I bought a Mesa M-Pulse 600 Venture Combo about a year ago and loved the sound - right up to the time that it fried itself big-time at a gig back in January.http://tb1.talkbasscdn.com/smilies/mecry.gif Fortunately it was still under warranty but given the time it takes to get the parts out to NZ (full new set of mosfets and new speakers) and get it sorted I didn't get it back until last month. Played my first gig with it since getting it back at the weekend but unfortunately it just aint the same amp - way down on power and the tone that I loved was gone. I rarely had to use the EQ and could set the pre-amp controls pretty much at noon and it sounded great. It might just have been the room we were in but no end of tweaking it could arrive at a decent sound. No matter what I did it sounded like an el-cheapo solid state amp with a flabby single 15 inch not the high-end combo that I had paid for.http://tb1.talkbasscdn.com/smilies/colors/mad.gif Long story short I went back to the store and it looks like they are going to replace it with an M6 Carbine Combo. It will arrive at the store tomorrow and I'll get to check it out then. In the meantime, has anyone had any experience or comments on these?
