Its been two days since my zoom ac3 arrived. Here are my initial impressions...very easy to use , one doesnt even have to read the manual to get started. Great selection of effects which most guitarists need rather than having a 100 unusable ones. I particularly like the Pad effect for its atmospheric dreamy quality. The boost function is very useful for lead guitarists to cut through with their solos. Anti feedback switch works great, I just wish it wasnt so tiny/fiddly. It has really enhanced the sound of my Faith dreadnought. Looking forward to playing a lot of gigs with this baby! Special thanks to Eldon of Bajaao for the help in procuring the product.
