Just bought a DSL100HR head and noticed that it is self switching from clasic gain to ultragain chanel in a random way.
It happend 3 times in aprox. 20 hours of functioning and 2 times I was not even playing the guitar, the amp was on on classic gain crunch and switched suddenly on the ultragain.
I do not use the PEDL-90012 foot switch, I use instead a midi connection from loop controller Harley Benton FXL8 Pro ( everything works as expected here , could program and switching works fine through midi). The amp works perfect in rest nothing to complain except this strange behavior.
Q: any idea what is the problem and if/how can be fixed, is it something common ?
Thanks in advance!
Without seeing the amplifier it is hard to say, does it occur without the MIDI controller plugged in, if it doesn`t then it may be a compability issue.
Does it do it without anything plugged in? and does it occur with the correct footswitch plugged in?
Thanks a lot for the answer!
Here is what I checked so far:
1. used the PEDL-90012 foot switch and no midi connection for aprox 10 h --> problem no longere reproduced
2. used the amp without anything plugged in for aprox 20 h --> problem no longer reproduced
3. used the amp with midi Harley Benton FXL8 Pro only for aprox 10 h --> problem no longer reproduced until now...
so..how could this be.. ?
could be something else responsable about the described problem ? (e.g. how loud I use the amp, how much gain....)
Thanks a lot for the answer !
Is it possible also to have something to do with the electrical power fluctuations (e.g. instead of 230 V constant to have lower values 200 V - 210 V) ?
Are/could be that the relay responsible for the channel switch be influenced by the electrical power input ?
