Blonde Bassman questions

You can use either input for guitar

did someone say transitional Bassman? This one has the BF-style filter cap layout (2-70uf/350v in series) Them transitional Fenders are like a "box O' chocolates, you don't know what you'll get"

 

Like Russ said, I use both - the only consideration for me is that the bass channel doesn't take pedals very well. Overall though, I think I use the bass channel more.

 

I have an almost identical amp. It's from June of '64 and is a 6G6-B. It has many of the AA-864 changes like yours. From what I've heard they gradually changed things over. It wasn't like they built 6G6-B's and then the next day changed to the AA-864 tube chart and circuit. I use the bass channel pretty much exclusively.

You should keep an eye on ebay. Sometimes you see people selling the original transformers. It would be worth it to get the right old one back in that amp.

 

I'd really like to hear what some of you guys are hearing in these Blonde Bassmans. You know forever, and ever that was my dream amp, a Blonde Bassman, with tube recto and a presence knob, then I got one, a 1961 6G6...

AND IT SUCKED!!!!

I had it gone through, caps replaced, checked out totally top to bottom, and that Bass channel was so thin, BRIGHT (*see ice pick in ear) and REEDY. It was terrible. The normal channel had an okay clean sound, but nothing to get excited about. I never heard a nice growl, all I heard was a lot of flatulence when you wound the volume up, and a lot of ice pick in the forehead on the bass channel. I lost $1000 when I sold that amp, and I still wonder, was it just that amp? I know my tech, and he is a master at old Fenders, I even had another tech verify the circuit, just because I wanted so bad to love and keep that amp.

So if anyone near Iowa has one, let me know, cause I'd love to play through another one and hear what I'm missing. Some people claim they are as ballsy as an old 50 watt Plexi. I've heard plenty of good 50 watt Plexi's, but that Blonde Bassman I had, plus two that have surfaced at guitar shops, just sounded like rat poo to me.

 

From mine, I get rich, gorgeous, grand piano-like cleans and really sweet natural breakup when pushed. It hangs right alongside my other amps as having stunning tone. I can't imagine parting with it.

My '62 is not 100% vintage — Ben Fargen restored it last year right after I bought it because someone had modded the bass channel, so that plays a part. I also put in all NOS tubes to original spec — Tung Sol 5881's and RCA 7025's — so I did everything I could to make this as close to an original as possible. It paid off.

Total cost: $1400. Easily as good as $3500 boutique amps.

 

Hey Bill,
I've got a '63 that I've built into a 2x12" combo using Weber C12N's. I primarilly use the normal channel. Live I run the volume at 1:00, treble at 2:00, Bass at 11:00 and the presence at 3-4:00. The Bass channel is a great sound and actually has more gain on tap. It is a strange arrangement with the treble control on the Bass channel. The gain dramatically increases when you wind up the treble. The Bass channel with the volume and treble dimed is a great, although very bright sound. I'll use it occasionally with my LP bridge pickup with the tone rolled back.
Clarity with balls is the way I like to describe this amp. It is a very present, in-your-face type of tone with a fat, tight low end and clear high end. I'm in the middle of doing an album with my band and I'm printing the Bassman with the volume on 6-10 on every guitar track. I combine it with other amps, and it always fattens up the mix. For overdriven slide stuff I am using the Bassman on 10 combined with a Mesa Blue Angel pushed with a Landgraff OD. It is a mighty fine sound.

Thanks for the topic Bill. Enjoy your amp. You got a good one.
Here's a demo of one of my tunes that I recorded in my home studio. All of the guitar tracks are my '57 RI LP Custom with Timbuckers straight into the Bassman with the normal channel dimed.

Here's my 66' Bassman that was modded by David Allen. It was the AB-165 circuitry and I sent it to David to mod it to AA-864 circuitry. Normal side is the AA-864 circuitry and the Bass side is modded to Tweed Bassman/Marshall Plexi circuitry. The tone on both channels is anything but thin and the Bass side on either the Tweed or Plexi setting will start to growl and overdrive at about 5. I realize that this is not the 62' or 63' circuitry your talking about,but I just can't see any of these bassman sounding thin and farty unless something is wrong .My cab is a repro cab loaded with 2 12' Weber Californias. The head really sounds huge and big running through this cab. I have 2 Vibroluxes and have run the 66' head through the 2 x 10 configuration and it sounds so georgeous, that I'd like to get another Bassman head and put it into a 2x10 openback cab.

 

does anyone build a clone of a blonde bassman?

 

Brian Gerhard at TopHat Amps modded a '67 BF Bassman to 6G6-B blonde Bassman specs. This amp sounds incredible!!

This pic shows the added presence control, which was mounted in one of the two speaker out jacks so as to avoid drilling any new holes in the chassis:

Very Good Stuff!!!!! :RoCkIn

 

I've got a Jan 64 Blonde Bassman. The guitar channel is definitely the way I go. Many do a minor mod to use the Bass channel, but I'm leaving mine stock.

I just had the 2x12 cab recovered, since the tolex was really ratty, but my Bassman's tolex is in great shape, and the amp appears to have been very well cared for. I love its tone.

btw, I had Vintage Jon (Jon Bessent) of Tonecraft Amp Repair in Austin, to completely tune it up a few months ago. It was well worth the investment.

I hope you enjoy yours.
