Want a really smooth and rich tone with less grit? This is our Gold Pin Option Retube Kit for the Bad Cat Cub III 30 Heads and Combo Amps. It uses three Gold Pin ECC83S's with one being current balanced for the phase inverter, a Gold Pin EF806 to replace the EF86 in V1 and a GZ34 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).
