I was merely pointing it out as I don't think there is currently any

other way to do it.

Connecting the guitar directly to the phone with a simple plug adapter

would probably sound meh.

Unless Google wants to add support for external USB sound cards to Android? ;)

Sounds cool, I recently bought one of those beasts (

http://www.fractalaudio.com/products-fa-axefx.html ), and I think it's

amazing, hands down the best amp modeling I've ever heard (and amazing

effects too!) demos are here

http://www.fractalaudio.com/experience.html
It also does model the power stage section (power tubes->output

transformer<->cabinet interaction) and exposes many parameters to the

user, like tubes bias, negative feedback amount (if any), sag, B+

filtering/capacitance, even speaker distortion etc.

I'd be happy to compare your plug-ins to the Axe-FX ;)
I would personally prefer desktop LV2 versions of your plug-ins, they

could always be ported later to Android if it's going to be worth the

effort.

And I would prefer GPL'ed plug-ins and be willing to donate, I don't

think there are many options right now on Linux, I dislike rakarrack

and guitar_ix, and find CAPS* so so.

Can't help you there, sorry. I have a cheap entry level HTC Tattoo and

it's slow as molasses. Haven't even attempted to install any audio

related apps. It might be feasible on higher end droid phones though

provided the audio API allows it, I just don't know. I think there has

been a recent discussion about realtime audio apps on Android on LAU

if I am not mistaken, you might want to search for it.
Sorry for the OT.
Ciao,
