Well I have had my first all tube rig The Jaguar 200 bass head and Jaguar 410 cab now for 4 gigs and hours of rehearsals . I am loving this bass rig . i have been playing bass for many years and have plaid thru quite a few different set ups and still have a few that I will keep but I am absolutely loving the all tube goodness of this amp and the 410 cab sounds great as well . I am real happy I went this route , there are a bunch of real nice tube rigs out there. I like the fact that I can talk to the builder of this beast when ever I need to. Great customer service and just real nice guys . After using the micro heads and lighter cabs I was a little concerned about the weight thing but this set up is real easy to get around , its not massive or overly heavy. if your thinking about taking the tube plunge I would highly recommend this company Jaguar Amplification.
