I'm not trying to start any kind of debate here, or to get people riled up about whether certain caps or types of caps sound better. I know where those threads head and I know there's no real proof. In the next month or so I'm going to be house and couch bound due to a fourth back surgery so I'm looking at building a couple of pedals and maybe soldering up a board for a future amp project while I'm stuck wearing a brace. Based on the majority of the amps I've been inside of, it seems that the three caps for the tremolo oscillator almost always seem to be disc type of caps. Is there any specific reason for this or is it most likely that they were the least expensive caps available at the time? I know that my Gretsch/Supro is almost all disc caps due to cost, but I'm wondering if there is possibly something about them in a tremolo circuit that makes them desirable such as they start to oscillate easier or something along those lines. Just trying to decide if I should specifically look to buy those three caps as disc caps or use the same thing throughout the board. Thanks.
