This is our Gold Pin Tweed Retube Kit for the VOX AC4C1. This option offers the same gain reduction as the standard Tweed kit while retaining a more open and chimey overall sound. If you're looking for a rounder tone stick with the normal Tweed option. This kits contains a single JJ EL84 for power along with a Gold Pin 12AY7 for V1 and a Gold Pin ECC83S's for V2 in the preamp. Let us know in the comments section if you're looking for an early breakup, a moderate breakup (default), or a later breakup for more headroom in which case we will choose the coolest grades we have available for the power tubes.
