Non-Ampeg Tube Amps

20160904_102903.jpeg


My Uber rare Fender Custom Shop Rumble Bass 300 amp (only 60 of these were produced) and matching Custom Shop Rumble 410 full range cab on the left and the right one is a Rumble 410 Sub.
 
I traded for a Traynor YBA 200-2 last winter. Prefer a cleaner tone, so I swapped the AX's for AT's. Been loving it! Was letting my dad use it for guitar while I used my rack with GK 1001 RB-II. I sold an SVT II Pro to buy the GK, which has since taken a back seat for the Traynor. I love my GK, but bought a guitar head for Pops to use so I could play through my Traynor.
 
Just scored a Fender Bassman 300 Pro (Sunn 300T) on EBay for ~$650 shipped!

Stoked to try it out with the new to me MAS 210 Flex Mod from Alphaman...

With my Orange Bass Terror 1000 the cabs sound great. Looking forward to hear a tube sound through them soon!

What a steal!
Ignore the naysayers. You scored a super deal on one of the best all tube amps ever made!
 
Hmmmm. Not so sure that is completely correct. Could be, just that I'm unsure.

Note that the Fender Pro 300 is the same as the Sunn 300T.

Per the manual:

Your 300T's tube compliment consists of:
• One 12AT7A Tube (part #023531), (tube location V4)
• Three 12AX7WA Tubes (part #013341) (tube locations V1 thru V3).
• Six 6550C Tubes (part #048489), (tube locations V5 thru V10).

Rectifier is SS and likely because of the graphic EQ, there is some SS circuitry in there too.

Yeah, Foxen always jumps in to try to make some dogmatic point that any tube amp that has ANYTHING in the signal path that isnt tube driven somehow negates the sacred "tube amp" doctrine. So most tube amps arent tube amps then.
My Ashdown bta 400 is actually a hybrid with a solid state preamp with a tube power section. The fender 300 pro is full on tube amp glory with a tube preamp mated to a tube power section. Oh yeah...it has modern features. Welcome to the Reformation! You dont have to worship in latin anymore!

A while ago I had a Mesa 400 (not the plus). I never really got to use it to its fullest potential so I can't say I really liked it. During my first time around as a musician I didn't really know much about gear, so I didn't have basses, pedals, or cabs that could really give me the tone I wanted. I had to replace the Power switch and the DI was shot. I only tried to push it into over drive a few times, but it wouldn't go.
Because of that experience I've always thought tube heads were sort of overrated. I also hate retro looking stuff, and it seems like tube heads are stuck in 1979.

As far as other brands not yet mentioned, there is also Orange, Verellen, and Dunwich Amplification makes tube amps, but I don't know if they are "bass" heads per se.
Dunwich and Verellen have both made bass amps. Dunwich's are mainly custom builds, while Verellen has the Meat Smoke which is a regular model of theirs. Orange, of course, has the AD200B.

The new Mesa heads are fairly "modern" looking, since I know you don't dig the vintage aesthetic. Same with Laney's Nexus Tube and Peavey's VB-3.

Man, I'm not gonna knock bass guitar tube amps and I'm not gonna knock nor promote solid state amps but I am going to say that most high quality solid state bass guitar amps are full frequency range of 20 hz to 20,000 hz.

How about tube amps? Especially, the old ancient bass tube amps from the 70s and older. Most of these amp have very simple and crude amp designs.

Yeah, they pull off excellent over-drive sounds but how is their fidelity level? (I used to have a Mesa 400+ and it put out the most "nasal, honky, dominate midrange sound" and I hated it!)

As long as a solid state amp is not over-driven, it puts out clean, clear, high fidelity bass sounds and all the sizzle a slapper could ever want. If we want to put some "dirt" on the sound, there are a multitude of effects pedals and some with preamp tubes. And, there are also SS amps with tubes in the preamp section for over-drive through the gain knob.

So, what is my point? Yeah! What is the fidelity range of these old ancient bass guitar tube amps that are supposed to be the "holy grail" of bass sound?
How is that not knocking tube amps?

As for midrangey tone, that often works really well in the mix.

When it comes to fidelity, the cabs that tube amps are often paired with might be affecting your perception. Old cabs were extremely attenuated on both the low end and high end. Play a Reeves 225, or even a Mesa 400, through a hi-fi cab and the sound will probably be hi-fi.

