Hi all, I've just spent a couple of hours looking through old posts so I hope no one will be too greatly offended if any of my questions are answered in the forum history. And if they are, please put up a link to them. As I'm new here, I'll fill you in a little on my situation. I have just recently finished up 5 years of study in visual art and am a weekend muso hoping to put a bit more of my time into music since having finished study. I wish to get an amp set up that is acceptable to jamming in band situations but have a very tight budget - I am not in the situation where I can save up for an extra couple of months and get something better (than what I'm looking at) as my first priority really should be saving up to go into business. Now, to the questions: 1) Behringer - For those of you who have ever owned a Behringer Ultrabass BX1200 combo or BX3000T amp - have you encountered any technical problems? How often? How significant? I have heard a friend play through a BX1200 as her first jam-worthy amp and was very impressed at the sound. I have since heard her play through a BX3000T (with a GK cab) and am also suitably impressed. Thing is - her BX1200 was in the repair shop 3 times within 8 months... she liked to play with gain and volume maxed.... I am wondering if her problems were self imposed? (Not really sure of the nature of the repairs - just that she "blew" the amp). So far, no problems with the BX3000T over 4 months. 2) Repair of amps - for everyone who has ever owned an amp - do all amps go to the repair shop sooner or later? What are common problems? Should it be viewed like a car - if you can't afford a top notch brand new car and have to buy second hand expect to have to get some repairs done over time? In the same vein - do second hand high end amps and brand new low end amps see a comparable amount of repair work? Do repairs tend to be unreasonably expensive? 3) Does anyone know of a website or other publication that explains as clearly as possible and in lay-mans' terms how to figure out what cabs and amps make a good match? I've tried to research this but always get confused over the relationship of Watts and ohms and whether it is the amp or cab that should have the higher specifications. 4) Does replacing the speaker/s in a cheap amp/cab with the equivalent to what is in a high end amp/cab considerably improve the sound? Could it be likened to putting expensive pickups on a cheap bass? Would the expense of replacing cheap speakers with expensive speakers effectively negate the savings offered by buying at the low end? Also, might upgrading the speakers be a reasonable consideration as something to do down the track if budget allows?
