Small box, Big noise.Review by T.E.
Bought one a few weeks ago and have now had chance to use it at practice/gig volume.
Very impressed with it, so simple to use, great variety of tone on tap, and having now had chance to turn it up a bit, volume in abundance and that was through my 8ohm cab so only just over half the available power.
It may look a bit odd when compared to some of the latest flashy class D offerings but this head is worthy of anyones consideration.
Simple effective and extremely portable. (Posted on 09/01/2017)
