Lately I realized that my Peavey Mark III is lacking volume and have decided I better get a better amp. I've looked around extensively, and I have my eyes set upon Carvin. Has anyone tried their amps? I'm considering the R600, R1000 or the B1500. After reading reviews, I've concluded that people hate the tone of the R series because of the mid sweeps, and probably the overkill of tonal shaping. I'm no stranger to mid sweeps and I know very well that if used improperly, mid sweeps can make your tone horrible. I also know that mid sweeps, if used properly, can make your tone unbelievedly beatiful. I've also read that the B1500 has a "nice tone". Now, that comment can be helpful, had it told me how the tone was nice. Which amp is more versatile, the R series amps or the B series? Which amps can get over a drummer? All the amps have atleast 500 watts into 8 ohms, and I've been told that 400 watts is sufficient to overcome a drummer. However, I heard that the R series amps have a very weak volume. Also, R1000 and B1500 put out 700 watts at 8 ohms, does it constantly put out 700w or does it only put out that much power if you crank the amp? (My 8 ohm Madison 15" cab is rated at 500w RMS (1000w program) and I'm wondering if the R1000 and B1500 will damage my cab) I'm guessing my budget would be around 500 CND (I can probably spend more, but I'm considering buying another bass too, maybe a groove tool) and I'm probably going to use ebay. Are there any other amps similar to the ones mentioned that I should consider?
