Interested in these has anybody seen or heard these they look pretty good and a great idea what does the focus button do ?
There's a review of this in the latest Guitarist magazine in the UK, together with the Dime distortion.
It may be on their website as well <http://www.guitarist.co.uk/>.
Cheers,
Sorry - although the review is in the magazine, it's not on the website (at least not yet).
The focus button turns on a preset scoop eq, cutting the mids and boosting the high and low frequencies. It can be used with either of the two distortion channels.
IIRC the reviewer's opinion was that one of the two channels sounded like an MXR Distortion+, while the second channel was higher gain.
The channel with high gain is the same circuit as MXR Dime, the distortion designed to Dimebag Darrell. The focus switch is a mid scoop.
