The favorite jazz guitar amp, super lightweight and powerful, has an effects section
2 channels and you can plug a mike into it

Not made anymore. They were about $800 new and seems like used ones are $600ish if you can find one
here's the manual if you want to know more about it

These are hard to find. This one has had very little use so grab it while you can
Price firm for now so I don't respond to offers
thanks
