Love the clean channel but you want to tame the Drive channel? After experimenting with these amps we found that using a JJ ECC823 in V1 will do just that! It leaves the clean channel as is and tames the Red channel down. An ECC823 for V1, two standard ECC83S’s for V2 and V3 along with a balanced ECC83S for V4. This kit contains a matched quad of JJ EL84's for the power section.
