[Harp-L] Re: Controlling feedback




John,
The amps without a mid control still sound because the mids are preset and run through a capcitor, rather than a potentiometer, which is a variable capacitor. I am pretty sure all the pre CBS amps with a mid control are like that, and just as a side note my VibroKing which is a newer Fender (early 90's) has a mid control, and guess what, when all the tone controls are rolled down, no sound. Tone controls in these Fender circuits are a cut device, and when the whole spectrum is controlled by the pots, you can cut all frequencies to 0.

So when you turn your treble and bass down on a two control Fender amp you still have all the mids from the "pre-set" mid cap. I do agree that far too many guys just turn everything up too far, worst offenders being guitarists of course. I rarely turn the treble up past 3 on most of my guitar amps when playing Fender guitars, maybe 5 with a Gibson. Half the guys I've played with over the years are between 7 and 12. Hurts my ears!!!

With a super reverb or a bassman that would be no sound at all, no feedback either. JDH

Nonsense. I've got a Super Reverb (Reissue). In either channel you can turn all the tone controls down to "1" plug in and play and you get a decent level of sound. Obviously, the volume control can't be turned down when you do it, but all the tone controls certainly can. Don't know about a Bassman, though. And i don't know about silver face Supers that have a master volume control.

I just tried it w/my Super and you CAN turn the tone controls
completely down on the dry channel which has 2 tone controls, but you are absolutely correct, it won't work on the reverb channel which has a midrange control. i must have done it with the dry channel and simply assumed it would work with both. You should post this explanation on harp-l.
