Build Your Own Clone Message Board

Hi People. I have just built the Wha drop in and fitted it to my white dunlop enclosure.
I practiced my soldering skills first and laid everything out in order and labeled it first (great tip!!!!!!)
It works brilliantly . . i am so happy, and will be building more soon.

I need help with the Inductor mod. I cant source a 3 pole 3 position rotary switch anywhere so i have ordered a Rotary switch 4P3T

can i use this for the same outcome (1 inductor 2 inductor 3 both in series 4 empty)

I would really appreciate it if someone could help with the wiring of this . . This was my first build and i'm still learning.

Many Thanks in advance

You are thinking of it backwards... a 4P3T will only have 3 positions, just like the 3P3T. So your positions will still be 1= inductor #1, 2 = inductor #2, and 3 = both is series. You will end up with an empty pole, and 3 empty pins, but this will not effects the positions.

Most likely, your poles will be marked with letters... A, B, C, D. Around the outside will be 12 pins, numbered 1 - 12. You will wire it just like the 3P3T in the instructions... except that the pins "1, 2, 3" shown near B will be 4, 5, and 6 (respectively) on your switch, and the "1, 2, 3" shown near C will be 7, 8, and 9 on your switch. Just leave pole D and pins 10, 11, 12 empty.

hi, Thanks so much for your help. That's great.

After doing a bit of digging on the forum i found a mod for a 4 positin switch

here: viewtopic.php?f=33&t=2629

My new question is. Do I wire the rotary switch as per the instructions on the pdf and just add the jumpes listed below to make it work?

So to add that to the switch you would set it from 3-way to 4-way.
On Post A you would jump pin 2 to pin 4
On Post B & C you jump the pin 4's to each other.

That should give you:

position 1 = inductor 1
position 2 = inductor 2
position 3 = inductor 1 + inductor 2 in series
position 4 = inductor 1 + inductor 2 in parallel

I think a lot of people are having trouble getting a 3 pole 3 position switch and If i can get this to work I think this mod should replace the 3 position mod specified on the PDF (it gives some nice options and it looks like you dont need to remove the 0 resisor from the pcb to do it)

Thanks again! Best Ed

OK... again... a 4P3T switch does not have 4 positions. It only has 3. Four positions would be a 3P4T.

P = poles (connections)
T = throws (positions)

Oh dear, i think i inhaled too much solder fumes when I built my Large Beaver yesterday . . . Thanks for the help!!

I have been paying my jaguar thin skin through it all day, the tone options with a jag (especially with the bass cut switch) are endless.
For anyone who has ever wondered what use that switch is on a jag . . use it with a beaver amazing!!!!!!

Will the rotary switch that was included with the old Tri Boost work? It has 3 poles (labeled A, B and C in the middle) in the middle and 12 on the outside (numbered 1-12 of course).

Never mind. I just found the answer in the "Buffer and Inductor Mod" thread.
