We put this kit together just for Blues players who want the Blues Option kit with the JJ EL844's! This is our Low Output Blues Option Retube Kit and it contains a matched quad of JJ EL844's to drop the output a couple decibels along with a standard ECC83S for V1, an ECC832 for V2 and a graded high current ECC83S for V3. This kit uses an ECC832 in V2. It cuts down the gain by about 40% in the drive channel but retains a nice crisp attack and warm tone.
