These humble practice amps have sold by the 000s I reckon based on the number of enquiries I get any way. Two channels, fizzy distortion, chorus, reverb effects and conections for headphones and line in audio. Great practice bundle especially practical for students and people on the move.
The few issues I have encountered are
- channel switching issues where the the amp will get stuck in either clean or distortion and refuse to budge. This is caused by a problem with the switching controller chip and is very repairable.
- Power amp failures caused by blown chip amp part, again a cheap repair. May also cause damage to the amp’s power supply.
- Of course front panel damage to pots and the horribly cheap 3.5mm connectors on the front panel. The headphones signal interrupts the output to the speaker so any damage or dirt on that connector (like age realted oxidisation) means that the signal will drop down a bit just when you would prefer it not to.
All of these faults are highly repairable but the only thing is that the PCB tracks are very weak and easily broken. If you do attempt a repair keep your soldering iron temperature low and be patient.
