Want all the gain you can get? This is our High Gain Option Retube Kit for the Epiphone Galaxie 10 Combo Amps. It uses a single handpicked High Gain ECC83S for the front end and the default power tube is a single JJ 6L6GC. With the Customize option you can configure this kit to use a JJ 5881 or a JJ 6V6S which will drop the power output a couple decibels (ideal for players wanting decreased headroom/output).
