    Hi! Cool website, you got here.
    I’m repairing Bassman 135 export version (with voltage selector) these days, so I’m able give a little update:
    It uses 5A slow fuse(s). The speaker jacks are >4R each.
    Greetings from Berlin

    I used one of these as my primary amp for many years, driving 2 15s in separate cabs.  Matching GrooveTubes installed, it sounded best when loud, and then it had tremendous punch.  Never could equal an SVT though, but I owned the Fender and couldn’t afford the SVT!

    Good work!

    Could you add a bassman 100 schematic? The Bassman 135 is translinear, while the 100 isn’t according to the bassman 100 schematic (wasn’t allowed to attache it unfortunatly).

    Also, could you check the weights listed above, they seem to be too heavy for the heads.

    I own a mint ’78 Bassman 135, and this is by far the best vintage all-tube bass amp Fender has ever made.  It rocks for bass precisely for the same reason that it sucks for guitar – it is deep, clean power that doesn’t break up or distort.  You’ll try a lot a pedal combos to get what this head delivers with every tone control set in the middle, plus you have the option to jumper the second jack on the bass input channel over into the first jack on the normal channel for even more power and more tone options.  Another unique feature is that you can run either one or two 4-ohm cabs using the speaker and extension speaker jacks in the back, or just one 8-ohm cab from the extension speaker jack alone.  It even has a line out for recording.  I have played Hartke, SWR, Genz Benz, Behringer, and a ’66 Blackface Bassman head, and this 135 is my final choice.  It’s a little-known gem!

      The Bassman 100 and 135 were long-time favorites of punk-rock bands such as Sex Pistols and The Ramones. Glen Matlock purchased his Bassman 100 for £99 in the mid-70s.

    Hello, sorry but I don’t know much about any of this, my husband owns what is called a Bassman 100 silverface Fender amp, he has had it since before we got married, it is all original parts, and has a bunch of tubes in back it is still in wonderful working order, I do know this because he plays it every other night it seems. I was trying to determine how much it is worth as we are insuring our household items and I am trying to make a list of all valuables to put in a fireproof lock box in case anything ever happens. Does any one here have any idea of what something like this is valued at?

    I have a 1976 Bassman 135 is the ex speaker jack 8 ohm’s???
    This would make getting a new 4×10 so much easier

      Hello, the Bassman 135 is a Min. 4 ohm load, as spec’d by Fender, which means you can run both Jacks to 8 ohm cabs.

    A friend of mine has a 1971 Bassman head, there are no stickers or name plates on it any more and we are wanting to know what the impedance rating would be on the head? He is looking to get a 1×12 or 2×12 cabinet to go with it and need this info. Thanks!

    Looks like this site might be able to give me some answers

    I’m trying to restore and bring back to original specs, my 135 Bassman head. The tone controls, either need a cleaning or will have to be replaced, I get allot of static noise when it turn them up or down. If I choose to replace them, can you supply, or do I have to go back to Fender itself. Also, can you explain how it remove the guts from the wood casing. I’d also like to put new hardware amp handle, and metal trim and screws. If I choose to try and clean, how should I go about it, blowing it out, or some type of cleaner, in my mind, it’s not the answer, unless you have suggestions.

    1975 Fender Bassman for sale with original paperwork (including wiring schematic). It is in great working condition and looks great too!

    What was the original price of a Bassmaster 135 in 1980, cab price too, if you know it.

    Does anyone know the origins tubes ( valves ) on a bassman Silverface 100 ?
    I read RCA in preamp and Genelec in power … I think that he meant Genalex .
    Someone could tell me if these brands ? or what else… ( not an expresso please 😉 )
