SoundTraxx Customer Comments:

"Your products and the support you provide are top-notch. I have several Athearn locos with factory-installed Tsunami decoders and they operate without a hitch. It is great to have an American company manufacturing and distributing a top-quality product."

"This order will be my first attempt at an installation, but I feel confident given the support literature and videos provided on your website. Also, Kudos to George Bogatiuk for the great job he does with customer support."

"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.
