Tube Works preamps

What is the difference between the Blue Tube II and the Real Tube II preamps? Is one preferred over the other for steel guitar? Do they need to be modified to get a good steel sound?

The clean channel on the Blue Tube was typically modified for steel applications. I believe that the mod expanded the high frequency range.<FONT SIZE=1 COLOR="#8e236b"><p align=CENTER>[This message was edited by Kevin Hatton on 14 September 2002 at 10:40 AM.]</p></FONT>

I have a Blue Tube II Preamp RT-924 but only the B Out works (Line and Inst. out) The A
out does not work for some reason. It does not have the mod and I do not think it can have it. Do not know much about it. Will give someone a good deal on this unit if you are interested. This should probably be placed under Buy and Sell but inserted here since this is the subject. Thanks.

E-mail me, Bill. I've got another Blue Tube that needs work, I can use some parts. Thanks!

Does anyone know exactly what kind of modification is done on these units for steel guitar?

I can't tell you EXACTLY what it is, but the input stage of beefed up to handle the hotter input of a steel guitar pickup. Mine has a sticker on it saying "Steel Mod." Call Genz Benz (TubeWorks) in Arizona at 602-941-0705 for details. They may have discontinued this item as it's not on their current site. Try this:

I have one like Russell, with the same inscription on it, but can't find any use for it.

Here`S the answer I got from Scott Andres at Genz Benz.

-------------------

The steel mod increases the plate voltage of the tube on the clean channel so it can be played cleaner louder. There are also several other smaller adjustments to the gain structuring. We only do the steel mods here. The mod costs $100USD or you can order a new one with the mod already installed. Thank you for choosing Tube Works.
