The AMT K2 is a preamp and effects pedal from AMT Electronics, an analog preamp offering clean, low gain and high gain options1. AMT describes it as an emulation of Krank amps' custom sound: "The sound of K-2 is dense dryish high gain drive with a wide range of the channel working sensitivity"2. It is part of the LA2 line of the Legend Amp series of pedals, which AMT introduced as the next generation of that series2.
Sound and channels
The K2's drive character is the point of the pedal: AMT positions it as a Krank-style voice, with a dense, dryish high-gain drive and a wide range of channel working sensitivity2. The LA2 line acts as a two-channel preamp, providing a switch between clean and overdriven channels by means of a footswitch2. The CLEAN channel is universal for all models of the series and, in AMT's description, sounds in the style of classic Fender amps2.
AMT says the LA2 line's designs are original circuits developed by AMT specialists, which the company says allow a bright and rich sound in the style of original tube overdrives while using low-voltage (9V) power and low current consumption2.
Controls
| Control | What it does |
|---|---|
| OD LEVEL | Adjusts the overall loudness of the pedal output2 |
| HIGH | Controls the amount of high frequency in the signal2 |
| MIDDLE | Controls the amount of mid frequency in the signal2 |
| CL BOOST SWITCH | Engages a boost of clean signal up to +8dB when the pedal is bypassed, making the pedal a 2-channel preamp2 |
The pedal also includes a Noise Gate as a global setting3.
The CL BOOST clean level and clean boost controls when bypassed work only with the CAB SIM OUT and PREAMP OUT outputs, according to AMT2.
Power and connections
The K2 runs on 9-12V DC power with negative center (-) polarity, from an adapter or a battery2. That means it can be powered from a standard pedalboard supply or a battery when no supply is at hand.
It provides three outputs: CAB SIM OUT, PREAMP OUT and DRIVE OUT, all usable simultaneously2. That arrangement lets the pedal feed several destinations at once, for example a cab-simulated signal to a direct feed alongside the preamp and drive outputs.
When in effect mode, the LA2 series uses "partial" active bypass, which AMT says reduces the need to minimize the length of used cables and retains the original sound when the effect is off2.
Where it sits in AMT's range
The K2 is one of the Krank-style voice in the LA2 line of the Legend Amp series2. Players comparing it within AMT's wider preamp range will find other series voices such as the AMT P2, the AMT SS-20 and the AMT R2, and the full set of options is covered on the preamp pedals page.

Questions
What does the CL BOOST switch do on the AMT K2?
The CL BOOST switch engages a boost of clean signal up to +8dB when the pedal is bypassed, which turns the pedal into a 2-channel preamp. AMT notes that the optional clean level and clean boost controls when bypassed work only with the CAB SIM OUT and PREAMP OUT outputs.
Can the AMT K2 run on a battery?
Yes. AMT specifies 9-12V DC power with negative center polarity, supplied by an adapter or a battery, so the pedal can be powered either way.
Which AMT series is the K2 part of?
The K2 belongs to the LA2 line of the Legend Amp series of pedals, the next generation of that series according to AMT Electronics.
What is the AMT K2 clean channel like?
AMT says the CLEAN channel is universal for all models of the series and sounds in the style of classic Fender amps, so it is shared across the LA2 line rather than voiced to match the K2's Krank-style drive channel.
What are the AMT K2 dimensions?
AMT lists the pedal's size as 110 x 62 x 58 mm, which the company describes as a small size.
