7025-WB Highgrade Selected Matched tube pair TAD

The Tube Amp Doctor 7025WB Highgrade is tested and meticulously selected for the lowest noise and microphonics for use in the critical first preamp stages of High-Gain guitar amps where noise and microphonics could be an issue. The TAD 7025 WB Highgrade has a balanced tone with an little emphasis on the upper mid-range that gives a nice string attack and clarity to the sound while retaining a strong and defined bottom end. The 7025WB Highgrade will also do equally well in vintage guitar amplifiers.
 
If the 7025 WB is used in sensitive phono preamps the tube adds freshness to the signal without being harsh or spiky.
 
The TAD 7025 Highgrade can replace any ECC83, E83CC, ECC803S, 12AX7, 12AX7A, 12AX7M, SPAX7®, 12AX7WA/WB/WC/LPS/EH, 5751, 7025, CV492 and CV4004.
