Amplifier Discussion / hiwat maxwatt g100r problem
January 17, 2014, 09:53:50 AM
Hi everyone !
I have found a simmilar topic but not replays for a long time so I decided to start a new one.
Yesterday I have recieved used Hiwat Maxwatt G100R and when I plug the guitar signal was waaaaay too weak and amp is producing a kinda farting sound. I have mess a little bit with controls, switches and everything and channels were switching, gains were switching (for tone controls is a little hard to say from obvious reasons)...I checked cable, input, guitar (replace guitar and cable) and nothing changed. Then, all of a sudden it came alive and everything seems to function perfectly. Then I played guitar for a while (15-20 min) and - BAM- how it came, it goes same way, started to fart and cut output signal to 5% (not dead completely). Then I try to hit it from up above (Russian principle  :tu:) and then it start to come and go, than it went for good. I had to go somewhere but when I come back after few hours I plugged it in again and-it worked perfectly. Than I become pissed off and, while guitar was plugged in and on the drive channel, with one hand plucking the guitar and with another hand I grabbed it for handle and rock it back and forth for some time, trying to provoke upper mentioned situation. And after 10-15 rocks it went off the same way.
Afetr that, I have try to rock and pull wires from speaker but nothing have happened. I have plug out the guitar and amp from outlet and roll amp on the front side and look at speaker again, checked wires but everyrhing seemd to be ok.
Today, I contacted previous owner but he swears that the amp was in perfect order.
Is it possible that something gone wrong in transport ?
Please, if there is anybody that experienced the same with this amp, or somebody that think that he knows what's going on, give me replay !
Thanks in advance !
