I am posting to ask the most basic of questions. I am an 5-string electric player, recently transitioned from electric upright. To date, I've been using the same amp setup I used with my electric upright: a GK-MB150S combo with an additional external GK 112BMX speaker. With my last band, the setup worked fine: super-portable, loud enough as is for small clubs, and for larger venues I could direct out from the GK into the band's very good PA, using the GK as a monitor. However, I have left that band and am planning to join another, but I am concerned that without a good PA to hook into, my current setup won't cut it. I'd like to upgrade to something with more power that could hold its own in a large club. I'd also like something that would allow me to take full advantage of the B string. For flexibility, I'm inclined toward a head & cab setup rather than a combo, and ideally I'd like to find something that will fit in my Jetta and won't destroy my back hauling it around. Reliability is also important to me. I'm not looking to go broke on this purchase, but I don't want to have to upgrade in a year or 2 either -- right now I'm hoping I can get what I need for $1200 or less. I don't really know where to begin here. Is there a good "standard" setup I should be looking at / trying -- a sort of benchmark against which other systems are measured? Is there a website where I can get solid info on amp buying? Any and all advice greatly appreciated.
