I'm gonna start on to my 3rd PF500.
#1) I bought it brand new from
Sweetwater. After 6 gigs or so, it died. It made it through the whole night of 3 sets of 80's music. I play in an 80's tribute band. At the next gig, it was dead on arrival. I turned it on, and got the fault light. I called Ampeg and they sent a replacement and were very nice.
#2) I used this for approximately 4 gigs and got the same problem. The last time it was working, it was a 4th of July festival. It made it all the way through a 1.5 hour set. Then, at the next gig, dead on arrival again. I turned it on during setup and it was fault light. I called Ampeg and they had me take it to a service center.
#3) I am still waiting for the service center to complete the fix. But, today, I am having doubts of whether I can rely on it when I pick it up. I was gonna buy a Hartke LH500 today and sell the PF500. I decided to sleep on it and think this through carefully.
I wonder if it is something that I am doing to cause the issues. I've read the manual, careful with my gain, play harmless 80's music. Does it need more cool off time after a gig before being packed away? Does it not like octave and synth effects from the Zoom B-3 (important in 80's music)?
The rig that I have been using:
Fender 4 string Jazz
GK MBE115
Zoom B3 pedal
My former rig, which has been saving my ass with all these issues, and has been awesome for 15+ years, good thing I didn't sell it is: Alembic FX-1 preamp > Carvin DCM1500 amp. I bought the PF500 to cut down on weight and size.
