all tube bass amps with a graphic eq

[dnegreiro]

can you guys help me find a bass amp? I'm looking for an all tube head and it has to have either a graphic eq or it has to have great mid range control. I like to be able to have 2 mid controllers, be able to control the frequency and the Q. I liked the aquilar preamp. But i want ALL tube. It can't be more than $3000 new.

oh and i wanna use a passive bass with this

Not sure if this is high-end enough for you, but my bass player runs a late-90's FMIC/Sunn 300T all-tube bass amp, and it has a graphic EQ. Huge, nice-sounding bass amp. They don't make them anymore, but the current Fender Bassman 300 Pro looks to be the same thing.

Not to pick nits, but almost any graphic EQ section is going to have solid state circuits in it even if the rest of the amp is tube. The number of tubes you'd need to implement an all-tube graphic EQ would be kind of impractical.

[dnegreiro]

well i guess as much tube as possible... but out of curiosity, what do you mean by impractical?

A Mesa 400+ seems like the obvious choice.

there's the ampeg svt 2pro
mesa 400

+1.

Looking at the schemo for a Boss GE-7 EQ, it uses an opamp section for each filter band. So you would probably need an extra tube for at least every two EQ sliders, maybe one for each.

Op amps are used in place of inductors, and not in the signal path as you'd expect. It's possible to build an EQ with only one gain stage at the end. I think there's an API or APSI graphic EQ designed like this. It's not the most useful design, imo. (Try searching for an APSI 559 schematic) It might make a cool unique addition to a bass amp. I don't see the point in trading function just to have a tube EQ, however. It's not as if the graphic EQ in the 400+ makes it any less of a tube amp.

Then that opens the selection up a lot. You could take any tube amp that has preamp out and power amp in and plug the EQ of your choice between, be it graphic or parametric. There's even tube-flavored options in outboard EQ mostly for recording, like ART for instance.

If you like the aguilar db680 all tube pre with 2 bands of parametric, just find a db728 400watt all tube power amp to pair with it. Sure it will weigh a ton, but it will have the preamp you're looking for (my favorite preamp of all time, as a matter of fact) with a massive all tube power section.

like a 400 watt gorilla. my fav all time all tube setup. too bad they dont make the 728 anymore.

i'd go w/ the 400. just massive sounds, and the graphic EQ is incredibly handy.

but honestly, aside from the all aguilar setup, i'd just put a nice parametric eq like a speck asc in the loop of whatever tube amp you have and go from there.

i use my speck w/ my sadowsky, and its freakin' awesome the amount of tones i can pull from that combo.

The Mesa Buster Bass 200 is all tube, with graphic EQ.
No longer being made, but sometimes they pop up on the bay.
I have the head version, and it is a real tone machine for bass. I get to turn it up about half way, or a little more with the band, and that gets you into Sweet Territory, when you can get the power tubes hummin'.
Not so easily done with a 300 watt tube amp. They get too loud too fast. The 300s (SVT, 300T) do have
more girth though.

TRACE ELLIOT V6 is hands down the best all tube amp w/ the EQ section. If you don't believe me , see what bass amp powered the WHO, Sting, Eric Johnson Band, Monte Montgomery, and all of Chris Maresh's solo/studio session work.

[SoulToStrings]

I'm sorry, I meant to type V-8

Any of the V series traces are good, but the 8 is the king of tube bass tone.

I got a Fender 300PRO 300w all tube, 2 blendable chans. (OD & clean) inbuilt 2 band comp. & 10Band EQ-6x6550's = Monster!!!!

[Zim]

Trace Elliot? Older ones I think. Or go Tube Power amp, Pre amp w/ Graphic, or Pre and a graphic-old School style.

That's *just* an updated Sunn, right?
