2. EF92 Family
The EF92 family tends towards a more neutral sound with an emphasis on great vocal presentation, but the sound quality can vary wildly between different manufacturers. This is the only family of driver tubes that can be used on the older (out of production) LDII+ and LDII++ models (see List of LD Amps).
