Question re Webb 6-14E

Erv Niehaus · Post by **Erv Niehaus** » 31 May 2011 11:33 am

On the back side, upper right, on the Webb amp I recently received there seems to be an extra jack.
It is located to the left of the "remote reverb" and the "preamp out" jack.
Does anybody know its purpose?
Thanks

Hi Erv,

I don't think that was there from the beginning. It may be a Power Amp In jack that was added by someone to provide an effects loop. I had that done to one of my previous Webb amps like yours and it worked great.

Lynn,
Thanks!
On the lower right front corner of the amp it says "custom". Does that mean that something might have been added to the amp?

Mine is s/n 969 and it does not have that jack.

My Webb amp came with a reverb control which can be attached to the leg of your steel guitar and I believe plugs in there, although I never used it.

I believe they all have remote reverbs and they all have that "Custom" insignia.

I would also suspect a power amp input jack. To test that just plug a short guitar cord into it. It should cut off the preamp signal and also make a bit of noise when you touch the end of the guitar cable, as you would be connected to the power amp's input.

If that's not it then it is hard to tell without looking inside to analyze what was done

Thanks, guys!

Erv, it was not part of the original Webb design. Mine is #749 (1978) and does not have that input, and is clearly labeled "remote reverb" and "line out". I suspect it is a power amp in effects loop as suggested. In early 2000 or so, I recall Jim Webb stating this could be added to the older versions.

The "custom" logo on the bottom right corner of the amp was part of the early models and was discontinued in the early/mid 80's for whatever reason. Other than it being a "handbuilt" amp I don't believe it differentiated any specific features.

My GP 6-14 does not have the "custom" label. It does have the power amp in jack/pre amp out jacks, also labeled as effects send/return respectively. This amp is from the mid 90's.

Erv, My Webb is # 80053 (last one made) and it has that input and it is labeled "Power Amp In".

Darrell,
Thanks!

my Webb amp has a 4ohm JBL K130 speaker as its main, is it ok to add another 4ohm speaker as an extension speaker? or would this damage my amp?

Erv Niehaus · Post by **Erv Niehaus** » 8 Jun 2011 7:36 am

On the back of the amp it says 2-4-8 ohm for speakers.
The way I understand it, two 4 ohm speakers hooked together makes for 2 ohms.
It might be ok but I really don't think it's advisable.
I'm looking for a couple of 8 ohm JBL speakers to hook together to come up with 4 ohm.

Kevin Mincke · Post by **Kevin Mincke** » 8 Jun 2011 7:45 am

I'm with Erv, and even though that's what it says on the back, I wouldn't put a 2 ohm load on my Webb(s) and continue to run it that way. That's starting to tap it I think!

Actually that is half correct. When speakers are connected in parallel ohms go down as described above. When speakers are connected in series, ohms increase (ie: two 4 ohm speakers connected in series create an 8 ohm load). The issue is how your extension speaker is wired.
