Solid State Guitar Amp Forum | DIY Guitar Amplifiers

 Hello Forum,
  I've had my Yamaha G100 now for about 4 years. I really love this amp. There is a jack on the back of the head labeled "Record output". Because I have no way of recording with a mic i would like to try using this and I have with no success.
  I believe I'm using or doing something wrong. The schematic says "+4dBm nominal  +31.2dBm max  For 600 ohm unbalanced lines".

So far Ive tried using a guitar cord from the record out to my instrument in jack on my Line6 and got nothing. I didnt want to risk frying anything so thats all Can anyone explain what im doing wrong and how I can properly use this jack. Everything on the amp works perfectly (I bought it used) so I dont think anything is wrong with the amp.

ANY help on this would be greatly appreciated Thank You

*There is* line level signal out of that jack, so it should work.

Please post schematic here so we can check where does that jack pull signal from.

Although there are about 6 different G100 schematics, all of them basically take the speaker output & resistor the signal down for the record out.
To be specific please advise the exact model amp.
