Special thanks to Shnobel Tone for the great demo/promo video!

    Finally! An analog tube amp simulation pedal that REALLY works!

    The "Warm Glow"™ uses a revolutionary new analog transistor technology that produces an unprecedented tube amp simulation!

    Our pedal uses the proprietary QES SST (Solid-State-Tube™) circuit with tone and dynamics that are indistinguishable from actual vacuum tube guitar amps!

    "Warm Glow"™ demo sound clips!

    • Blues band 1
    • The setup on this one uses an electric guitar(Tele) plugged directly into the "Warm Glow"™, then with a balanced TRS cable plugged into a USB interface. From here it goes into a computer running a Digital Audio Workstation program(DAW). The session has a drum track, two takes of the guitar and one take of an electric bass fed into the same "Warm Glow"™. The only effect added by the DAW is reverb and there is no post production compression for the mix. In fact, there wasn't any mixing involved. The "Warm Glow"™ has such wonderful natural tube style compression even when clean, that mixing is very soft and effortless.

    • Blues band 2
    • This one is the same setup as above but without bass and a bit of delay on the lead.

    • "We Shall See" solo - original "Retrofiers" song(our band)
    • This one is a clip of two stem tracks which are both direct recordings using the "Warm Glow"™, from one of our original songs.

    • 335 Jazz guitar 1
    • This one uses a 335 type Jazz guitar with flat wound strings and a single P90 single coil pickup in the neck position.

    • What about bass through the "Warm Glow"™?
    • This is a really simple clip of just an electric 4 string bass plugged into the "Warm Glow"™ running direct into the DAW with just a touch of reverb. All that big fat warmth and tone is pure "Warm Glow"™!

    • Blues harp through the "Warm Glow"™?
    • Stephen Maxwell plays into his new "Warm Glow"™ direct, giving him some really nice overdrive and great tube tone. Thank you Stephen for the clip!

    How did you hear about us?

  • Retro style Combo Guitar Amp with Tremolo and Spring Reverb!

  • The Retrofier Roadtripper MCM™. The first truly "tube simulating" ANALOG solid state amp!
  • Yes there are so many amps and pedals out there making all sorts of claims, but we can gaurantee you that this one is one of a kind. The Roadtripper MCM™ must be heard to be believed. The sound is as retro as the look and has many tube lovers and "tone freaks" scratching their heads :)

    The MCM™'s circuits rival the quality of high end mixing consoles and include proprietary QES techniques that produce tube characteristics that can even outperform tubes!

    The 3 band constant-Q EQ is precise and covers a wide range of tone, the tremolo has a very wide range oscillator and 100% modulation giving some dramatic effects from volume swells to sci fi. The spring reverb is driven by a QES tube simulation and recovered with exceptionally low noise producing a range from sweet background fill to dripping surf.

    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.

The Roadtripper MCM™ can't help sounding incredibly huge despite the casual cell phone recording.
