I've been doing a lot of amp research this summer and it's getting pretty hectic. My budget is from $400-500CDN (either used or new) I've looked at brands from Ampeg to cheap ones like Behringer and noticed you get what you paid for. The next amplifier I want is something that can last me a few years, even if I drop it because I do a lot of travelling. As for durability, I'm attracted to SWR's Workingman series and the Yorkville XM and XS. As for portability, the Fender Bassman 100 owns all in weight, but after careful consideration, I rather have something solid and 25lbs seems to be on the sissy side. That aside, Fender was never really noticed for their amps anyway, just their guitars which I love. This has come down to the SWR Workingman's 12 (USED) versus the Yorkville XM100C (NEW). Obviously, there is no comparison and the WM's 12 has every edge on the Yorkville, but the only problem is it is $610 CDN which is way over my budget and I can't get those extra dollars. Therefore, I must get a used one which is $400, but I'm kind of paranoid with used equipment. Is it reliable? On the other hand, the Yorkville XM100C is $445 CDN and is purely brand new. I've noticed SWR has a wonderful reputation in bass amplifiers, and if I had that extra cash I'd buy the new WM's 12 without hesitation. The problem is, I can't go over my budget, because my parents are getting pretty annoyed with me spending all this money on bass equipment. I play for worship which is usually around 200-300 people. I currently use a Yorkville 50watts and it is fine for worship and slight rock. What should I upgrade to? Please feel free to suggest any other amps within the $400-500CDN budget, but try to comment on the WM's12 and XM100C. Thanks!
