Feedback buster

[jimbyrne777]

Hi,
I gig twice a week with an acoustic duo and currently use a Gibson J200 backed up by a hummingbird/Sheryl Crow sig (yes got the Gibson bug bad...people either do or don't lol, there isn't any inbetween with Gibson acoustics it seems) However I have just purchased an Avalon L25 to compliment it live but am worried about feedback (venues and volume we play at we always sufer without using busters) as the soundhole is a touch too big for a std feedback buster. I may have to get a custom fit lutehole but before I spend ££££'s on that product I was wondering what others did to combat feedback, Is there anything out there like a feedback buster big enough for an Avalon/Lowden soundhole?
Thanks
Jim

I use a Lutehole with my A201CE and looks and works fine
