    Hey guys, this is my first post here!
    I've been playing for 3 months, and before that, many years ago, I played the DB and electric bass for a couple years. This time around I'm having a lot more fun with it though!
    Anyways I just picked up this amp for a cool $425 off of craigslist, its a Fender bassman 215 cabinet with a 100B head. It says the head is 250 watts.
    First of all, how did I do? I really like the sound, I get a really deep, thunderous tone from it. I turn the treble and frequency pretty low and I turn the bass and mids way up. Would this head be able to take another cabinet? I was thinking about adding a 210 in there at some point.
    Also pictured is my Squier P bass, its got some years under it, but I don't know how old it is D:

    It's only 100 watts, and the speakers are guitar speakers. You'll probably outgrow it in short order, but it's fine for practice. It's not from the 60s, though, and the head isn't the tube head that originally came with that cab.
     
  3. 2x15 guitar cab? Huh - interesting

    I would question that if it weren't billfitzmaurice posting - thanks

    I think you did pretty well at that price!

    I had this exact setup as my first stack many years ago. The head can't take another cab, the 250w is the consumption rating of the amp the output is 100w. The speakers are more of a guitar speaker design compared to todays bass speakers. Use it as is and don't push it to do what it can't and you have a good rig to use until your ears tell you to move on. I played mine about a year, sold it for what I bought it for - and then bought a new Hartke stack...

    Thanks guys, I didn't know it was a guitar cabinet! Still happy with my purchase, I'll definitely buy new next time I buy a stack.

    just an FYI, your 2x15 speaker cab is a BASS CABINET (bassman 2x15) from 1967 and they ARE bass 15's (they just aren't near as heavy duty as the bass 15" speakers of today). the head is from the 80's.

    Bill refers to it as a guitar cab because it's more shallow than most bass cabs so power handling is limited as a result...also, you see more guitarists using Bassman cabs than bassists. But it is a bass cab, as that was its original intention. I've found they sound quite good at lower volumes for bass but won't take a whole buttload of power. But I still think you done good!

    Technically it may be a bass cab in name, but until the mid 70s Fender OEMs from Jensen/Utah/CTS etc. were generic 'musical instrument' drivers, and the same ones were used for both guitar and bass. They weren't the only ones, as dedicated bass drivers didn't start appearing until then, other than high end JBLs and the like.

    I had a similar rig for a number of years... sounds fantastic until you try to push too much power.

    A friend of mine had one, circa 1972, with the 100w tube head. I ended up pulling the drivers and putting them into horns. They cranked then, but it was a really big load.

    some of the fender 15's with the square ceramic magnets were very similar (if not the same) to the ones that ampeg used in their B15N's.

    One driver used in the B15N was the Jensen C15N. It was also used in the Gemini l, as well as the Bassman, and a number of electric organs. The C15N is still available as a reissue, and the specs are quite interesting, including a 73Hz Fs and 1mm xmax that we'd never consider for a moment as bass worthy today.

    yeah, they used quite a few different 15's in them. the ones that i was referring to are (one of the most common) the CTS 15's with square magnet, like this one that came in one of my '73 fender 2x15 cabs:

    I think those are what I swapped out of my friend's Bassman, but it was a bit too long ago to be sure. Those square magnets looked impressive, but they were less efficient with regards to flux density than round.