That said, those of us who like overdrive usually don't want hi-fi sound. In my experience, using overdrive, I prefer that the cab not go much above 5khz, because anything above that will just sound like a tin can full of bees with overdrive. Also, down in the extremely low range, even though I tune down to BEAD in some bands I'm in, I don't find 20hz to be a useful frequency. Speakers can't generally produce it very well, and that whole sub low range is really stepping all over the kick drum's sonic turf. Most of the time the sound engineer is going to high-pass at no lower than 40-50hz. Usually higher.

With slap, I actually prefer less sizzle. I like the old school slap sounds, not the modern super-crisp ones.

Additionally, while I like preamp drive, it sounds different from power amp distortion. Most solid state amps I've tried do not sound good with their power amps distorting, whereas every tube amp I've tried does.

If I am playing an open E string or the challenging open B on a 5er and my amp's fidelity on the low end is like 50 hz -6 db.....................well yeah, fidelity matters 'cause my open strings are being eq-ed out by my amp's lousy low end freq range!

If I'm a "slapping sizzle freak" and my amps top end is 10,000 hz................that's not 20,000 hz!

I respectfully disagree with your remark about fidelity not being important for a bass amp. But I do agree with you that the knobs and tolex make no difference in the sound. ;)
A bass guitar has very little actual fundamental frequency on the low notes. Most of what you're hearing is actually overtones.
Beyond which, speakers generally aren't very good at producing those frequencies. And the human ear doesn't hear them particularly well.

If you are going through the PA at all, or being recorded, the person doing mixing will likely be cutting those frequencies out as well, partly to prevent masking the kick drum, as mentioned previously.

I have a couple of Telecaster Basses with the humbucker close to the neck. They produce the fundamental, in abundance. That sound is useful for some genres (reggae, dub...) but at the moment I prefer an up-front Precision tone.

The Dynacord G-2000 I posted earlier is also hybrid, with a transistor front end but I don't overdrive it appreciably so the effect of the preamp on overdrive and compression is negligible. At the volumes we play, the tubes start to saturate nicely, so I get the tone I have been looking for. The Peavey 18" is surprisingly articulate even at higher frequencies (not hi-fi of course).
 
I've been gigging with SS Trace Amps for years. Before that I used a '64 Bassman 6G6-B head I bought in 1982, that traded hands among band members. I have it back in the stable, but I don't use it anymore. I did play through a '68 Marshall Major for a while.. what a monster tone! That whetted my appetite for KT88's, and now I'm happy to be getting down with a Trace Elliot V6 :) I don't bring it for quick on, quick off festival gigs, but if we're playing a few sets, I bask in the KT88 glow.

I sold a Marshall Major head for 150.00 in 1976, every time I look at them in ebay I cry. It's not the money I lost it's just that I really wish I still had one but there is no way I'm going to pay what they go for nowadays.
 
What do you mean with "in a perfect world"?
Regarding the Basset Hound my version of perfect would be never having to play louder than that amp could comfortably handle. Never having to run straight from a day job to an evening gig using gear I don't highly prize that had to be left in a parked car all day. Never EVER saying yes to a gig that I don't care enough about to make the effort to bring my very best sounding equipment to.

Wow! Talk about quote worthy!

Its just knowing the difference between using the word 'all' or not.

hmm .. your definition would seemingly disqualify a huge percentage of the tube amps that have been mentioned, and which are considered by most/nearly all players as "tube amps"
how is having a tube pre-amp and a tube power section considered not a tube amp - just because it uses a SS rectifier in the circuit ?
seems like a fairly meaninglessly narrow definition

I don't count passive power supply components such as the rectifier as a gain stage, so it doesn't figure. That's someone else's definition, and yes it makes no sense. Its having solid state transistor gain stages that makes stuff partly transistor.

To me, it the output stage is SS powered.. then it is a SS amp, it is fueled by tubes.. it is a Tube amp.. makes no matter to me what is in the preamp section..
That is what I believe the context of this topic is based upon.

Look at your typical Marshall JCM900 guitar amp (just an example), it has a tube preamp, a tube power amp, but has SS opamp EQ stages, but is still considered a 'tube amp'.

As opposed to 'all tube', where it would need to be all tubes, rather than tube and SS. Its why the term 'all tube' exists in addition to 'tube', which generally refers to power stage only.
