L12X is an analog simulation inspired by the Marshall® Lead 12™ solid state amplifier of the late ‘80s.

Current version: v1.1.2 (Sep 2020)
The original head was an op-amp based amplifier: instead of using tubes or transistors, the op-amp is able to provide a huge amount of gain with very little or no distortion. However, when the amplified signal reaches the voltage applied to power the op-amp, it gets clipped. Marshall engineers exploited that to provide a great sounding amplifier with very few components.

This little solid state head is able to push cabinets up to 4×12 and can easily sound like a JCM™. We modified the original circuit by adding a Contour knob (to get a more scooped tone) and an additional Boost overdrive stage. We also included an integrated Cab Simulator, loaded with a Marshall cabinet IR featuring Celestion V30 cones.

    I am speechless…
    This is undoubtedly the best free amp sim I’ve ever used and frankly, better than a lot of paid ones I’ve tried in the past.
    Granted, it depends on alot on your taste and the tones you are looking for but I could not be more pleased. Would recommend for everyone to check this out.

    (I ran my guitar through a logic compressor, prex7, and then this)

    How can I download this plugin? I don’t see the download link.

      You have to go through the order process, like a regular product.

    I review and use amp sims every single day for http://www.honestampsimreviews.com and the L12X free or not is one of my favorite sims on the market today. Clean tones to death metal and beyond are easy to find but the higher gain stuff requires a tube screamer or something to give it a bit of a push. Overall, in my opinion the L12X is the most versatile free amp sim made to date. .

    Is it really free? How long can we use it? Is there an expiration period? Can we use in Mac?

    • Luca Capozzi


      Yes, it’s free. No expiration date. You can use it as long as you want and it works on Mac too.
