Tungsten Preamp

From the vendor

Tungsten is a unique preamp and D.I. that is useful for both bass and guitar. It goes from warm clean to smooth breakup and everything in between. Unlike most D.I. units, it uses one of the triodes to produce the balanced output signal, so there is no transformer involved and it is a true “tube D.I.” unit.

Each PCB also includes two “12AX7-LEFT” PCBs for mounting the tube sockets and an XLR PCB for mounting the XLR jack and ground lift switch.
