mike ault tone prs 30 demo

[grupps]

Hiyas, Can anyone enlighten me as to the effects used for the tone he produced with the NF3 guitar through the prs30 amp. About the sweetest tone i ever heard. I guess a bit of delay, overdrive but I'm an acoustic player who has just put a downpayment on a p22 and would love to get close to that sound. Cheers
