The AFD-45 is perhaps my favourite Ibanez guitar ever. The arched and contoured bubinga body, oiled finish, wenge-bubinga 5-laminate neck... these were boutique-quality instruments!

Here's a few sites Google gave me:

Good luck finding one! They're pretty scarce.

That particular AFD-45 belongs to me now.

It really has sophisticated electronics, on which I'd like to shed some light here. I hope you guys are interested.

First of all, it has 3 Ultrasonic REF2 pickups. The Ultrasonics are a piece of pickup making history yet not widely known. According to what I found out, the original series was manufactured by the OBL/Bill Lawrence company in Germany in 1985/1986. The Ultrasonic distributor went out of business after a very short period of time and the pickups were sold off very cheaply. I have seen these pickups on late 80's Tom Anderson, Zion, Valley Arts and Lake Placid guitars as well as on some custom luthier efforts. They are passive pickups with pronounced linearity over the frequency, allegedly highly suitable for heavy effects processing -- like a "passive EMG"-type pickup. The REF2 model used on the AFD-45 is a stacked humbucker, and each of the three pickups is mounted and wired separately.

Here are the electronics: (pretty complicated wiring!)

1x volume pot
1x tone pot
1x 3-way mini switch for pickup selection
1x mini switch for coil-tapping neck pickup
1x mini switch for activating active boost circuit
1x 6-way rotary switch for even more pickup selection and coil-splitting

The active boost circuit has a separate battery compartment, its cover is mounted by threaded screws (a neat detail). The gain can be adjusted by a small trim pot inside the electronics cavity, accessible with a screwdriver through a hole in the cavity cover. I will try to find out if it has a "flat" frequency response or if there is some midrange boost involved.

Nice score, by the way, and thanks for the detailed rundown... post photos, please! And if you ever consider parting with it...

I think you and i share many common tastes in our guitars!

The previous owner and I are friends. He decided to go for another AFD-40 with the IBZ USA pickups and part with the 45. On the other hand, he wanted the guitar to get into good hands and stay in the family, and that's what friends are for.

I am now in the process of cleaning and setting it up. I can take intermediate pictures of the disassembled guitar, but meanwhile look at these: (click for closeups)




@Darren: About our common tastes: What kind of guitars do you like?

Thanks for that GAS renewal.

Here's another shot:




I have now completed the overhaul and also (finally!) fully understood the load of controls! At first, I thought it's really complicated, but when you break iit down, it begins to make sense.

First of all, there is a 3-way toggle switch (the leftmost switch with the larger knob). This operates as if middle and bridge pickups were one; toggling between this, the neck pickup and both together. Then, there is another mini switch to split the neck pickup. The rotary switch with the slightly small diameter knob is dedicated to both middle and bridge pickups. It has 6 position and the wiring is very clever, thus providing many possible combinations of the 4 coils of (M)iddle and (B)ridge position:

1. M humbucking
2. M parallel
3. M+B humbucking
4. M+B parallel
5. B parallel
6. B humbucking

The third mini switch is used to activate the booster circuit, which is located on a printed circuit board rear-mounted to the cavity plate.



Four wires connect the active circuit: Red+Black: 9V supply voltage and ground, Yellow+White: in- and output. The LF 441CN (a low power JFET input operational amplifier manufactured by Motorola) seems to be the only active element in this circuit, the rest are just resistors and capacitors plus the trim potentiometer.





Although the guitar was made in 1990, the serial number follows the pre-1987 scheme, namely a letter to indicate the month of manufacturing, the year in two-digit writing, and a 4-digit monthly running production number. (more info on serial number dating on Rich's site...)



Read some background information about Ultrasonic pickups on this wrap-around package from a new old stock REF3 pickup.

Here's a little update. After quite some playing time and after having made myself familiar with the electronics, I have made a decision: The pickups will be replaced.

Although the linearity idea is good and the wiring is intricate yet efficient, I personally don't like the Ultrasonics' sound at all. It's thin, boring, lifeless and they have very low output and bad dynamics. I will have German pickup specialist Harry Häussel make a custom wound full-size humbucker for the bridge position. It will have a custom-made base plate to avoid any wood work on the original double-single-coil routing. In the neck position I will install a Seymour Duncan JB Jr. since it has a parallel base plate. Also, I will come up with a modified wiring scheme providing split functions for both future pickups, eliminating the rotary switch but retaining the booster switch.

Then I will have both things, that is great looks *and* great sound. The latter is missing with the stock Ultrasonic pickups.

Here's the update. I received the custom-made bridge pickup and installed it, along with a Seymour Duncan JB Junior at the neck position.

This picture shows the special base plate to fit into the double routing:



And this is a view of the body with the new pickup configuration:



Let me tell you, the guitar sounds so much better now. I'm really happy that I got rid of the Ultrasonic pickups and have this "classic" configuration without having to do any routing.

I also realized the planned wiring modification. Here's a look at the upgraded electronics specs:

1x volume pot
1x tone pot
1x 3-way mini switch for pickup selection
1x mini switch for coil-tapping neck pickup
1x mini switch for coil-tapping bridge pickup
1x mini switch for activating the booster circuit

Awesome.

Who custom-made that bridge pickup for you? Is it a full custom, or did you just have a custom base plate made for an existing pickup?

It was Harry Häussel of www.haeussel.com who made it for me. He's sort of a pickup Guru based in Germany who manufactures his own range of pickups as well as OEM types for guitar makers like Rainer Tausch, Siggi Braun, FORGE guitars or Juha Ruokangas.

My pickup is basically a stock pickup "core", F-spaced, with coils & magnets & bobbins & screws, but with a custom base plate using the exact measurements I took from my AFD body. If you look closely, you see that the base plate is flat and the mounting ears are not bent in a "straightened Z" shape.
