Want a very smooth and rich tone with less grit? This is the Gold Pin Option Retube kit for the Crate VC30 thru VC50 Heads and Combo amps. It contains a matched quad of JJ EL84's for power along with four Gold Pin ECC83S's with one being current balanced for the phase inverter in V4.
Just let us know in the comments section if your looking for max headroom, moderate or an early breakup so we can select a proper grade for the power tubes.
