Subject: Re: Alas, to mic a Small Amp

The JT-30 requires a very high impedance. If the impedance of
whatever you're plugging it into is less than a meg, it will sound
very thin and shrill. By the time you get any volume, it'll feed
back terribly.

Plug the mic directly into the amp and set it for CLEAN. Compare
that tone and volume with that with the pedal. If it's thin, the
pedal has a low impedance input. You could build or buy a buffer amp
(like my MikeMojo). Or run the JT30 directly into the amp and use
the pedal with the PA mic. Personally I like this setup better.

I suspect you like the small amp for the distortion. Keep in mind
that distortion is at the expense of volume. If you want more
distortion, you will sacrifice volume before feedback.

It's also possible that the amp (or amp/pedal combo) has a rough
frequency response that exacerbates feedback. An EQ might be
helpful.

Miking a small amp adds the "feedback" of an additional mic. This
can be minimized by putting the mic as close as possible to the
speaker, so you don't need to turn it up as loud. Try both the front
and back of the cab.
