A stompbox that took over three years of development, the Carl Martin Ampster is the Danish company’s take on the tube power amp + speaker simulator pedal. In case you are wondering, yes, it has a little bit of a British flavor when overdriven, just like many of Carl Martin’s popular Plexi-style pedals.
Responsive to your performance and organic-sounding, this fully analog unit features a single tube-driven power amp and a speaker simulator, and can either supplement your amp with extra gain/sculpting options, or replace it entirely for an ultra-portable rig.
Featuring a set of control identical to the ones found in many cabinets (Gain + 3 knob EQ + Presence + Master), the Ampster adds two footswitches for Mute and Cabinet, which switches the Cab simulation from a 2×12 Open Backed Cab (Red LED) to a 4×12 Closed Back Cab (Green LED).
The backplate of the Ampster offers generous routing capabilities, including Link (amp output), a Balanced out, and an effect loop for those effects that sound better after the amp. A Voicing switch that delivers three bass settings. The Remote in allows controlling the cab sim footswitch remotely.
Here are the first videos of the Carl Martin Ampster.
Builder’s Notes: Carl Martin Ampster
The world of music has changed and the world of guitar playing has changed along with it. It is becoming normal to not see the full guitar rigs of the 70’s 80’s and 90’s, and just see guitar players with minimal systems to achieve their signature sounds.
Introducing the Carl Martin Ampster…. from the company that has shone the single analog light down that deep digital tunnel. The Ampster, a single tube driven amp/speaker simulator that can either supplement your amp, or replace it. A fully analog unit with controls that are the same as your amplifier with the addition of a mute switch, a speaker selection switch and a voicing switch. What’s more important, the Ampster reacts to your playing in the same way your full size amp does, giving you the same organic feel with zero latency!
The Ampster is housed in a solid metal box with the standard EQ (Bass Middle Treble), pre and post volume/gain controls (Master & Gain) plus a Presence Control. There is a Mute Switch for obvious reasons and a Cabinet Switch with an LED Indicator light ( Red for a 2×12 Open Backed Cab, and Green for a 4×12 Closed Back Cab).
On the back of the pedal you will find a Ground Lift and a Voicing Switch (a subtle low end cap controlled voicing adjustment). Input, Link (output to your amp) Balanced DI (XLR output to go to a mixing or recording console), a Send and Return for those specific effects that shouldn’t be in front of the amp, a Remote Input (cabinet sim) for use with digital or analog effect controllers like the Carl Martin Octaswitch ‘The Strip’, and your standard 9v 1A power input. It couldn’t be simpler!
Plug your guitar straight in, or plug your pedal board into the input jack, choose your output, and open your ears to a surprisingly big round clean sound. By adjusting the Gain, you can get a hint of that decidedly British Overdrive sound for which Carl Martin has become so well known, depending of course on the guitar and pickup configuartion. Our test players have fallen in love, telling us the Ampster reacts just like their standard amps, organic and responsive to your playing style or attack. In fact, the Ampster sounds just like a full size amp, but it fits on your pedalboard. Take a look at the videos…we are certain you will want to take the Ampster for a test drive!
