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 2x12 Open Backed Cab, and Green for a 4x12 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!

Important Notice!

The Ampster does not come with an included PSU due to various import regulation in different countries.

The Ampster power requirements are 1000mA, as it’s run on around 5-600mA when on, though at start up it require up to 1000mA.


We recommend the use of a good high-quality digital PSU that delivers a good 1000mA like the Carl Martin PowerJack or similar,

Just thought I'd give you a quick update on the Ampster! I received it on Fri, 4/8, and then took the plunge and used it at a gig on Sat. (pics attached.)


Overall, VERY cool! I am quite impressed with the tone and the build quality. (I'd expect nothing else from Carl Martin and that is why I wasn't too worried about ordering sight unseen/unheard.)


I've been on the list for a Fractal for a while but in the meantime, have been using a Simplifier for a direct option. I haven't been that happy with the results and honestly would much rather use my amp (Bogner Shiva.) However, silent stages are taking hold and more and more bars/clubs are curbing higher volume.


I'm still undecided if I will pursue the Fractal but for the time being, the Ampster IS my solution. I love the tone and the feel. I used the 4x12 cab sim for most of the night as the 2x12 really takes some eq adjustments. (I didn't have space for my Plexitone so dug out a Weehbo JCM Drive Ltd that I had hardly used. Not bad but the Plexitone has a more Marshall kerrang to it, I think.) Anyway, great sounding unit and I like how simple and straightforward it is.
