I would like to buy an electric guitar, keyboard, and amp, for about 2000 dollars altogether, suggestions, please
you said rockers, so without knowing any more specifics, here ya go Epiphone Les Paul standard - $400 Line 6 Spider II 212 Combo - $400 (guitar amp with effects) Yamaha MO6 - $1200 (great keyboard, but if you need to be able to get a keyboard amp as well) Kurzweil KME-61 - $700 Roland KC-350 - $500 (keyboard amp with multiple inputs) and if you'll be buying a keyboard amp, you might want to buy the Line 6 PODXT Live instead of the spider. You can just plug it into the keyboard amp and it has way more options and more control than the spider.
I was faced with exactly this about six months ago. I settled for a Roland GW-7 keyboard, a Yamaha Stagepas 300 PA system and a good well used Squier Telecaster. The GW-7 is not the best workstation in the world as the facilities are a bit limited, but the basic sounds, particularly guitars and bass are very good and it's very user friendly. As I don't use automatics the bells and whistles don't interest me. The stagepas is a 300W mini-system with the amp built in to the back of one speaker and a leads compartment in the back of the other. It has 4 channels with reverb and it is good for home use or small gigs. The Tele is just plain and simple, good sound and robust. Now the really good bit : The advantage of this system is that it is all very light. The keyboard is only 7 kilos and the PA is so light can be moved in one hit with a well designed handle on each speaker. I bought this set-up in Muziek Produktief in Ibbenburen in Germany and even with stands, seat and additional leads I still had a couple of hundred in change out of 2000 Euros. Hope this helps
