[TPIN] Amplified Effects

[ACHIAS1 at mchsi.com]

We just got a small amplifier for my daughter's guitar (which she thinks she's good at but isn't - as 
opposed to the sax which she is good at and thinks she isn't).

Now I'm considering playing around with miking my trumpet and playing with electronic effects like 
distortion, octave displacement etc.

Are there any devices around that I could use for this that are cheap?

Wow, wouldn't it be cool for an entire brass quintet to do this? Maybe on Gabrieli? or Praetorius? or Zappa?
