actually the tube effect of our very unique preamp circuits. Post production compression was not used.

  • "Blues on a Strat" Retrofier™ style
  • Tom Harter, a finalist in the Guitar Center "King of the Blues" competition in Appleton WI, test drives a Roadtripper MCM™ during Jason Goessl and Kate Voss's fall tour 2016. Tom's guitar is going directly into the amp using it's beautiful spring reverb and tremolo. No pedals to be found. The Roadtripper MCM™ can't help sounding incredibly huge despite the casual cell phone recording.
