Acoustic Distortion Pedal?

I play my live gigs on my yamaha acoustic nylon string guitar. It has a very good pickup system build in and I was wondering which distortion pedal would sound any good with it?
I tried the Boss Over drive and metal zone pedals but I get to much feedback... any advice would be much appreciated
Thanks

Just came to mind that try equalize it down from 125, on some cases it reduce feedback, but not fail the sound too bad..

Find out what this guy has....

I have run my ovaion acoustic through a big muff pi.....sound fantaboulus

Wow, that was darn cool.. thanks for sharing m8, gotta find his albums

Yea john butler is good, check out his Ocean song. Been listening to this guy for years. . .

Little things: Location of amp...make sure it's far away and not pointed right at you.

Soundhole covers are made for this...but if your song has clean AND distortion it may not sound right for you.

I think a Rat type pedal might be a good choice, but I have never tried amplified nylon, so I'm just talking.

if you want a distortion and an acoustic sound check out the Bass Big Muff. it has a mode that will amplify your clean sound and the distortion, and you can level it out how you want

Thanks for the advice guys, I bought myself a Boss Me-20 multi effects pedal and im more than satisfied! thanks alot!
