Many predator callers are looking for ways to locate coyotes by howling with open reed calls or tone boards. I have come up with a way to amplify these howling sounds with a minimal cost. The amplifiers can be made from empty plastic pop bottles. You will need to cut off the bottom end of these bottles, remove the labels, and after your testing you can paint the bottle with a flat black spray paint to cut down on glare.
The 20 ounce bottles shown above work great, but you may also want to try the two liter bottles for more volume.
You can experiment with the length of these bottles or funnel amplifiers.
Open reed tone boards or calls with a 7/8 inch OD (outside diameter) will fit right into the end of these bottles with the cap removed. I have also bored out some Schedule 40 PVC pipe with a 11/16 inch drill bit and cut these down to a 5/8 inch length. This allows me to fit my 5/8 inch OD tone boards into these cut/drilled down sections of PVC pipe for use with these same bottles. I prefer and have used the 7/8 inch tone boards for the past 30 years with my calling, but I have also made the 5/8 inch tone boards and some callers feel these are easier to blow.
The completed amplifier on the right hand side was made from a 20 ounce Dr. Pepper bottle with its straight neck taper, but Coke and Pepsi bottles work as well.
Bottles with constricted or recessed areas to the neck of the bottle should not be used, they cause a back pressure and distort the sound of your howls.
You can also purchase small plastic funnels for $1 to $4 at your local auto or farm supply store, WalMart or K-Mart stores and these funnels can be cut and modified for your amplifiers. The large ends can be cut down to a smaller diameter to fit your desires and the small tapered end can be cut down for a snug fit of your tone boards. The funnels can be painted with more desirable flat black color.

Yes I have used trombone and trumpet bells as well as buffalo and cow horns for my howling. With these modified bottles and funnels you can save yourself a few dollars and have the pride of of using an amplifier that you improvised for your own use.
If you would be interested in purchasing my 7/8 and 5/8 inch Dakota Coyote Howler tone boards, I will sell you one of either size tone board shipped TYD for $6 or two for $10. Payments can be made by cash, check, money order, or PayPal. If you are interested, please reply to this thread or send me an email. You can also use these tone boards without the amplifiers for the rabbit distress and coyote kiyi’s with your predator calling.
