Re: [Harp-L] feedback





After reading FJM's post I checked to see wether the pot was doing more than reducing feedback and FJM seems to be right. The tone was changed by the pot. In my case, the tone got better when I turned down the volume pot (more colored and fatter, sounded a bit like a Marshall amp which is unusual for this amp) but that is perhaps dumb luck.

I guess it makes sense, as the mic pot alters the sound chain, in this case the pre-amp gets less signal, so pre-amps output is changed and since nothing is linear in amplifiers then the output is affected in an unpredictable way. This is a shitty state of affairs since it kind of means you have to keep trying things until your happy. Unfortunately components like mics, tubes and amps are expensive. Also it is not obvious that changing tubes will be better than using the pot.

Will play around some more tomorow, will try Richards approach using my son's KORG multi-effect unit. My main concern there is that it will sound "digital". Will also try his Tube Screamer pedal, normally (previous to today) the tube screamer to the clean channel of the amp gave me the best sound (fat and warm). Will report back for those who are interested.

Thanks to all who posted,

Pierre.

I just use the volume knob on the amp as my anti feedback device - if I encounter feedback I just tap the VC "counter clockwise" a tad bit and SURPRIZE, no mo feedback, works like a charm!!
