12AX7 ( ECC83 ) TUNG-SOL Long Gray Plates Foil Dimpled Getter Matched Pair Tubes MADE IN USA '60

Sound Description:

The 12AX7 Tung-Sol Long Gray Plates , with foil getter and long gray plates , produced in the United States in 1960 , is a tube highly appreciated for its balanced, dynamic tone and excellent openness in the high range . This matched pair represents an excellent example of the most refined American production, capable of combining musicality and technical precision , with a low background noise and a very coherent behavior even in high gain stages.

Bass: Solidly anchored and defined, with good articulation and control. Never intrusive, but with the right presence to support the entire sound message.

Mids: Clean, clear and slightly open. Vocals and solo instruments emerge naturally and without excessive coloration, offering a good balance between neutrality and musicality.

Highs: Airy and well extended, with a touch of brightness that gives definition to the scene without ever becoming harsh. The high range is particularly pleasant on neutral or slightly warm systems.

Dynamics: Quick and articulated, with a fast and fluid transient response. Listening is always engaging and realistic, even at low volume.

Soundstage: Wide and coherent, with good depth and stable imaging. Instruments are well separated and placed, contributing to a tidy and precise soundstage.

The 12AX7 Tung-Sol Long Gray Plates is an excellent choice for those looking for a precise, transparent but never cold tube, ideal for both hi-fi applications such as line and phono stages , and for guitar amplifiers where definition, headroom and great sonic articulation are desired.

🎸 Use in Guitar and Bass Amplifiers

The 12AX7 Tung-Sol Long Gray Plates is a tube highly appreciated by musicians for its fast dynamic response , definition in the midrange and transparency in the high range . In the guitar field, it offers a clear, articulate and musically balanced sound, making it ideal for those who want to maintain tonal precision even in saturated contexts.

🔊 Ideal for musicians looking for:
✅ Clean, bright but stable, with quick attack and good separation between notes
✅ Responsive and defined overdrive, without excessive compression or muddying
✅ Touch-sensitive dynamics, great for those who use the guitar as an expressive instrument
✅ Generous headroom, useful in contexts with articulated pedals or dynamic effects

Examples of amplifiers where it performs very well:
🎸 Fender Deluxe Reverb / Twin Reverb – Clear tone, with presence and articulation perfect for clean and blues crunch
🎸 Marshall Plexi / JCM800 – In the early preamp stages it offers definition and reduces excessive compression
🎸 Vox AC30 Top Boost – Maintains the typical Vox brightness without hardening the sound
🎸 Mesa/Boogie Mark Series – Increases clarity in clean and lead channels, especially in complex setups
🎸 Ampeg V4 / SVT – On bass amp ensures punch, precision and headroom even with active pickups

🎯 Note for rock, funk and blues guitarists:
This tube is ideal for those who want a punchy, open and always under control sound , even with distortion. Less suitable for those looking for a “fat” and colored saturation: in that case, you can prefer tubes such as RCA or Mullard Black Plates for greater harmonic euphony.
