TAD Tube Set for Mesa Boogie Express 5:25, and 5:25 Plus | Mesa Boogie Tube Sets

Tubeset for Mesa Boogie Express 5:25, and 5:25 Plus

 

The tubeset for the Mesa Boogie Express 5:25 uses our RT-7025 TAD REDBASE 7025/E83CC HIGHGRADE as input tube. Note that the Express uses the V2 position as input stage! This tube is outstanding because of its high gain, and yet low microphony, powerful middles and a round, rich overtone sound. Played clean, the TAD REDBASE 7025/E83CC delivers a warm, liquid tone which is very responsive to dynamic playing.

 

All the other preamp positions (V1, V3-V5) have our RT003 12AX7A/ECC83 TAD Premium Selected. This tube delivers very good gain, tight deep bass, fat mids and a silky top end with overall definition and brightness. It is selected with balanced systems and improves overall response. Best for clean tones, as well as for sounds requiring deep-bass power like any modern preamp.

 

For the power tube section, we chose a pair of our RT272 TAD-EL84-Cz with high-class cathode coating, plate options and gold grid wire, and therefore overall reliability. The sound is very harmonic in the middle and treble frequencies, without adding too much power to the bass. The result is the best EL84 in current production.

 

This combination will guarantee a maximum in gain and power, with very little noise, tight bass and silky highs.
