For those who helped me out about the 1966 Fender Bassman the other week, thanks a lot. To the guy who asked for a NAD if I get it, this is for you!



1966 Fender Bassman Blackface. All stock, no mods on the inside. Honestly, this is my first vintage amp, and I had no idea what to expect. The videos on YouTube aren't very good quality and almost all of them have been modded. The guy I bought it from was an old lad, and had it for decades in his rehearsal room. For the most part the amp is mint, the silver cloth has turned a brownish color, and there is a slight tear in one place of the cloth. He had Eminence Swamp Thangs in the cab, but they were brand new and drove the price up, so he stuck in the old Fender speakers that came in (made by Jensen). I figured I might as well get those and start from there, besides he only put those in because the Fenders were a little too squaky as he was using it as a bass amp.






Like I said, I only had a bit of an idea of what to expect from the demos on YouTube, and from people talking about them on forums. I seen enough enthusiasm about them that I figured I'd bite the bullet and go for it, after all it was likely an improvement from my HRD.

Boy was I right. I never experienced an amp that produces "punch" like this one. Thankfully my apartment complex is filled with fellow university partiers, cause this thing is loud. I haven't had a chance to fully crank it, I got it to about 6 before I felt bad for the people below me. However, like most Fenders, it takes pedals beautifully. I haven't found a great tone with my MXR Wylde Overdrive (it took me a year to find a sweet spot with my HRD), but I use a pedal called the Jekyll & Hyde which essentially gives me the sound I'm looking for at a lower volume (amazing dirt pedal).

I hope to eventually get soundclips on here and YouTube. I want it to be properly mic'd though so if anyone else is looking at these and wants a good idea of what a stock 66 Bassman sounds like. I am considering some of the capicitor mods that give it more of a AA864 circuit sound, since I heard they're relatively easy and completely reveresable. Also, if anyone has any experience with these, if I were to replace the speakers, what would you reccomend. I heard this head goes well with a Marshall cab filled with Celestions, would those be a good fit in the fender 2x12? Let me know if you have any ideas!



Cheers guys!

Very nice.

I paid 1200, but it only really costed me 700 cause he took my HRD as credit. The guy did me a favour for sure, since prices in Canada can get blown pretty out of proportion. He also drove 5 hours to drop it off for me since I have no car while I'm away. Just felt it was time to move on and get rid of some gear haha, gave me a big lecture to take care of it. Dude tears it up too.

Not sure I want to touch the tubes, he just got those redone and biased and what not, and frankly don't know much about them . What sound would I expect if I did?

That is one hell of story.

Consider yourself lucky. That is a once in a life time deal there.

I wouldn't worry too much about the tubes. Best thing to do is just make sure the tubes are nice and snug in there sockets and anytime you do mess with them spray some contact cleaner on the tube pins while you work them in and out. Dioxit.

I have a blog in my profile on biasing power tubes even though you don't need to worry about that it might give you some helpful tips. I will also post a vid on changing preamp tubes. Some preamp tubes are bright and some are dark. Some are awesome and some are crap.

Here is the vid:

that is an incredibly sick amp. one hell of a deal too.

if you do change the speakers then you should keep the stock ones so you can put it back to original spec.

i am kinda biased toward old sounding speakers, i would get some kinda weber. if you are mainly using clean tones i'd recommend a JBL D-120 clone. i love d the sound of the D-120 in my old '69 twin
https://taweber.powweb.com/weber/cali12f.htm

you can do a jenson C12N style speaker. this may be the speaker that is actually in there, but most likely you have utahs or oxfords.
https://taweber.powweb.com/weber/12f150.htm

these speaker are like the ones in the tweed deluxes (jenson C12Q)
https://taweber.powweb.com/weber/12f125a.htm

something like an EV would also go nice in there (you can find used one for much cheaper than a new real EVM-12L). SRV loved this speaker.

i have a set of old celestion clones he has (silver bell and blue dog). these things are killer, they area clone of one of the first two models of celestions that were released in very early marshalls and voxes (respectively). i mix them in one 2x12, incredibly great sounding.
https://taweber.powweb.com/weber/blue12f.htm
https://taweber.powweb.com/weber/silver12f.htm

you can also probably do something like a celestion G12M-25 greenback or the newer high powered greenback and possibly mix it with a G12H-30. that is some old school tone. greenbacks were a favorite of many guitar player like EVH and jimi, etc.
http://celestion.com/product/25/heritage_series_g12h55/

http://celestion.com/product/141/g12h75_creamback/
http://celestion.com/product/123/g12m65_creamback/

those are all just different flavors of a greenback. some have more low end than others.

mixing just about any of these speakers would be all win too.

You can swap preamp tubes around as much as you like. It's just plug and play, no rebiasing or anything. A 12AX7 will give it bit more grit, Marshall it up a bit. Try it, you may like it.

That's a lot of help! And I didn't realize you could take them out, I may consider that since an old Marshall tone sounds appetizing to me!

Here's the speakers in them. They have been reconed (I think that's the term, I've heard it called redoped a few times but that might be a rural thing).



An old marshall inspired tone would probably suit my needs. I have a gross range of music but i'm a big fan of guys like Springsteen, Frusciante, Slash, Angus Young, etc. They can be quite different but generally it's warm cleans and a good crunch (in my ears anyways). I get it pretty good right now, but there's always room for improvement! Thanks for all the different speakers.

The single biggest difference between a Bassman and a JTM45 is what's in V1, followed by speakers and lastly power tubes and output transformer.

I'll have to put the Classic T models on my to-try list. Shame the finish options there are Anachronism Gold, Nuclear Waste and Aged Clown, because in principle the plaintop is right up my alley.

Umm I'm honestly not sure whether its the AB165 or AA165. I'll check it when I get the chance

If I remember right, the only real difference between a bassman and a jtm45 is that first preamp tube. 12ay7 for bassman, 12az7 for jtm45.

Seriously sick piece of gear, very happy day.

Well, also the tone stack of course. Count the knobs.

Y'all niggas is cray. A Blackface Bassman is literally nothing like a JTM45 or Tweed. The BF Bassman is cool as hell, but it's a way different sound when cranked. Standard complement for the preamp was all 7025s (high grade 12AX7s for those of you who aren't Cath) with a 12AT7 PI.

Anyways, HNAD, OP. Throw some EVMs in that cab for killer tones.

The JTM45 was based on a 1959 Bassman. ie. a Tweed.

And you are right, the BF already has a 12AX7 in V1. I was thinking of the Tweed. Sorry bout that.

haha so I already do have a 12ax7 then. I'm getting some killer tones atm with the Jekyll & Hyde pedal. On the Hyde channel I get a serious cranked marshall vibe. Had to pump out some Appetite For Destruction for a few hours yesterday

EVM's look great but are way out of my price range for now. I heard good things about Bassman's and Vintage 30s, and they're a bit cheaper, so those are a bit more realistic.
