We continue making America’s Favorite Brand of Digital Sound Decoder while we address the next crisis, the global shortage of electronic components and other manufacturing supplies. This affects all manufacturers and nobody knows when the pipeline of parts will become more stable. SoundTraxx will take all necessary steps to reduce the impact to our product deliveries.

On top of that, our products feature industry leading featues, top-knotch sounds and all of our decoders are made right here in the USA!

"By the way, after attempting to read the [other decoder] documentation, which is nearly impossible, with their small print and no logic for customers, I found all Soundtraxx Documentation exceptional and easy to follow. If for no other reason, that is the most compelling for me to have become a Soundtraxx customer for life!" -Chris

" Yes [I], have experienced 'Confused Decoder Syndrome' with all brands. So far have found the Soundtraxx Decoders to be the easiest and most logical to understand and adjust. They can be adjusted to how you want your Loco to run, not to how the Manufacturer thinks it should run. I use the Ops mode mostly as it gives immediate feedback on adjustments. Some Decoders limit the use of Ops mode. Many use computer programs to make CV changes but this can be more time consuming than a quick adjust in Ops mode. Like putting a car on a Dyno when you want to check the tire pressure." -Dennis

"I recently purchased an Athearn/Genesis Southern Pacific "Commute" GP9 with Tsunami2 sound.
I just wanted to say what a fine job you've done on the Tsunami2 line of decoders; with all the options available and the GREAT sound. I gotta lay out a budget plan to add to or upgrade several of my locomotives. I especially want Tsunami2s in my Steam locomotives for your DDE Sync feature." - Daniel C.
