    I played a gig with my trusty ole t-funk but this band was a bit loud for the TFB420 to keep up. I'm thinking of upgrading to a louder head and the 400+ and DB750 come to mind as they would match my cab quite well.

    How do these 2 compare volume/headroom wise? How loud is the 400+ before it breaks up as I like my amps clean?

    Wow, I'm interested in this thread also! I have a DB750 coming my way and I already own a 400+. One will have to go after I A/B them and make my decision. SUBSCRIBED!

    I've played 'em both but never A/B'd 'em, but my money's going to be on the DB750, based on what I've heard hereabouts. I'm waiting with baited breath.

    I always thought that the DB750 had more useable volume. The 400+ is a monster, plenty of power on tap, but I could never focus it in the right frequencies, so basically, the DB750 is louder. I A/Bd them when I got my DB750, and I'll only be keeping my DB750, for reasons of volume, tone, and headroom. The DB750 has considerably more headroom.
  5. I used to play through a 400+. They put out some volume, but like any tube amp...they do break up. I've only had my DB750 for about 2 weeks, so I don't have a ton of experience with it. But based on what i've heard so far...the DB750 is definitely louder, and cleaner (when you need it to be).

    EDIT: The 400+ does push more low end though. But the 750 is tighter and faster, and mroe focused. The 400+ has a more weighty feel to it, with more girth...but a slower response. And it can get pretty boomy if you're not careful.

    I dunno which one is louder, but both will give you more headroom than you could possibly need. The 400+ could probabally get as loud as the 750, but it would be driven into distortion to do it.

    I've never played through a 400+, but my local bass hero... a dude that simply mesmerizes me everytime I get the chance to hear him play... uses one of these with some kind of Mesa 4 x 10", and his sound is fantastic. However, he could play through a little Pignose and make it sound awesome, too...:D...

    ...I've gone through a few amps in my 30+ years, and I've finally found my primary workhorse... DB750...;)

    I look at this fact as more of a added benifit that the 400+ has, than a short-coming.
    I dont think of the higher volume levels as becoming more distorted, I think of them as making my amp sound better....:smug:

    When I want a clean tone out of my 400+/NV610, I stick to using a reasonable preamp level, no pulls, near flat tone settings and only use channel one's input.
    I can then bring the master way up and stay very clean at stupid-high volume levels.

    While I've not done a side-byside A/B, I have tons of time with the 400+, and a fair amount of time with the 750. Overall voume and headroom?...I believe this is a fistfight the DB750 is gonna win.
