Sometimes we wonder if there is a limit of high end… apparently for tube producer from Asia, there is no limit yet!

This new custom version KT88-Z CB cobalt blue Super Tube seems have “surpassed the current high end KT88 tube offerings, in instrument separation and frequency extension on both ends”, according to factory in-house comparison to competition.

Order yours now to experience the new limit of ‘high end’…. KT88 doesn’t have to be low resolution as some people perceived!
