Twin Tube GFX-1

[Iperfungus]

So...I'm about to buy a Digitech Twin Tube for 60 euros and that's a good deal, since it's in good shape and 100% working.

I'm planning to pair it with the Zoom 9150 for missing effects and go through the Marshall 8004 power amp...

I don't think you can go wrong with that, good luck!

I think I'll be happy with a third rack...  :headbanger:

[Iperfungus]

Got it!  :banana:

My brother-in-law has it at home...

I hope to have it home ASAP!  :headbanger:

Digitech came good!! Got schematics if anyone needs them. Still loving this thing btw.

Looks like Sparker has the schematics, send him a PM or maybe he can post them here as I'm sure other GFX1 owners would like them  :thumb-up:

[Riccardo]

Yes, I think so......the schematics are always welcome......I have tried to send him a private message, but i'm not sure to know the right way to do it.
Infact he haven't answere.......sorry for my english....
I will wait few days, than I will try again to contact him.
Digitech have sell a lot of GFX1 and on google is impossible to found it.

Hello Riccardo, your english is good,

You could try what Sparker did and contact Digitech.To send a PM select the My Messages tab, select New Messages in the left hand side menu, type Sparker in the To: field (it's case sensitive), enter a subject (not mandatory) say GFX-1 schematics, enter a short message and click Send Message button.Although I suspect you already worked this all out.  Give him a while to respond, he may not be around or looking.  Usually you get an email notification when someone sends you a PM but they don't always work (as I posted about in discussions).

Regarding schematics or service manual:
Contact Digitech for these - they will charge for it.

I usually can find schematics and/or service manuals, but some products have always eluded me, like the Digitech TSR24S - for obvious reasons, as this one was close to an Eventide 7000, and, as Digitech was bought up by Harman Kardon, who also owns Eventide, they want anything about the TSR24S gone from the net ;)

I haven't been able to locate schematics or service manual for the GFX-1, so...

However, I did find it for the 2120 on elektrotanya, using this query:
site:elektrotanya.com product schematics
or
site:elektrotanya.com product service manual

Best of lück

Hello to everyone, my dear friends.
I have write to digitech, but they told me that they can't give their electronic schemes due to their commercial politics. I understand that the know how is important but the Twin tube GFX1 is a 1992 product......I can't understand this. Then, they send my the list of USA digitech technical labs....but i'm in ITALY!!!!!!!! ;D ;D ;D ;D ;D ;D......They are crazy....Then, I have write to every single Digitech USA reair lab, but no one can give me the scematic by contract with digitech.
I have found the ELECTROTANYA like suggest....there isn't the gfx1 schematic, but I have found one similar. It can be important to have something to have a look.
I will try to contact "Sparker" next week......
thank you my friends. Rock'n'roll
Riccardo.

Nonono, they did not send you a list of Digitech repair centers for you to write to about schematics, but rather so you could send your Digitech product to one of these for repair.
It's just their way of telling users that they won't give way 'secrets'..
So, writing to these repair centers will likely be wasting your time.

All - apologies, should have done this ages ago, been away too long!! See attached.

Thanks
