This MG15 I have (yeah yeah get over the fact that it's crappy and dead sounding and w/e)...the knobs work on some points, not on some others - and it's incredibly fiddly setting them at a position that is working. Sometimes the volume comes but the sound fizzles out in a second after playing and holding something. On some points the sound comes out loud and clear and sustains - yesterday this stopped too, ie the amp was essentially useless without repair. Took it to Bhargavas today, they say - 250 service charges Then according to them the knobs need to be replaced, so, 220 per knob (x4) and they say the OD switch needs to be replaced (that isn't working either, but no biggie because I don't use distortion), so, 190 for one switch ...1320 bucks. I've held off repair for the moment. Asked the person to whom the amp belongs, suggested we split the cost half, then we decided to take it to where he bought it, OnStage Lajpat Nagar. Figured repair might be cheaper (If you wish to know why I'm trying to repair this amp, it is because I'm ~80% close (financially) to my next amp, which should last me for a while. But that amp could be a little while away.) Is the Bhargavas quote a rip off? I need to have an idea for the next trip to the repair shop. Also, anyone know of an amp repair guy around here in Delhi?
