    Comments about Fender Super Bassman 300W Tube Bass Head:

    I have gone through so many bass amps. Ampeg SVT. Mesa 400+, Orange Terror 1000, Tecamp Puma 900, GK1001rb2 and a few others. This is by far the best sounding head that I have played through. I was hesitant about the overdrive channel. I own and have gone through over 50 overdrive pedals and I could honestly say that the od in this amp is amongst the best Iv'e heard. It has a very useful blend knob that you could dial as much gain as you want. Or you could just use the overdrive channel's active EQ and not use the drive at all. Just two different clean tones. 2 12AX7 tubes for a pre amp and 8 power amp tubes (6x 6550's 1x12AX7 and 1x12AT7) make for a huge tone. So much power behind every note. I play in a very loud band. I use a GK Neo 4x12 and it sounds perfect. I can't say enough good things about this head. I am not even the type to write reviews, but I was compelled to ,as I am really happy with this thing. Get one, you'll be stoked.

    Comments about Fender Super Bassman 300W Tube Bass Head:

    this amp has a brilliant fender sound, if you want to play a fender amp in your band, then this is perfect;

    the point of this amp is to sack it with more cabinet wattage and rip up a medium to large venue, thus 300 watts in the head, and active cabinets for the speaker output, and you get an extremely punchy and well defined bass sound that will disseminate over a large space better or as well as any other bass guitar stack on the consumer market;

    the tube section is also stellar for the familiar commercial alt/metal/rock big distortion sound; with full blend and full gain, you can achieve a sludge metal sound with no problems, your bass will sound close to dropped guitar; but this sound is possible to achieve without spending as much; if you need the anti-biasing circuit, or 8 tubes, that's why you get this, because like I said, it's built sturdy for putting out huge wattage; when it overheats, a little warning light flashes, like what happens when the engine of your Honda Civic overheats; in other words, something you learn in an engineering 101 class you took online; there's a little thermometer;

    the cons: it's not that versatile; the dry channel eq is just ok, I need post amp compression to get the tones I wanted without it stinging my ears a little bit; the active overdrive channel is better, but I had to chain a lot of peddle compression to perk the tubes up enough to make it worthwhile; the pull filters are nice, really nice; a huge selling point; the bass pull in the active channel will give you a really gross tone;) i'd put Slovakian tunes or Russian tubes in it instead of the stock tubes, if you can;

    the balanced output is terrible for DI recording;

    so the final thoughts are these: $1800 for a amp head that will flash a little red light if it's overheating, that is built study enough to take on a stadium tour, which most people don't need; if you have a large peddle board its overkill, you'll have too much power to worry about overall, and be kind of grossed out; if your band is based on the bass, then yeah, you'd want a bigger amp than the guitar, including active cab power (why the head is only 300 watts)

    the smaller version of this might be a better investment if you just have a bass, not that much signal processing in your instrument line, or none at all, and are looking to upgrade to a tube drive sound for recording, and small venue gigging an unsigned band, then yeah...yeah;
