FROM CLEAN TO EXTREME

Congratulations and thank you for purchasing the LA 25 MKII. This Amplifier was designed 

to inspire you and elevate your playing all the way to the highest level. We really took the 

long road on designing the LA 25 MKII because repeating ourselves was not an option. 

We decided to take on the challenge and break a new ground. First of all we went for the 

world wide renowned clean and functional Swedish design, using only the highest quality 

components and materials available on the market today. Second we went for making it 

logical and easy to operate and really improve both tactical and visual ergonomics for fast 

operation and visibility of functions even in the dark. We are very proud to have achieved 

building a power house amp under 7.8 Kg with it’s small physical footprint making it 

possible to bring as a hand luggage on an airplane. 
We also engineered everything in a 19“ Rack 3U format with only 17 cm depth. It can work 

in any situation since you can put it in a studio rack, touring rack or even in a wooden headshell 

if you would like to have that classic look of an amplifier. We packed it full with so many 

features, some never done before like: 

a built in Re-Amplifier, a DI, a Virtual Mic speaker 

simulator and a reactive load in one amp.

 You can use the LA25 MKII without any speaker 

or an external load. The possibilities are limitless. 
The original LA 25 has its own signature sound slightly darker and softer with just a slight 

touch smoother top end in the Crunch and Vintage modes.The choices we made to alter the 

core DNA of the LA 25 MKII resulted in a new brighter sonic palette and quite alot more gain. 
As any other of our devices , this one requires very little care and just a little bit of attention to our 

recommendations regarding maintenance. Please spend a couple of minutes to read this manual so 

you can get the most out of the product. Remember and implement these few recommendations 

for handling the product and you will be able to operate it for many years to come. 

We hope you’ll enjoy this product 

just as much as we enjoyed designing and making it

Before going any further, make sure that your amplifier 

is compatible with your mains electricity supply.

The 

(a)

 voltage selector must be set to match the local 

power grid. The 

(c)

 fuse must match the local power 

grid and the 

(a) 

voltage selector. Check what is written 

in the field 

(d)

. If it matches the local power grid, you 

are good to go. If it doesn’t match, the mains fuse has 

to be changed.

Mains input & fuse: 

The specific mains input voltage 

rating that your amplifier has been manufactured for 

is indicated on the rear panel of the amplifier. Your 

amplifier is provided with a detachable mains (power) 

lead, which should be connected to the 

(b)

 

mains 

input

 socket on the rear panel of the amplifier. The 

correct value and type of mains fuse is specified on 

the rear panel of each amplifier. 

NEVER

 attempt to 

bypass the fuse or fit one of the incorrect value or 

type.

Changing the mains fuse: 

Make sure that the mains power lead is unplugged; Make sure that the 

(21) voltage selector is set properly; Open the (23) mains fuse socket lid; Replace the fuse; Close the lid.

Transporting your equipment: 

Please ensure that your amplifier is switched off, unplugged from 

the mains electricity supply and that all removable cables have been disconnected from your 

equipment before attempting to move it. Keep the original box in case of shipping the amp to us 

for repair or replacement. 

Important set up information: 

Failure to select the correct impedance may damage your 

amplifier.  If connecting a speaker cabinet make sure that you use a proper speaker cable. Never 

use a screened (shielded) guitar cable for this purpose.
