Since many years I have this awesome 1948 Gibson L7 non-cutaway. Now I want to have a DeArmond 1100 Rhythm Chief installed.
My first question concerns the positioning of the pickup. I noticed a lot of the DA p.u.'s are mounted to the neck as close as possible, others some inches lower.
On the net I found a DeArmond installation & operation manual (Rowe Industries) from way back ... The manual states:
'To determine location of microphone (=p.u.), depress 1st string to lowest playing position on finger board and move microphone as close to finger board as possible, or until clearance between string and top of microphone measures approximately 1/16". It is important that this 1/16" clearance be maintained so that maximum output may be obtained. Microphone may be moved closer to bridge for different tone timbres'
Any experience, advise that would help?
and
'The lateral location of the microphone in relation to the strings is essential. To assure a balanced pickup of each string the model identification marking, on the cover insert, should be directly beneath the 1st (E) string'
I don't see any identification marking on the DA 1100! So should the adjustable poles/screws be used to determinate the lateral location?
'Of course' the short neck rod is missing and I need it! I know Kokomo Music sells new ones at $35. What do you think is this a fair price or a lot of bones for such a small piece of hardware? Any (other) suggestions?

Here's a suggestion . . . "if you can't swim, stay out of the high water".
You have two of the finer components for jazz guitar ever made . . an L7 and an 1100 Rhythm Chief pup. Now is not the time to be thinking DYI. Take those components to a competent guitar tech or luthier . . . but, choose one with a good reputation of arch top knowledge.
-
First, forget about Kokomo Music, they have been closed for years...
Then, if you want to have the short rod and do not know what you are doing, by all means have someone competent do it.
What you could do yourself, is get the long rod, which is temporary, does not involve drilling holes (like the short rod does), and with which you can move the pickup up or down.
Here is my DeArmond FHC-B. Different pickup than the Rhythm Chief, but same system.

Thanks guys, I started playing guitar way back in the very early 60's. Never ever did some of the tech stuff myself. I stick to my own things. So no way I'm gonna do this job myself. just try to gather some knowledge / experience
-
Nice photo of your archtop Eddie ! thanks for the info. I'll have a luthier do the job with a neck rod (if I can find one) Just want to know a bit more about it myself
-
I installed an 1100 on my '47 L-5 not long ago. I did the entire job myself and, in spite of the odds, it turned out flawlessly. After spending an insane amount of $ on the pickup, I was keenly aware of how careful and meticulous I needed to be. I can offer advice but at the moment I'm not able to write for long.
-
Just to be nitpicking, I think the Rhythm Chief was model 1000, whereas the model 1100 was called Super Chief ;-)
Henk what type of control box do you have with the pickup ? Would you want to mount that on the pickguard too ?
If you need rods ask Mitch this is the email address MS64RED.EBAY at COMCAST.NET
-
Model 1000 was the Rhythm Chief, and 1100 was the Adjustable Rhythm Chief. There was no Super Chief AFAIK. I recently read a whole thread on this naming topic on another forum. Someone posted a photo of an original 1100 box.
Also, I got my neck rod from Mitch too... But only under duress. It seems he has some difficulty with his hands (health issues), and finds them very hard to make. I traded an FHC Guitar Mike for a gold neck rod, but it took a bit of convincing and a bunch of chatting about jazz guitars, DeArmonds, and so on. I couldn't find any other leads on that elusive neck rod. Good luck!Last edited by rpguitar; 05-27-2012 at 08:00 PM.

Hi Roger,
How does the DeArmond 1100 compare tone-wise with the Seymour Duncan/Jason Lollar/Kent Armstrong Handmade Johnny Smith pups or other pickups of this ilk such as the Lindy Fralin or Tom Short floating pups or the Benedetto S6? What makes the DeArmond 1100 special?

Thank you, JasonC and Roger. There's no turning back from the DeArmond now for me.

the pickup on this guitar was a DeArmond Rhythm Chief 1100, with adjustable pole pieces. Even better than the floating pickup that is actually named after said retired guitarist from Colorado.

That's a cool story about the unnamed but obvious guitarist. I wonder what the actual guitar was that had this 1100 on it?
After agonizing for a long time, I decided to mount an 1100 on my L-5 for three reasons: 1) It is period correct; 2) It is befitting of the L-5's status in terms of general marketplace consensus; and 3) Only the DeArmonds (Rhythm Chief and FHC) and the Kent Armstrong 2D would fit under the strings at the end of the fingerboard on my 1947 guitar. It was extremely frustrating, but there was 1/32" of needed clearance that just would not magically materialize, no matter how long I thought about it. The only pickup among these with adjustable polepieces was the 1100. I felt that was essential, because I like to use both nickel roundwound and bronze strings from time to time.
So while I am extremely happy with the setup and am "done" futzing with this L-5 as a result, I can't necessarily claim that the 1100 is God's gift to all floating pickups. I mention this only in an effort to keep you grounded in your expectations! After all, it is very expensive, especially if you find a gold one that is nearly pristine like mine. Of course I was thrilled to find such an example, because it is the perfect complement for my blonde L-5. But it cost about 20% of what I paid for the whole guitar (which was in itself a very good deal)!
That said, it ended up being one of those things that was done just right, with no expense or effort spared, and while it was painful at the time, I have no regrets. It helps me enjoy the guitar a lot more rather than constantly wondering "what if?"
Good luck and go for it!

I have not heard the Statler, at least not in my own hands. I exchanged friendly and informative emails with the fellow who makes them, though. His pickup was 1mm too tall for me to use. I was quite disappointed!
-
Has anyone here A/B'ed the FHC and both Rhythm Chief 1000 and 1100 on the same guitar, perhaps with nickel strings? The RC 1000 is twice as much and the 1100 can be three to four times more than the FHC. I really love my FHC, but I wonder what difference should be expected with the two higher end Rhythm Chiefs.

My Solomon has a Kent Armstrong 2D on it, which is quite shallow, but there is actually plenty of space for something deeper. Also, Erich initially built the guitar as an acoustic, and we added the pickup later when the guitar was back at his shop. The end of the fingerboard required surgery in order to do that. I let Erich take care of it and did not ask too many questions. If you had a guitar purpose-built to have a mounted pickup, you'd have no issue I'd imagine. I'm sure Erich would do what you need/want.

Another option for you is to have someone like Pete Biltoft make you a version. Pete is great to work with and does good work. I have him make the DeArmond clones I put on my guitars. I sent him my vintage Rhythm Chief and told him I didn't care if he had to destroy it to figure out what makes it so great and then make me an adjustable pole version. His pickup sounds very very similar to my vintage DeArmond 1000 but with adjustable poles in a Johnny Smith style package. I need to do a good video showing how that pickup sounds.

As an aside, I have always theorized that the Johnny Smith pickup was trying to be a humbucking version of the DeArmond but I have no verification it's just my hunch.
