Currently there aren't many high gain models available in the tone stack list.
- EVH 5150III 6L6
- EVH5150III 6L6 Stealth
- EVH 5150III EL34
I think there is big difference in the sound of the original Peavey EVH which is already in the current tone stack list with the new EVH - Fender distributed 5153 models.
While the EVHs have sound differences, the Brightcap and Tonestacks are the same.
