you should check this video at the beginning :Plus reduced negative feedback.
To be clear I don't know anything about what Eddie really used or didn't other than not to trust a word he said, but my ears are not hearing any extra gain amp modifications in those tones.
Ossie is the only one being able to recreate the spiting cough speaker sound. Just listen to the little guitars intro riff. He explains the josé mods and so on. I'm gonna try those mods. His sound is perhaps the closest VH tone with the one of david bray amps.
