Looking for sound....Custom Trains FM locomotive

Electric Railroad has new sound boards with FM diesel sounds. 

You can find their website here (www.electricrr.com/purchaseRailSnd.htm) and sound examples of that particular sound set here. (https://soundcloud.com/rrsounds/fm)

Note that your choice of loudspeaker and its enclosure will have a very significant effect on sound quality and overall volume.

Cheers,

I'm using the factory Custom Trains speaker in it's fuel tank enclosure, on my converted FM right now.  I tried a card stock baffle to increase sound, to no effect.

AFAIK, I've got the horn and engine sound volume up as loud as they go.

Since then, I've found out that the Sounder AC from MRC is now only available with two sound sets....MP15 and SD45.   MP15 would likely be the closest to what I need. Also checked out ERR, and their FM is the same as their EMD 567 sound, at least on the link I used.  This will be great when I sound up my Big Illinois Central F3 A-B-A set.   Might wind up using two different sets between the four units I have to convert.   FWIW, The MP15 sound would be quite close for an H16-44 / H16-66 effect.

Sorry but this is incorrect. I bought three of these and you still have the Alco sounds in them as well as the Sd70M.

That's better !   Probably a 1600 HP OP engine, not quite "beefy" enough for the big twelve banger Train Monster engine, but it will work.  FWIW, the info on the newest Sounder AC came right from the MRC customer rep. on Friday.  He also said that there are older units out there for people who want to track down distributors with the old four prime mover chip.
