That is probably a momentary switch that is dirty and sticking. These onboard effects on guitar amps are usually nothing more than a computer sound card and I've found bad connections going to and from them as well. I do think that switch is dirty and sticking, though.

Flexwave 120H Speaker wire shorted amp won't work

Solid state amps are very subject to blowing out the output transistors if speaker leads get shorted. Take it in for repair.

It sounds like the DSP processor is either about to go out, or is mostly there. Have a qualified amplifier technician take a look at the DSP. Also look up the cost of a new one.

Hope that helps!

I have a Crate GT 15, not getting anything to the speaker when I plug in.

Do you have electronics experience? Inspect the amp for broken or cold solder joints and any burned components. Check to see if the fuse blew and that the output IC's or transistors (not sure what Crate used in these) are not bad. Check your speaker wire as well.

Not good. If you have electronics experience, you can replace the power amp IC to fix it.

Plugging line level into my crate TX15. all inputs sound distort

guitar amps are all set to a low Z resistance configuration. wich are made for guitar only. make sure you are using the right cables.
you need sheilded guitar cable not unshielded speaker cable in many cases these cables look exactly the same. look at your cable look for the words speaker or instrument. you need the instrument cable. if you still have that problem. then you may just not be satisfied with the quality of the amp it self.
