A few parts came in today and I thought I'd put up comparison shots.
I ordered a few things from Rich at ibanezrules and a few comparable items.
I received two 500K Ibanez Alpha pots, made in Japan. I have these in my S5470 and I really like the way they feel.
I also received a 3PS1CGAE5, CGAE5 for short, which is a 5-way switch that'll fit the S series bodies and work for an H-S-H pickup configuration (but not an HHH which needs the VLX91 switch).
For comparisons sake, I ordered two of the higher quality CTS pots with brass shafts from Allparts as well as two Alpha 5-way switches from an ebay vendor.
The advantage to the CTS pots is they have linear pole spacing and are easier to line up with a terminal block. The Alpha poles are splayed so it's not as easy without some bending but it's doable and I wanted measurements for those pots too. And they're made in Japan and not Korea or China.
The two 5-ways are virtually identical with the Ibanez (Cor-Tek) circuit board being a bit more transparent. Other than that, same pole spacing, same number of poles, hell, except for the Alpha or Cor-Tek, they look identical. But the Alpha is about 1/6th the price. How will it hold up? Not sure. They both have the same "feel".
Once I get the new terminals in, I should have a package that's actually smaller than the Seymour Duncan setup. I've thought about using mini-pots as well and it's completely doable.
The Bourns pots that SD uses are the cheap ones which cost about the same as an Alpha and are probably made in China. They're not the $15 units with the brass shafts and composite casing. The Allparts CTS are supposedly better than the standard CTS but probably not as good as say an RS Guitarworks matched pot.
Pots. The CTS shaft is about 1mm shorter than the Ibanez.
