Mahalo Everyone!
I am seriously thinking about adding a ext/speaker cabinet to my 70's
Fender Deluxe Reverb for various reasons. Have any of you done
anything like this and were you happy or unhappy with the results. Any
help or opinions would be greatly appreciated.
Thanks
The Hodaddy
I just bought a reissue Deluxe Reverb - the guy selling it threw in a
new-looking fender cabinet with one 12" for another $50. Don't know
what brand of speaker is in it. This combo is mostly used by our
rhythym guitar player. When the external cabinet is added to the
Deluxe the sound becomes fuller and has a little less "edge" than the
Deluxe alone. Much better, fuller, cleaner sound for the rhythym
guitar. Haven't had much experience with the combo to say how if would
sound for lead guitar, but seems to lack "presence" and I think my
impression is I prefer the amp speaker alone for lead. Casey

yes try extension cabs! you might even like the sound of a closed back
or ported cab alone better than your current set up (just use the amp
as a "head")
For my taste, speaker distortion and surf don't mix - it's hard to beat
JBL's, they offer high efficiency and clear tone. Reconed K120's are
not that expensive and sound great. It seems to me most on the group
here regard the Showman as the holy grail of surf amps, and the JBL's
are a critcal part of the Showman sound. A Deluxe Reverb feeding one
12" JBL in a closed or ported cabinet, with the speaker in the amp
unused would result in a mini-Showman and I think an awesome "low
volume" (relatively) surf rig.
there can be some impedance matching issues (and phasing is critical
with mulitple speakers and cabs), but in general, use your ears and go
with what sounds best to you

Unless you want to incur the expense of a blown transformer and possibly worse,
unless they are both 16 Ohm speakers, never plug both internal and extension
speakers both in at the same time on the Deluxe Reverb. This is an 8 Ohm amp,
period.
That means one 8 Ohm speaker is all this amp is designed to handle. You can buy
a pair of 16-Ohm speakers and wire them in parallel to arrive at 8 Ohms, or a
pair of 4 Ohm speakers wired in series will have the same effect. Check the
ohmage of the speaker in the cab to be sure you won't be courting trouble in
using it with your Deluxe.
Years ago, a friend had just purchased a brand new Deluxe Reverb with money he
saved over almost a year. He was in a band, and another friend suggested that
for more volume from the Deluxe, he plug in an extension cab as well as use the
inboard speaker. Needless to say, the worst happened, right in the middle of a
gig, and he ended up spending almost half the price of the amp in repairs.

Bruce, thanks for the tip! We are using the Deluxe Reverb for the 1st
time outside tomorrow and I had planned on using both speakers. Now I
know to only use one or the other. Guess it seemed to do OK because of
the low volume settings we were using for practice. Casey

Casey,
The main point is that the total speaker load should always be at or extremely
near 8 ohms. You can use more than one speaker, but be sure that if you do, the
wiring of the speakers will result in that combined 8 ohm load.
Two 4-ohm speakers wired in series = 8 ohm load
Two 16-ohm speakers wired in parallel = 8 ohm load
You could replace the inboard speaker with a 16-ohm, and install a 16-ohm
speaker in the cab. This way, using both speakers, you'd have that 8-ohm
combined load, but you would always have to use the amp with both inboard and
extension speaker, which could have its disadvantages too.
If I'm not mistaken, Hammond makes a variable transformer, and you could modify
the amp if you wanted. Our resident amp wiriing expert, Loyd Davis, modded one
of my Vibrolux Reverbs, and added a rheostat to the back panel, allowing me to
adjust the transformer's ohmage from 2-4-8, allowing quite a range of different
speaker config's. If you don't mind altering your reissue amp, this could make
your life a bit easier in using the amp with different speaker config's when it
suited you.

Bruce - with all due respect:
I believe if you research the issue you will find that most techs will
agree that an impedance mismatch of up to 2X in either direction can
easily be tolerated by most Fender Amps. Even though it's always best
to match impedances there are some players that actually prefer the
sound of a mismatch. A mismatch will occur if 2 power tubes are
removed on a 4 power tube amp. If a Deluxe Reverb blew up feeding a 4
ohm or 16 ohm load, I would guess there were other factors involved.
The amps to be extra careful on are the 2 ohm amps with 4 - 10" speakers
Gerald Weber has discussed this issue extensively in many Vintage
Guitar issues.

P.S. and please check for phasing - it has a huge effect.
Bruce, thanks again for the clear explanation. Guess I never really
got it down when we studied electrical currents etc. in physics.
Anyway, will probably just leave the amp as it is and use the external
cabinet as the only speaker when we play out - it's does have a better
sound for the rhythm guitar, I think.

Well Bob - Likewise with all due respect, one of my specialties as a collector
is old Fender Deluxe amps. I've had several of them refurbished by a veteran
amp tech, Steve Dickun, "The Rock & Roll Doctor", whose prior background
included being the on-tour amp and guitar tech who travelled for two years with
AC/DC, and for another couple of years with ZZ Top.
I asked Steve about this, and he said, "I don't know what Fender was thinking,
putting the extension speaker jack in the back panel of the Deluxe without a
warning about staying close to the 8 ohm load rating. They didn't put any
warnings in the owner's manuals either. Easily 25% of the repair work I do here
is based on damage done by players using speaker loads the amps weren't designed
to carry."
Incidentally, Steve's favorite personal studio amp is the Fender Deluxe. He
owns Deluxes in Tweed, Brown, and Black-face, so again, with all due respect,
I'll stick with his advice.
In our band, Loyd Davis, former Surf Raider, has been wiring up, repairing and
servicing tube amps for over 40 years. His own policy is to avoid deviation
from manufacturers ohmage ratings, and with the years and kind of experience
he's had, likewise, with all due respect, I defer to his recommendations.

I also have a '66 Super Reverb - how do the ohms come out on that with
the 4 x 10' speaker setup? Not knowing enough to be concerned about
all of this in the past, I can say I've probably tried every
combination possible with my 3 amps, a '66 princeton reverb, reissue
deluxe reverb, and '66 super reverb - that is playing any one of the
amps through any of the other amp's speaker(s), alone or in combo with
the powered amp's own internal speaker(s), just to see what it
sounded like. This didn't seem to cause any problems - maybe because
it was only done for a few minutes at low volumes. I will be more
careful in the future! My new reissue Deluxe does say "8 ohm total" on
the back by the external jack but thats about it as far as advice from
fender - it does seem like they could address this in the manual. What
is a practical way to check for proper phasing?
Thanks, Casey

Casey - your question is answered in great detail in the current
(July) issue of Vintage Guitar - if you can't get a copy, email me
and I'll scan it for you. as far as phasing, you can put a 1.5 volt
battery and watch the speaker cone to see which direction it moves -
the idea is to get all the cones moving in and out in unison. I
usually check phasing by ear since my speakers are ususaly mounted in
a cabinet and it's more difficult see the cones. speakers that are
in phase will have more bass than speakers that are out of phase.
