Frans,

I agree, Yamaha sounds are not as natural as PA500 in my ears too.

I hope someone with experience with both M50 and PA500 gives us more information, since it looks guitar sounds are not the same on PA500 and M50.

I have ordered extended warranty too (well a cheap one, so I hope it is useful) so I think I can use the pitch bender with ease of mind.

Thanks again.
