Top Tone are regarded by afficiandos as one of the better companies when it comes to delivering the specialised tones that make Dave Gilmour's sound so appealing. This is the DG-2. It sits somewhere between the DG-1 and Light Drive as far as gain goes and it's just a pure pleasure to play.
I used a HIWATT SA212 Custom Combo for this video. There's also a Maxon AD999 delay in parts of it which will be obvious.
