Want a really rich and smooth tone with less grit? This is our Gold Pin Option Retube Kit for the Budda Verbmaster 30 Combo Amps. It contains a matched quad of JJ EL84's for power, a JJ 5U4GB rectifier tube, one Gold Pin ECC81 to replace the 12AT7 and three Gold Pin ECC83S's one being current balanced for the phase inverter in V4. Just let us know in the comments section if you're looking for an early breakup, a moderate breakup or a later breakup for more headroom in which case we will choose the coolest grades we have available for the power tubes.
