Classic LA2A in your 500 series rack!
The IGS ONE LA 500 is an opto-compressor built for the 500 series format. This is the first high voltage vacuum tube 500 series module that is offered by IGS. It is powered with 250V DC from an on-board voltage converter, so it can be plugged into any 500 series rack equipped with a standard power supply.
Every single ONE LA is hand made with high quality, matched components (1% metal film resistors, Wima caps). It is equipped with JJ tubes and individually calibrated to give you the unique and unspoiled experience of one of the best opto-compressors in the history - the Teletronix '68 LA-2A. We have spent hundreds of hours designing the ONE LA, to make sure that it is as simple to use as it is versatile. Not only for harmonically rich vocals and strings, but also for huge and beefy drums and bass instruments.
Using two ONE LA 500 as a stereo pair will allow you to use it as an excellent bus compressor!
Three audio transformers (IGS Custom in an audio path and OEP in sidechain) have been used to provide excellent performance and with only two knobs and a single compressor/limiter switch, there is nothing that could go wrong. Additionally, you can replace the photocell easily (special version available)
"No compromise device - all tubes are powered by 250V DC!"

Opto compressors are said to sound very musical, especially when used with bass instruments and/or vocals. In my live rig, I’ve been using an opto compressor pedal for quite a while now, it makes my bass or guitar sound thick and warm, while preserving the punch of the instrument...
As I promised (see my first post on the topic), I’m going to reveal some secrets about my last mix project. It’s kind of a DIY music video, made for my youtube channel. It’s an acoustic ballad, played by Julia Motz and me on two guitars. If you like our music, check out www.motzundteissen.net.
When I first came across IGS products, I was immediately taken by the care and precision these units are built with. It shows the people at IGS take pride in their work and stand by their products. A while ago I had the opportunity to spend some studio-time with an IGS ONE, basically their take on the legendary LA-2A design.
