Hi
I'm new here but has anybody measured the impedance on an Robot SG Ltd?
There should be 498T in the bridge but when I measure at the neutric jack outlet I read 122k. :D
So there must be some electronics inside between the pickup and the jack out
Sadly 8) I must say that it has influence on the sound too.
There is more cut-through(middle) on the Robot than on my 92' SG Standard(also 498T) and it's easier to be heard in my band.
So mayby a pickup change in my beloved Standard could compensate that

Tazzy:Sorry about the overdue response. Make sure your volume and tone knobs are dimed. Not sure about the Neutrik jack. Robot SGs should have a 1/4" patch cord jack. You could open up the CC cover and go off of the leads coming from the pickup into the pot.

Hi
I will try to measure inside the CC.
After analyzing the output from the SG Standard & the Robot with Harbal (any Spectrum Analyzer would do the job), I can see that the RMS Power level is lower on the Robot (with same pickup height) and the Robot has an earlier HF roll-off.
So maybe something is wrong with the pots :-\

I'll check mine and have it up tomorrow. Do you use trs or standard cable when charging, I'm having troubles...

Hi D-DAY

I'm using the standard cable.

From the manual :

Pull MCK out, turn to C LED and press display

Your current charge level will be displayed for about 3 seconds.
The level of charge will be indicated by how many green LEDs
you see (betweeen 1 and 10).

Now you will see a flashing red battery symbol on the MCK,
indicating your system is looking for its charger.

Plug in the AC power plug of your charging unit and the charger will flash red, too.
Connect the charging unit to the guitar with a standard guitar cord, and when
the system begins to charge, the charging unit will flash green, and a running display
of green LEDs on the MCK will indicate charge level.
The charging unit’s LED will flash green, too.

For optimum performance, you will want a charge level of 8-10 green flashing LEDs.
A fully charged battery pack will show a solid blue light on the charging unit and the
MCK’s display will switch off automatically.
Push MCK back to its normal position when charging is complete.
A full charge should take no more than 90 minutes.

Well I checked the resistance on the Mini-Humbuckers on my SG and came up with 6.0k for both, checked the stock blade style treble P-up in my 76 Marauder and got 2.3k, while the non-original humbucker rythym P-up was 6.7k...

Ok what about those of us with a custom sg? How do we test the middle pickup?
