: I've got a little GK MBS combo that I use mostly for electric 6 string and acoustic upright... sometimes it sounds GREAT and I love it and I feel fortunate to be able to have an amp that I totally don't deserve.
: Sometimes it distorts. Now, I play a lot of jazz, and though distortion has its place in the world, when I'm in a restaurant with 70 year olds who want to hear Autumn Leaves and How High the Moon, distortion is the LAST thing I want to deal with.
: The problem seems to have to do with the amp using a LOT of power. Usually it is fine if I'm practicing alone in a room where not much other power is being used. Does anyone else know anything about this/have any solution ideas as to how I can distort-proof my rig? Thank you!
Hey...I can't be absolutley sure, but It sounds like the problem you may be having is what is termed a "brown out." This is when the power running through the grid (however big or small) drops in voltage (usually) or amperage (rarely).
This MIGHT be the cause of your problem, but I can't be sure...now...if you do think it is power draw affecting your amp, there may be a few things you can do...first off, check all the power(extension)cords being used, if there are any. Look for tiny ones...you want big, heavy thik ones, that can handle the amount of massive electrons moving through them that your amp draws. If not, they may become hot (check this) and can even become a fire hazard. Also, splitters are a VERY bad idea when it comes to high power-drawing amplifiers. Try to stay plugged into your own whole outlet. Don't even let the other plug be used, if at all possible. Something that may at least help you diagnose this problem is a power monitering strip by Furman. Many of these tell you the voltage incoming, and condition the power so as to be clean. These can be especially useful, as voltage anomalies can actually damage you amp (low as much or more than high voltage) I know, not cheap, but your rig is very important! Other than that, I can't make too many more suggesions, except to make sure that you at least try running you amp at home just like you would at a gig when this would happen. Full volume and play time. Sometimes, when a power amp is driven too hard too long, it will do exactly what you are describing. Good luck, and feel free to e-mail me if you have any questions.
