MoonBassAlpha Posted August 3, 2014 Share Posted August 3, 2014 Try linking the send return sockets with a known working lead. If these are rarely or never used they can get tarnished and mute the signal. Quote Link to comment Share on other sites More sharing options...
GregBass Posted August 4, 2014 Share Posted August 4, 2014 When you say the fuses all look fine, have you actually tested them with a meter? If not, then either do that or just replace them one by one. Quote Link to comment Share on other sites More sharing options...
geoham Posted August 7, 2014 Share Posted August 7, 2014 Few things to try: Plug straight in to the FX return. This bypasses the pre-amp. You'll still hear the bass if you crank the master volume. If you still get no sound, it's likely the power amp is gone. On a similar note, see if you are getting any signal from the FX send. (Perhaps run a jack cable to another amp - keep the gain down though - or even a tuner). This will confirm your pre-amp is working. Try a different speaker cabinet Failing all of the above, either continuity test all fuses with a multimeter, or replace them one at a time.
