'67 Fender Bassman AB165/AA864 Hybrid - the Most Versatile Amp Ever?

Note: the bass sounds off, which I've discovered was a bitrate conversion thing when saving as the final MP4. I've sorted that out for the future, but wish I could redo this one.
Like I mention in the video, I'm not thrilled with the mic placement, mostly for the higher gain stuff. But it is what it is, and this gives the idea. It's hard to wear all the hats.

The school bass amp I played through in highschool (1987-1991) was a 68 Bassman with a Fender 2x12 cabinet. I rattled the windows of the Disneyland hotel when we played in the quad. These really are great bass amps, and I say that as a bass player.

[@PsionicAudio]

Hmm, the bass that sounds great played back through my real monitors overwhelms my phone speakers. Me fix amps good. Me working on KZbin.

I just picked up a 1966 bassman head with the matching piggyback cab, all original with the exception of electrolytic caps, the cab has the original Utah Speakers. I also play the bass in the first channel and guitar in the second. I'm also an all original 1966 model so...LOL The bassman heads from the 60's have always been my favorite! I was shocked at how clean and original this one is, I've soldered on many 68 to early 70's silverface bassmans and expected a hack job on this one. It came from of all places a Guitar Center in Nashville TN...Psionic works involved??? I wonder.

I’ll take you there…. Yeah! As a lifelong bassist (with a 28 year gap from last gig till getting back to it 17 years ago) I owned a 64 blackface Bassman. You just jangled some old school memories. With a 62 Jazz Bass…… sigh…. don’t have that anymore . But I have rebuilt the bass & amp/ cab stock. Thanks for that memory

[@BadToad1963]

I'm curious what value bypass caps you went with on the normal channel. I'm rebuilding a silver face Bassman for a friend.

[@NewYorkerNomad]

More Bassman!!!

[@neilzspam]

With the SG, roughly at what volume level does it start to break up? My late Bassman head refused to get dirty. Also, can you give us the value of the bypass caps you changed to? Great channel, thanks!

[@PsionicAudio]

Thanks! Lots of very different sounding circuits sold as the "Bassman." Nothing after '69 sounds like this. I don't recall what value bypass caps I used. Probably 4.7uf though.

[@nickjamesgang]

They do Rhodes well too! Nice Spinal Tap ref :)

[@peacefulruler1]

Great sounding bass; is it a real Musicman?

[@leonardo.rafael]

Users describe “jump” to the act of plugging one jack of a guitar cable in the number 2 of one channel (as an output) and the other jack of the cable in the number 1 of the other channel (as a “return”). The guitar is plugged in the other number 1. May be it safe for the amp and the pedals to use this jump as an effect loop ?

[@justinthomas7222]

Try it & see. Worst I can see happening is overdriving the input on the 2nd channel. Crap, thanks for the idea! I'ma try that on my Showman & my 75s! Maybe my Concert even.

[@leonardo.rafael]

@@justinthomas7222 I recently read that jumping is like wiring both channels in parallel. It seems number 2 were not “outputs” as I thought, so it doesnt makes it a sort of effect loop at the end of the preamp circuit. Sorry for that.

[@justinthomas7222]

@@leonardo.rafael that's true, b8t I'm not expecting it to be. None of my amps have FX loops because I'm old school. That said, I have amps with 2 independent channels and so it can be quasi-stereo, one channel/amp dry & one wet. I don't need perfection. I just like different ways to get new sounds or get through a gig. Creativity > The "Right" Way To Do It.

[@justinthomas7222]

I will swear by the AB165 preamp. I added a tube to my Bassman 100 & I've even got a head shell & tranny set to make my AB165 that I had to sell to pay the rent... It's a pedal killer & would give a non-master Marshall a run for its money.

[@PBH74]

What would the difference be in the bass channel with 500 pF plate bypass compared to remove it completly?

[@eyedunno8462]

Chaos

[@PBH74]

@@eyedunno8462 I have tried both ways now. It was slightly brighter without bypass cap, but I preferred the 500pF bypass cap.

[@luigideluca2655]

i'm facing a huuuuge confusion trying to decide between an AA864 (with swapped 220 tranformer) and a stock AB165. found them from the same dealer at the same price. i want one mostly as a collectible amp since for live sessions i'm using multichannel amps and/or digital solution: this tempts me more in the direction of the AA864, but in terms of fun when turned on the AB165 inspires me more...HEEEEEELP :'/

[@PsionicAudio]

Play them, see which speaks to you. That’s the only answer.

[@luigideluca2655]

@@PsionicAudio in this case, i cant! a friend of mine would be able to test them, but is preatty much like 1000km away :/

That’s a first for me....they play bass pretty well....

[@marcusniemann9253]

If you had a bass pickup installed like Scott Lucas does could you run one cable into the normal jack and the other into the bass jack? kzbin.info/www/bejne/fIWtdYaPgrmlgNU

[@PsionicAudio]

If you wanted to, yes. The channels on this amp are in phase with each other.
