Double triode 12AX7A / ECC83 .
Selected TAD tube.
The TAD ECC83WB Selected was tested and selected for low noise and low microphony perfomrance.
The Tube Amp Doctor ECC83-WB Selected has a balanced tone with a slight emphasis on the upper mids,
which gives the sound a nice string attack and clarity, while maintaining a strong and defined bass range.
With the extra kick in the upper mid-range, the TAD ECC83-WB PREMIUM Selected also does really well in vintage guitar amplifiers.
If the TAD ECC83-WB PREMIUM Selected is used in hi-fi audio amplifiers,
the tube adds a bit of freshness and presence to the signal.
