I swapped the 12AX7 in my (BK Butler) Real Tube for a Philips 12AU7, and like the results very much. The gain "behaves" much nicer, and is easier to control. The distortion is a bit softer and sweeter than with the 12AX7. I have a couple comments to make on these pedals (incl. the Dean Markley Overlord). The power supply does seem to induce hum in these pedals, likely a design flaw. The AC cable also seems to induce hum in some of these pedals, especially where the cable meets the casing of the pedal. I have noticed that even bending the AC cable in certain directions can reduce or enhance hum.
Lastly, there seems to be a certain range of odd-order harmonics produced by these pedals which, IMO detract from the musicality of the device. These pedals where mass-produced with fairly cheap components, and while I love "cheap" tube pedal devices (I have had several), I am going to keep my eyes open for a Matchless Dirtbox or a Budda Phatman. I really have grown tired of searching for a cheap "holy grail" tube distortion pedal. If anyone has found one, please let me know!!!

I have one of these, the black pedal. I haven't really noticed a hum problem with a SFPR. Has anyone done any mods to these other than changing the tube? How does this pedal compare to the other tube/ss distortion pedals?

I had a 19" rack version of the Tube Driver by B.K.Butler. It did NOT have any AC hum at all.
I had it mounted with an ECC82, this is equal to a lower gain version of the 12ax7. I don't remember the correct name 12AU7 ot 12AT7.
DON'T get a Sovtek tube, you loose half the output. I did anyway. Cheap yugoslavian or Chinese tubes should work. Check Harmony Central reviews for this.

That is interesting! But not unusual, seeing that the rack version would provide more space for the components,as opposed to the compact nature of the pedal design!!!

I traced a B. K. Butler tube driver, the earliest, before the patent, and it did not have any hum at all as well. I really didn't like it at the time because it was extremely harsh but I think now, having read all these threads, that it may have been just because of the tube that was in it.

when i receive this pedal i think i will try a 5751 preamp tube--these cut the gain and are supposed to be very quiet and toneful tubes, a sort of tamed 12AX7. supposedly SRV used them in his BF amps. bill
