2026-GPX-JSA-Effects-LNS-Overdrive-OD-1-Main-700.jpg

I only discovered the existence of the LNS Overdrive pedal a day or two before the recent Leeds Pedal Show - which both I and JSA Effects were attending. I had read that Simon had managed to get his hands on 3 super rare original NOS RC3403 quad opamp chips - where his mods included really unique active Treble and Bass controls, along with improved / louder output.

 

I was determined to arrive at Leeds super early to be in with a chance of snagging one of these. In fact the other 2 had been ...

So what we have here is essentially Matt Webster’s 2 favourite overdrive / boost pedals - which were originall made by Simon of JSA Effects. These are modified editions of Tube Screamer and Klone circuits, and have been combined here for the first time in a singularly potent pedal.

This Treasure Chest is adjacent to the Sandman, while with the help of Marc from SoundLad ...
