Hello,
I have an Ashown RM420. It's a great amp and I have worked it hard for about 4 years. Recently I have been haveing some proiblems with volume and gain.
to get the sound I like I have the shape button in, boost the low mids to about 3 o'clock small boost to bass and to treble. I use a foot pedal to kick in distortion and some octave. Some gigs I do don't go through a pa so I use two 8 ohm cabs and volume has to be at about 3 Oclock +.I generally keep the gain under control so even during my most enthuiastic playing the VU stays out of the red.
Recently after some time I seem to loose control of the gain, every note i play the VU shoots staright to max and I get a really nasty distorted sound.
Although the amp does not feel hot my gut tells me it is over heating,
Can anybody shed any light on whats going on?
Thanks,
