EL84-CZ - TUBE AMP DOCTOR
EL84-CZ (Matched Quad).
BIG TONE, VERY DYNAMIC AND EXTRA POWERFUL BASS RESPONSE
The TAD EL84-CZ is the powerhouse and roughneck among the EL84s and provides most amps with an extra powerful bass response. You have to be careful with amps that already have a fat bass and you need to ensure that your speaker can handle the increased bottom end – it may just be too much. The EL84-CZ is the most powerful EL84 tube we ever heard. It has a big tone and is very dynamic. Our recommendation, if a powerful tone is what you are looking for.
