Gary, I have the real tube II but it's an older model I think they rebuilt it just to make it look more modern but I don't know if the guts are still the same. I love mine and would consider it audiophile grade. Very quiet, clean, warm, versatile and more. The best features are the stereo effects loop and dry out for recording and reamping.Bob |

What is the difference between the Real tube and the Blue Tube units ?
I recall trying a Blue Tube floorr pedal with a bass rig years ago but had to return it . A knob was damaged in shipping by MF and it sounded very nasal in mids |

I really don't know the difference between the Real Tube and the Blue Tube other than the Blue Tube is sposed to give you a "warmer" sound. Tube Works would put a steel mod on a Blue Tube and I have a Real Tube with a steel mod on it. |

I don't remember the different model designations. However, I had one of the older models and called Genz Benz about getting the steel mod installed. They refused to do it because they claimed they didn't get all the documentation when they bought the MosValve/Blue Tube line. They said they only model they would install the Steel Mod in was the final version that they (Genz Benz) built, as they had the complete documentation for that model. In discussing some of the shortfalls of this preamp with the tech he admitted that the power supply design (location of components on the printed circuit board) was a problem area on the preamp. The power supply components (and AC voltage) is adjacent to the bass and treble tone controls for the second (clean) channel on the preamp and if the bass is turned up you can (and he says "will") get some AC hum. The AC hum was too much for me, on the model I had, so I sold it to a lead guitar player who didn't need that much lows and he's happy with it. The fact it needed a redesign, to eliminate the hum potential, and small sales probably led to the reason Genz Benz quit making them. |

I don't remember having much of a hum problem but, for something different, I replaced my Blue Tube II with an Evans HVRP preamp. That sucker has enough knobs on it to keep me busy for a loooooooooooooong time!  |

Hey Jack, that's interesting about the power on the circut board. I never have my low's turned up over 5 and no ac hum but you can bet I'll try it tonight and see if I can make mine hum or if that only applied to your particular model. If I can make it hum I might try to make it learn the actual words next week! Edit: After all of the confusion on different models I went out to the studio and read the model number off of my preamp it's actually named Butler Real Tube II model no. 922 it's black with yellow writing. So all of my input on this thread may not pertain to your model sorry. Bob[This message was edited by Bob Martin on 29 July 2006 at 02:58 PM.] |

Bob, that's the model I had, too and it matched the MosValve 500 power amp that I still have. The problem is in the "clean" channel and AC power and power supply components are on the PC circuit board directly next to the Bass tone control pot and with low level audio there can be some AC hum induced through the Bass pot. I had considered trying to modify or redesign the power supply section but decided not to screw with it. With steel the bass needs to be way up and consequently the hum is more apparent. The "lead" channel doesn't have that issue. |

I had a #922 also..Didn't seem to have a AC hum, but the pots were often scratchy and had white noise hiss when you cranked up..Not a problem on stage, noisy at home...Nice tone ,though!!JS |
