I just got a new CODE50 and am extremely pleased with. My problem is everything on the Gateway app works, but the GAIN, MIDDLE, VOLUME, and PRESET knobs on the amp don't work. I'm really pretty new to this so I'm not sure if something is wrong or I'm doing it wrong but every other knob works correctly.

so what series is the vavlestate 10 and valvestate 40V?    can't find them in the manuals section

HI just got  a new (3 days old) JVM 205C and played it a couple of times then when I went to turn it on again it will not make a sound!

It starts and all the tubes light up but when you turn off the standby nothing happens and no sound at all comes out, not a click as if the standby swith is doing nothing.

I did read the manual about the FX loop button muting the amp without effects plugged in but I have tried everything I can think of so far, guitars, leads other power sockets but no go!

Anybody have any ideas???

Thanks

is there a downloadable manual in Spanish language available for the CODE 25?

Hello, is there a downloadable manual avaiable for the MG100 HDFX?   Also, what footswitches are compatible with it?

Thank you.

 The 2555x user manual says that the d.i output is frequency compensated and meant to be used to feed a mixing desk or a slave amp but I find this confusing because the frequency compensation is usefull only in the first case and probably really bad if you feed a slave amp and cab.

can you elaborate please? 

Hello, what is the warranty on the Code 50? Couldn't find it in the users manual. Thanks!

I am running a Lexicon MX200 thru the serial loop on my JVM 205C.  Sounds great but when I turn off the loop using the front panel selector button via footswitch or manually its still on and making whatever effect I have chosen.  What have I not done correctly?

I purchased a G50R CD from a friend. Is there a manual or any downloadable info on this amp? I would like to know more about the CD input on the back and how it's used. I really don't know much about it so any info is helpful.

Thanks....

Is there a printable Code owner's manual?
