..an Alessandro Black 'n' Tan :o
Very nice amp, if very overpriced compared to a 18w Marshall clone (or even a Tiny Terror). A nice complexity to the sound, very 3D tone. It had been installed with Power Scaling and I compared the Power Scaling with a THD Hot Plate.
While the Hot Plate sounded good, the Power Scaling sounded better. It was a bit clearer and more dynamic. The Hot Plate mushed things up a little bit and took away some of the character of the amp (replacing it with the character of the Hot Plate). This was at very low to medium settings. Above that, the Power Scaling had the advantage of being on a variable pot rather than stepped 4dB increments.
I'd been considering getting a Hot Plate but now I'm seriously tempted to have it added to my 100w Super Klipp. It really is a great way to tame the power of an amp, and it's cheaper than an attenuator...
