Want the smoothest richest tone you can get? This is our Gold Pin Option Retube Kit for the Blackstar Artisan 30 Heads and Combo Amps. It uses two Gold Pin ECC83S's, a Gold Pin EF806 to replace the EF86 and an EZ81 rectifier tube. The default power tubes are a matched quad of the JJ EL84's. With the Customize option you can configure this kit to use the JJ EL844's which will drop the power output a couple decibels (ideal for players wanting decreased headroom/output).
