Roland GR-1 volume droped

[alex frias]

The output volume (phones and stereo line outs) has droped a lot. It's used to have a very strong output. I've stayed almost 6 monthes with it stoped in it's case. I was back to it and was amazed by how low volume level it achieved... The sound seems just a bit distorted, but they are all there. The effects section seems fine too.
Thanks for any kindo of help!

Does it have an output level switch that selects between -10dB and +4dB?

Perhaps on the back panel or a software switch.

I didn't find any evidence of such kind of switch, soft or hardware type... I even thought about the MIDI volume control, but that's not the case.

I'm still looking for an electronic schematic of the beast. Roland was kind but not of any help.

Any info would help...
