    I am putting up for sale one of my Mesa Bass 400 heads. I have two of these original beasts. One I kept at our practice studio loaded with 6L6's, the other is my live stage amp loaded with 6550's, so I am selling my practice 400. My band is giving up the large rehersal warehouse, and we're moving our practice into the singers' basement for a while and I'll be using my B15, so I'm not needing or have the space for two of these things for now.
    This amp was made in '87, and is in very nice shape. As you can see, it has very few scratches on it...cosmetics are very nice. The tubes in it are Sovteks and are about 2yrs old, and certainly will keep going for many years. There are no modifications done to this amp, only maintenance, and I've gone through and re-soldered the typical solder joints that were weak points from the factory.
    The Bass 400 is a tone monster...all the crushing lows and tube grit you can dish out. I absolutely love playing these because you actually 'play' the amp, not just through it. These tube amps are very responsive to your plucking hand...you ease up and deliver a round blossomy tone, and then can dig-in to deliver a bad attitude. I never had to change the eq settings when I played in a country band one night, and a metal band the next night...it's all in the hand response dynamics. And the volume is rediculously LOUD with Mesa heads. I've played countless gigs outdoor and indoor with no PA support. Yes, you can run either 6L6's or 6550's in the Bass 400. (do not confuse it with a 400+)

    I'm very interested.

    In order to replace the 6L6's with the 6550's do you have to have it biased. Or do you just need "special/matched" tubes from Mesa. What is the output wattage difference with the 6L6's verse the 6550's.

    Hey, I might want this this next week. I think I'm going to give up on the ultra-light SS heads and go back to tube power.
    I just need to sell couple of things.

    It' s got a fixed bias. So You plug them in...

    Mesa does not sell 6550's anymore and used to use Sylvanias in the 80's according Rich at Mesa.

    Not sure how much louder 6550s are than 6L6's.

    I just recently bought a 400 from Chef / TB & replaced the 6L6's with reissue Genelex KT88's.
    More bottom & top end! Not sure how much louder it is.
    But tonally there's big difference! (I use 6 F bass. )
