Re: What is the most aggressive, pissed off sounding amp you can think of?
For real world amps, I'd have to say one of the Recto's or a H&K Triamp.
For mucking about and getting weird tones, the super-pissed title has to go to an old Silvertone I picked up at a garage sale. It's got a single 6v6 driving a 6" speaker, but when being pushed by an EMG 85 w/ a PA-2 boost, nothing can tough that tone. It's fizzy, spitty, and fuzzy in a cool lo-fi way. It doesn't sound big by any stretch, and I don't imagine using that tone very often, but it doesn't get much meaner than that little amp being driven hard.
