    I was supposed to receive this item on 5/12/25, per USPS tracking which showed that it went out for delivery. I never received it. USPS searched but were unable to tell me what happened to the item. If someone else received it, they never returned it to USPS. After I contacted this seller, they immediately send me out a replacement at no further cost to me. I received it just moments ago. Super fast shipping. Terrific customer satisfaction. Thank you.

    Aside from the box being full of large black ants(palmetto bugs down in the south) everything was perfect. The decoder was sealed in a separate bag so nothing in with it! It functions perfectly and sounds amazing in the SD60!

    Soundtraxx Economi decoder review

    This is an excellent choice of sound decoders if you are interested in buying one. It is simple in design, inexpensive and has very excellent sounds. I like it because it has 5 different prime mover sounds that can be programmed by a simple CV change and a grade crossing signal activated by a function button on your DCC controler. All air horns (or steam whistles) sound so much better than the 1st generation of Tsunami decoders and so do the bells and air compressors. For the price, these are are a great value. I highly recommend this product.

    Not every HO scale Diesel Locomotive should be run with Sound! Keep it simple!

    The Soundtrax 882004 decorder diagram has 4 optional Diesel body side marker lights 1.5voltage contact points to supply power from. As well as the normal front/rear +/- headlight power contact points for 12–14-volt Light Bulbs. Sadly, the additional Marker Lights after careful soldering of each, did not Light Up! The Diesel sound choices worked fine. My ATLAS HO FM H15-44 featured front & rear side marker lights which turn red or green with the change of direction. Please note that this Decoder is specifically for ALCO 244 or EMD 567-710 motive power sounds.

    A high performance sound decoder.

    The Soundtraxx Economi Eco-PNP Diesel decoder is the best sound you can get and at a very reasonable price. When hooked up to a one or two watt baffled speaker, you will be amazed at how much sound it can produce. The motor control is exceptional and programming options are easy to understand and use. Unlike other most other manufacturers, Soundtraxx customer support is easy to find.

    Typical Soundtraxx excellence

    A very good value for converting older Tsunami decoders to the newer generation features and power handling. A few features shy of the top of the line Tsunami 2 but inconsequential for my secondary train consists.

    Great DCC sound decoder

    Used these DCC sound decoders to replace ESU decoders that failed to perform properly and eventually failed. Soundtraxx has ALWAYS performed beautifully and are easy to install and custom program. I absolutely love these decoders and wood recommend them for anyone desiring excellent motor control, great lighting options and SUPERB sound!
