I bought this speaker as an upgrade for a Laney Cub 12R in which the stock speaker wasn't up to the job. I have a Fender Hot Rod Deluxe which has also been modded with one of these speakers and the amp really sings. I use it primarily with pedal steel guitar in which I need it to remain clean whilst playing at relatively high volume. It does this really well. The Laney is a much smaller amp and, at 15 watts, is naturally going to break up a little earlier. However, since swapping in the Celestion V30, there is way more headroom available before the amp begins to show any signs of breaking up, providing a really good emulation of the clear highs and solid lows of a Fender amp. And even when this does occur, only the slightest bit of gorgeous saturation can be heard. It makes available a huge amount of volume to what would otherwise be a generally quiet amp. This is a great speaker.
