| A PA will be superior to most guitar amps. Guitar amps tend to have extremely convoluted frequency response, so you will not be able to get a "clean" trumpet sound. Some of the distorted sounds may actually be attractive, but they'll vary from amp to amp. Also, the distortion will be hard to control when you get to performance levels. You may get a good sound in your living room, but when you try to increase the volume on a gig, it'll sound entirely different.
I review amps for Just Jazz Guitar. If you want a natural sounding amp, then an Acoustic Image Clarus amp driving a Raezer's Edge Extended Range cab will get you there; however, you can buy a PA for less money.
If you persist in trying to use a guitar amp, then I think the Peavey Transtube Bandit is the best amp for a low budget attempt at this kind of thing. It's got a reasonable clean sound, good headroom and its "street price" is around $300.
