SMH/BGB

[take em]

How does the big guys best call sound compared to the SMH, I've seen some in pictures and it looks like they use the SMH guts from what I've been told, and Jeff helped Mike Keller design it to I've been told, Thanks for the help.

i have both, started out with the BGB and yes the are almost the same call except for the outside and they use the same gut system. the only differance i see is the insert seems to be a little more flared only very little. mine has the old gut system (black) also as far as i know jeff and mike created these calls together.yes the sound is identical other than my BGB seem to be only a little louder than my other 3 SMH's but it might be the way i have it tuned.
