for an archtop with a floater

is an accoustic amp preferable-especially with the typcial notch filters?
or
are they simply too bright /transparent for jazz

I think of an acoustic guitar amp as being like a pa, it's trying to reproduce and amplify the sound...

A guitar amp amplifies and colors the sound.

agreed-but was also thinking of feedback issues

An archtop with a floating pickup is an electric guitar for the purposes of amplification.

An archtop without a floating pickup, and either miked, or equipped with some form of piezo electric transducer, is an acoustic guitar for the purposes of amplification.

Run a guitar with a "floater" through a "regular" amp.

Consider this to be a general rule, while recognizing your mileage may vary from EPA estimates.

Ah, feedback issues...

I don't know if there is a difference in feedback between the two amps.

Re: feedback

I often find myself sitting near my amp. It makes a big difference in where I place the amp, I place it to the guitar neck side of me, if I place it on the side closer to the guitar body I'll feedback at pretty low volumes.

If I still get feedback after placing my amp on that side, then I start fiddling with my parametric eq.

I identify the note that is the same pitch as the feedback...
I translate that to a frequency... I know my A notes are 440 220 & 110 hz and the low E is around 80 hz. So I approximate the frequency. For me iit seems to often be around the B note on the 6th string which is about 120 hz.

I dial that frequency into the Parametric eq, pick a narrow Q, and start knocking down the db's until I've tamed the feedback.

So perhaps you want to look for an amp with a parametric eq, or get a pedal. It took me a while to figure out what to do with my amps parametric eq, for me it's exclusively used as a tool to reduce/eliminate feedback. (But when talking about mixing a recording, I use parametric eq's a lot when doing a mixdown, but that's a different topic.)
