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

Does anyone know if it is worth it to buy the upgrade chip for the 
GSP 2101 to bring the software version to 3.0.  My second question 
is;  Is it pretty hard to do????

Hi Ryan:

I've included copies of messages I sent about two months ago to another
GSP-2101 owner who was trying to decide whether or not to upgrade his 2101
to Version 3.00 "software".  Hope this helps. GP

*****************************

Your GSP-2101's software version is displayed during the GSP-2101 power-up
sequence.  Make special note of whether or not a lower case "a" follows the
software version.  If it does not, this means you're running a 10MHz clock
rather than the newer 20MHz clock.  If this is the case and you want to
upgrade your software to the latest version 3.00, you'll need to return your
GSP-2101 to the DOD factory in Sandy Utah so they can install the new clock
for you.  Unless you live near Dieter Waechter in Germany.  He can probably
install the new clock for you in his sleep.

Upgrading your GSP-2101 to Version 3.00 firmware is not a bad idea.  You'll
get lots of new features for the price of the two chips.  They auction on
eBay regularly for less than $25.  Version 3.00 also allows you to use
various software packages available for remotely controlling your GSP-2101
should you be interested in that avenue.

So without the lower-case "a", this means you have the 10MHz clock.  To
upgrade to Software version 3.00, I think you will need to upgrade to the
20MHz clock also.  I don't know how to upgrade the clock but you can contact
DOD / Digitech directly and ask them if this is possible for you to perform
without having to send your unit back to them in the USA.  Their web site is

They have a form you can fill in on-line to ask for technical support:

Installing version 3.00 EPROMS is easy.  You simply pull out the old chips
(two of them) and insert the new pair, making sure you have them oriented
correctly and that all the legs are correctly seated in their slots.
