Get started with DIY and build your own professional reamping box with our most popular kit. The L2A is a rugged, sonically transparent re-amplifier that just happens to be a DIY kit. It's also a simple, fun DIY kit that happens to be an excellent piece of studio gear.
Unrivaled feature set. The L2A is the only passive re-amplifier to feature a Neutrik combo XLR/TRS input jack. No need to grab a TRS-to-XLR adapter.
The L2A’s three-way filter switch makes re-amping any source imaginable a breeze. The low-pass filter (LPF) tames high-frequencies, useful for mellowing out guitars and other bright sources, while the high-pass filter (HPF) is perfect for tidying up the low-end and sub-bass frequencies.
The fun part. Designed specifically for DIY beginners, the L2A presents no risk of electrical shock, consists of only a few parts, and can be built in about 30 minutes. Step-by-step instructions are available at diy.re/l2a-manual
Estimated build time: 30 minutes
Make something great. The L2A multiplies the sonic possibilities of your recording setup by letting you plug the output from your computer, mixer, or tape machine into your guitar amps and effects pedals. Suddenly, all of your guitar gear becomes another set of tools for adding excitement, depth, and harmonic saturation to your pre-recorded audio.

Customer Reviews
I should have done an unboxing video, it was put together so nicely! All parts are top quality, from the custom extruded metal housing to the heavy duty PCB. Designed for an easy build with basic soldering skills. A parts list would be nice for a larger project, but its lack was no problem here. The directions provided step by step photos which make all clear. Build took 40 minutes at a leisurely pace. Set up for use was easy and in less than 5 minutes I was playing with my pedals while audio streamed out of the DAW. Thanks so much folks! Got my eye on a color preamp next 😉
Super simple to assemble for a newbie like me
30 minutes to assemble.
Presto money saving, quality reamping. Tested it today. Very naaace
Our problem was sending a balanced stereo mix coming through a pair of XLRs into an unbalanced 1/8” stereo mic input to an A-V mixer. I had thrown together a custom Y-adapter to hook everything up. There was hum, but it was tolerable and there were constant complaints about overloads even with the console turned way down. One evening the hum became an issue, and we had to make it go away. I realized we needed re-amplifiers. Everything was really expensive and we needed two, so I took a chance on L2A kits. I hadn’t put together a kit since a Heathkit oscilloscope in the 70s, and these instructions are fabulous! The components were first class: 1% resistors, military grade pc board, Neutrik combo inputs. I’ve taken a number of DI boxes apart, and there’s nothing in them like this. I tested the box using pink noise from the console and monitoring with third octave spectrum. I had to use a mic input to get a decent level, so one big problem solved! I flipped the hi-lo filter switch and saw one end of the spectrum collapse and then the other end collapse, so the L2A was ready to put into service (actually two of them). I put them in the signal path with the volume control at 12:00. No hum! I also was able to send a nice juicy signal from the console to the A-V mixer without overload. These things have really saved our bacon.
This box is a killer value and it's great at what it is designed for. However, I use it for other level-matching tasks with line-level synths and effects pedals, to name just one. Highly recommended.
