My amp has no volume unless turned all the way up and only on the high input jack
check the "Gain" on the instrument you are plugging in ... if it is all the way down, that's the problem. If that's not it, check for a "Gain" control on the amp itself -- the is a volume control that takes care of the sound BEFORE it goes through the amp (pre-distortion etc.). Sometimes this is not with all of the other controls on the amp, so look carefully.
If it is not the gain on your instrument, and it is not the gain on the amp, then make sure you are not using too long of a wire to connect the two things. If you are using a 100ft cord to connect a guitar to an amp, there will be a lot of signal degradation in the wire, and it will be hard to get good volume from the amp since it is not getting enough signal to amplify.Try a shorter cord, and that might help ...
If all of these have failed, check the fuses on your amp. If there is a blown fuse anywhere, then your amp might not be getting the full power that it needs to produce the sound you are looking for (though a blown fuse usually cuts out ALL power through the amp, some models are built differently and this could cause your issue)
If none of these solutions work, try hooking the amp up to something else that you know works fine, to make sure it is the amp itself, not what you are hooking into it, that is not working right.
If all of this turns out to be an Epic Fail ... try speaking with customer service at the amp's manufacturer ... it might be a defect that they have seen before, and they may replace it, or at least give you a better solution that what I have done.
