Fender® TBP-1 Tube Set

Tube Set for Fender® TBP-1 tube bass preamp. Our tube set is meant as an upgrade to factory tubes. If you want an even fuller tone, a pair of Mullard 12AX7 will also work very well.

Replacing the tubes in TBP-1 is very easy. The two 12AX7 TungSol tubes go into the shielded sockets to the left of the preamp.
