Hi,
I was wondering which channel on the Fender Custom Vibrolux (the one with the white knobs) would give you more clean headroom, Normal or Vibrato?
Thanks!
Joe

Joe. I have a Fender Vibrolux Custom. the vibrato works on both channels, BTW.
the Vibrolux is such a nice amp, I think both channels will give you what you want.
Normal is merely 'darker' sounding.
both channels seem to break up at the around the same point.

What accounts for "dark"

less gain?

I always ass-u-me'd that Normal was a little cleaner...

Vibroluxs are a pretty clean sounding amp. two channels, one labeled normal. when I say dark it sounds like it; the high end is rolled off and the low and mid range feels pronounced.
the other channel has a bit more sparkle. or brightness.

again I have to edit. it is very true the reissues are different from the originals. my reissue has enough headroom for me. that is me. I have learned from past posts that this amp is not as clean for steelers. most of the time I play at low volume levels. it performs quite clean. at about five it begins to have character, in that it can break up. to my ears it gives the guitar a bit more guts. but not into the high gain realm or distortion.

if you want a really clean amp with tons of headroom, this perhaps is not what you want.

Brian.. Dark in steel language means not quite as much treble, more bassy sounding. (Edited) Sorry, the question had already been answered.

The Custom Vibrolux is not the same amp as a Vibrolux or Vibrolux Reverb. It's a higher-gain, modernized amp with a much more "edgy" sound to it. As far as which channel has more headroom, there's no discernable difference - one is just brighter than the other. In BF/SF Fenders, the "Normal" channel has more headroom as it lacks the extra gain stage of the reverb channel (the "Custom" has reverb on both channels).

I haven't found the Custom version to be much of a clean-tone amp...and in 6-string circles the vintage Vibrolux Reverbs are known for early breakup, not for their headroom. Nice sounding for smaller gigs or practice, though.

I'm using a 72 Deluxe for small places (most places!)

...Sometimes a 67 Vibrolux

always seems like I can squeeze little bit more headroom on the Normal side using a 72 6139 ShoBud

Thanks for the info. I am trying to crack the age-old problem of playing tele and steel with just one amp without breaking my back bringing the twin and without a mess of cords from the Pod.

Looks like you can't get there from here, eh?

Regards,
Joe

It's tough, because to get an amp to "bloom" properly you have to be able to crank it up, and with steel then you need to make bias and/or tube changes to clean up the sound. You *might* be able to get away with it to a point with 1) a cranked amp and low bias setting, and 2) a good overdrive pedal *always* on with the Tele for a more guitar-friendly sound (just a touch of overdrive, controllable with the guitar's volume control), plus another overdrive for "dirt" tones. It's a real balancing act, though; if you know tube amps really well you can do it, but trying to get a tech to make the adjustments is almost impossible, as he won't hear what you're hearing...

CVR's are quite "hissy", partially because they lack a negative feedback loop. They do break up fairly quickly. OTOH, I think they have the best tremolo on the planet!

For a light-weight steel/guitar rig, I recommend a '65 Deluxe Reverb RI. Immediately perform the following mods:

1. Clip out the bright cap on the vibrato channel
2. Replace the speaker with something very high efficiency (I currently use an Emi Cannabis Rex.)
3. Replace the rectifier tube with a Weber Copper Cap

And finally, use a preamp pedal with the PSG that will allow you to reduce volume, something like the Xotic RC Booster, or the Barber Tone Press. The idea is to try to let the input of the amp see the same amount of gain from both guitars, so you don't overdrive the input stage with the overwound steel pickup.

From an electronics point-of-view, the "Custom" Vibrolux Reverb is almost identical to the discontinued reissue brownface 2x10" Vibroverb. The circuit boards of the two amps are very similar (or even identical) so it is quite easy (if you're handy with electronics) to convert one model to the other. Schematics and layouts for both amps are available on the Internet.

I use one of these reissue Vibroverbs for my D-10 steel and it's quite useful for smaller gigs. It has more headroom than the CVR and is also much less noisy. I've installed a pair of Weber 10" California speakers to get a better low-frequency response.
