Tubeset for Engl Fireball 100 (E635)
In the first position (V1), this tube set features our RT-7025 TAD REDBASE 7025/E83CC HIGHGRADE which is outstanding because of its high gain, but low microphony, powerful middles and a round, rich overtone sound.
The following pre-amp-positions 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 tubes, we recommend a quartet of our RT104 TAD 6L6GCM-STR REDBASE Premium Selected. The classic 6L6 sound! With the right amount of power in the low end, clear and transparent highs, they fill everything from big warm cleans to modern hard rock sounds with life and bite! This tube creates the sound of rock legends!
