Biker, I assume your finding it hard to replicate a bugle by way of using a diaphram call with or without a tube. I haven't heard of anything in the same fashion as a squeeze call for a bugle, however I know many who find the Hyper Lip Bugle by Primos to be a decent bugle to use. I am sure their are others as well, that I haven't tried or used. Right now I am using the Primos "Terminator" Bugle, it takes a little bit of practice for lip placement and pressure but with sometime should be manageable. I would suggest whatever bugle you buy get a video or audio tape for instructions and usage of that product. Then Practice, Practice and Practice some more.
