Permalink Buying a Silver Face Fender Twin Reverb Modified for a 15 inch Speaker

The Custom 15 is nothing more than a 1x15 Twin Reverb. I'd buy a used Twin and stick a 15 in it.

Seriously uninformed here, but the 1X12 and 2X12 combo amps and cabs I've looked inside (an admittedly limited sample) don't have enough vertical clearance for a 15. Even Fender's Twin Reverb Custom 15 is over two inches taller than the standard Twin. Does a 15 really fit well in the standard Twin Reverb, and what other mods or adaptations, if any, are needed to do this swap? Thanks!

Hi Noel,

check out this post: Quad Reverb
You will need a different baffle (with a 15" cutout) and maybe have to take away some wood on the inside of the cab (not much), but it is definitely possible to fit a 15" into a 2x12" combo cab. Hope this helps. If you need more pics, please let me know.

Thanks, Kilian. It helps a lot. It also sounds like success depends on what 15 is used? What do you think of this speaker for this application?

And if anyone's panicking, NO, I'm not contemplating modifying my Music Man in any way!

Noel,

I am be stating the obvious, but that is Matt's speaker for sale. Why not ask Matt for his opinion? If you already have done so, just ignore me. Most folks do that without being told.

Norm, yes, it's Matt's speaker. I thought I didn't need it, but the "free" one didn't work well.

What's up is I MAY have access to a pre-driprail Silverface Fender Twin that someone put a Jensen 15 in. It's had a hard life and looks it, and the installation of the 15 is pretty poorly done. The guy who swapped speakers simply cut a large hole in-between the holes for the original 12's. About half the of the speaker isn't screwed to anything. But the amp sounds find, and the reverb and tremolo work. Same guy who used to own my Music Man. He's lightening his amp load. Literally.

If I can get it, it will be VERY, VERY cheap. Like not more than $250.00. Just have to make sure the smoke is in the wires, all the tubes light up and nothing expensive is busted. And, I was wondering if Matt's speaker would be better suited to a Bass VI than whatever is in this old thing. (Can't read the label from the picture and it's not in the store yet.)

I was going to talk to Matt, but Natalie JUST had their new baby (It's a boy!) and he's been very, very busy.

I'll be quoting Mr. Dale on this.

"Pre-Drip rail silverface twin" does not compute. The first silverface twins were the drip-edge models and the early ones were blackface circuits amps.

You will need an early twin if you are going to replace the baffle board to accept a 15" speaker. They screwed in place on BF and early SF amps and they are easy to change. The later 70s twins had glued in baffles and there is not much you can do with them short of having a new cab built.

I have built a couple of 15" twins in my day mostly for steel guitar. If I were to do it today I would find a SF twin chassis and mount the chassis in a head cab then get a cab for a single or 2-15 set up ala Dual Showman. It's a lot easier to haul around a head cab set up. This is important as I age, Ha!

I own a Dual Showman rig (AB763)and use a BF sized 2-15 cab with it for surf. The cab is loaded with Weber Neo 15".

Okay. I thought the drip rail came later. And there's already a 15 right in the middle of it. Definitely silverface, no drip rail (Isn't the drip rail the bright trim around the control panel?) , blue lettering, bright switch, tremolo, reverb and all. No drip rail. I don't have permission to post a picture. But it looks like this, but with the 15 instead. Does not have provision for casters.

Noel,

If the panel is the same on the one you are looking at, the amp would be 68-71. From 72 on, there is a master volume next to the pilot light.

Until I have a pic of the control panel in front of me, I can't say for sure. I was just trying to show cosmetics. I hope to get permission to post pics of the amp's control panel, wiring and speaker installation for your consideration and advice.

The drip edge Twin amps were called such as they have an aluminum molding around the grill. All of these have screwed in baffles. You really need to look in the back of the amp to see if there are blocks glued/stapled to the cab to which the baffle board is screw mounted.

By the time the master volume amps were released, I believe all were made with the glue in baffle boards. The speakers were also slightly offset in the cabinet, one higher than the other. Based on that fact and that the amp pictured is a non-master volume amp with a tail logo it, the amp pictured, very well may be a screw in baffle cab. Casters can be easily be added to any of these cabs.

These early SF Twins can be a real bargin in the marketplace. The only real exception would be a skinny wire '69. They kinda sucked. Any of these can be easily blackfaced. All you really need to do is convert the bias section and phase inverter and clip out a few caps.

Thanks! I hope to know a lot more about this amp tomorrow or over the next couple of days. The owner has to bring it in.

Noel, here's what I'd do:

  • Check if the amp is in a playable condition (tubes, caps, etc.)
  • buy it for 250.00 USD (bargain)
  • order a head from Beaver Bottoms
  • buy a 1x15 tone ring cab
  • order a Weber 15" speaker
  • don't look back and play like I've never played before Wink

I'm serious. If the amp is in a good condition you can't do anything wrong for 250.00 USD. I'd always go the head/cab way, as it is better to haul. Just my 2 cents.

I have a EV 15" in a seperate cab, and it sounds very good with a Dual Showman - not too boomy.

Caught a PA guy sneaking a look to see what it was at one outdoor gig - but it was louder than his PA!

I have to agree, Noel. As long as this is not a 1977 or later Silver Face then I think you will be happy.

Paul is very sure it's way earlier than '77. He's trying to determine if it's pre-70 or newer. This plan sounds like a great way to slowly, as affordable, upgrade the amp. Beaverbottoms can make the head cab first and the speaker cab later. According to Matt, his Sica Neodynium 15 sounds just like the JBL D140F he replaced it with. Would a Weber 15 (which one?) really be better for a Bass VI application than the Sica?

Also, the total amount is right up there with a lightly used Fender Twin Custom 15. Other than spreading out the cost over a year to put it together, is this actually better?

Honestly, I really wish Quilter would just come out with a 15-inch extension cab for my MicroPro-200. That would be perfect.

If this thing doesn't pan out, I was actually thinking along these lines using the 160 WATT Fender Stage 112SE. It has no collector value, is solid state which some say is happier playing bass (see several posts above) and accomplishes the same goals with less weight and better reliability.

It's a win for me either way, because I won't sell every amp I own to afford either the Quilter Steelair or Fender Twin 15.

Seems like a much simpler solution. Any 15" cab will work, doesn't have to be a Quilter. I use one all the time.

Thanks, Danny! What can you tell me about it? All I can find in 15's are ported bass or PA cabs.

You can buy a cabinet and put a 15" in yourself. Check craigslist for guitar speaker cabs or get a new one from JD Newell.. If you find a 12" speaker cab big enough to put a 15" into, have a friend who's handy with a jig saw make you a new baffle.
