"...BK Butler Tube Driver
The Tube Driver has a classic Marshall character, similar to the JTM and JCM. The tube makes a huge difference compared to most other overdrives, adding a unique warmth, compression and dynamics. Like the Powerboost, this one demands a loud tube amp. Not a lot of headroom, although lower gain settings allows a nice, crunchy clean boost. The current 2006 model also has a bit more top and gain, compared to older models, such as the Chandler. Using different tubes, like a
12AU7, can change the gain structure dramatically and add lots more headroom and warmth.
Bedroom setups: 6/10
Gilmour tones: Delicate/PULSE/Gdansk

Having trouble using the Tube Driver with your bedroom setup? Try Eric Johnson’s settings! The active tone controls makes the Tube Driver very bright and aggressive, but roll them all the way down, like Eric does, and increase the gain for aTube Screamer-ish overdrive with lots of compression and midrange! ..."
Вопрос, стоит ли заморачиваться с заменой лампы 12AX7A на 12AU7? Где и какую лампу лучше прикупить что бы звучала поприкольнее?
