Mailist to discuss all issues regarding the Digitech GSP-2101 Guitar FX Processor

Hi guys!!I'm new here and i recently acquired a 2nd hand Digitech GSP 
2101 w/V3.00 upgrade chip(comes with the power cord).I bought from an 
eBay seller from the states.
I'm currently residing in Singapore.
My question is:

- at the back of the unit it states 105-130VAC 60Hz for the supply 
but my country suppply mains are 230-240VAC 50Hz instead.Can the unit 
be plugged in the mains or do i need to switch for a voltage selector 
in the unit itself?

-if there is no selector and i cant plugged it directly, do i need to 
buy a transformer to step down the supply voltage to 105-130VAC 60Hz.

-will the unit work if i plugged it to a 105-130VAC 50Hz transformer 
instead of 60Hz?And what power rating is recommended?

I hope to get some sound advice from you guys here as i read a lot of 
good reviews about this old product.I still do have my trusty RP-12
(the distortion is awesome and i hope the GSP is too) and a current 
GNX3000 workstation which i feel lacks the anologue touch on the 
distortions.
And btw i have not plugged the unit to my country standard mains 
yet.Please help me out here!Cheers!

I wouldn t plug it in directly, I think you will fry your 2101!! I believe that you need to re-wire your power supply circuit board, I know that that there is

Hi Paul,

Thanks for replying that fast...dont worry as i said earlier i didnt 
plugged the unit to the mains as i have some technical knowledge 
too.I did email Dieter from his website as i dont know he has one 
here.
I checked as you instructed and is this what you are refering too?

Seems like i need to resolder the resistor to the 230-240VAC on the 
circuit board.There is a "R228" on the 230V and "R229" on the 
240V...what does this refers too?Resistor value?

Yes - probably just a simple swap of the resistor in the circuit board - don t really know for sure, but obviously it is designed to convert for different

The reconfiguration is easily done. There's a jumper (actully a zero-K 
resistor) on the small power circuit board (i.e. where the power switch 
is) and you have to unsolder that and re-solder it to 240V.

It's pretty obvious where once you can identify the spot -- the circuit 
board is labelled very clearly.

...and then you can run off to Funan center and buy a computer power 
cable and plug it into the 3-pin 13-amp socket.

Hi Adrian,

The circuit board you are refering to is this the one?(click on the

Btw what a zero-K resistor?I do see a 230V and 240V jumper space on 
the circuit board but there's no resistor except on the 110V.

Hi Steve,

Thanks guys for the insight and tips...i have successfully removed 
the 117V resistor and moved it to jumper on the 240V space.Turned the 
unit on and all set to play!
Tried it and i am very happy with the outcome.Now the next thing to 
do is get my hands on the PPC210 card....anyone know where i can get 
one?Dieter sold his last piece yesterday on eBay.

That's the correct resistor. It has a resistance value of zero ohms 
(black stripe), and basically acts like a "plain wire".

Sounds like you have done the mod and its working perfectly. :)
