Like I said, it depends. If you don't care about blowing speakers or destroying transformers, go ahead without checking the impedance.

Check the impedance, there's no other way besides possibly blowing speakers. You're just checking a number. If you're worried you can come back and tell us the number and we'll say if it's okay.

The 66 Bassman head has a 4 Ohm output transformer (125A13A). Apparently you can also safely run a single 8 Ohm load off one of its parallel-wired outputs (and lose some output), but the optimal situation would be a single 4 Ohm load, or a pair of 8 Ohm loads. I'd be willing to bet that the matching cab with original speakers and wiring would probably be impedance-matched to the head, but without knowing how it's wired or what's in it, it's hard to say for sure. The CR120 apparently wants to be hooked up to one or two 16 Ohm loads, or a single 8 Ohm load. You do NOT want to hook an amp up to a cab with lower than recommended impedance, that will likely damage the output transformer on the amp, if not more. Given that the stock blackface Bassman cab is almost certainly lower impedance than your CR120 head, I would definitely not hook it up without first checking the impedance to see how it's really going to load your amp.

Yes...but you may have to make it work. If you don't have a meter, you'll want to pop the back off and see what's inside, along with how it's wired. The individual speakers should have the impedance somewhere on them, even it's just a factory stamp next to some other giberish. Look for the Ω symbol if you don't see the word "ohm."

As for how they're wired, remember that parallel HALVES the impedance (most common in a 212) and series ADDS the impedance. So two 8 ohm speakers in parallel is a 4 ohm load, and in series is a 16 ohm load. How do you tell?



In parallel, the input wire USUALLY goes to the (+) and (-) on one speaker, and those are connected to the (+) and (-) on the next speaker. There are some other goofy ways to achieve it, but this is what you'll almost always see in a 212.

In series, the (+) and (-) from the input are connected to the terminals on TWO speakers, with another wire connecting the remaining terminals.

Of course, this is assuming both speakers are connected and working. If one is removed from a parallel circuit by being disconnected or dying, the remaining speaker will run at its original impedance. In a series circuit, the whole thing will shut down.

It looks like the CR120 has a minimum of 8 ohms... so if your cabinet is wired at 4 in parallel, you should rewire it to run at 16 in series (or unplug one of the speakers). If it's already at 8, you're golden.

THE TAIL THAT BURNS TWICE AS BRIGHT...




I successfully transplanted the Champ and added a 3-band tone stack. Sounds pretty good and the Jensen C10Q is a pretty good match.

I was originally gonna have a switch turn the tone stack on and off but then realized that this requires me to either have a second volume pot for that or have it be separate from the volume and always max. I did have a spare pot around that would have worked but in the end decided that one knob operation is kinda pretty loving dumb so I just took the switch out and that's what that little bit of electrical tape in the front is covering. Also I forgot to get proper fasteners to attach the chassis cover so it's also held on with electrical tape so that the plate and chassis actually stay together so I don't misplace the loving plate before I get the fasteners.

Actually removing the old speaker from that cabinet was the hardest part because the nuts were sort of epoxied on there so I had to slowly twist them to break past where the epoxy was and also there was some corrosion and it was a pain in my butt.

Nice! Is this a new production C10Q?

Did you wire the FMV tone stack in the typical fender way, capacitor to the junction of the top and bottom wipers of the two adjacent pots, or capacitor to wiper way?

It's a new production, and I went standard Fender tone stack wiring. The whole set up has a nice slightly compressed clean tone to my ears.

E: supposedly the speaker will break in and sound ~very vintage~ according to internet bluesdads but even now it sounds pretty good

Sica-made Jensens are painfully ice-picky and brittle, and take forever to break-in. I like the Blackbird series of speakers they're doing now though.

I have a bizarre request for anyone that knows about schematics and stuff (I do not!). Basically, I have a hunch that the "Thick" circuit for the Night Train is the same as the "Normal" channel for the AC15 or 30. Just because comparing the two they have the same pre-amp breakup point and react so similarly. The "Bright" channel stays clean for days and only starts breaking up right at the end of the gain level, but I swear the Thick and Normal circuits are the same, especially since they both have two controls plus the Tonecut to control them (AC15 has "Volume/MV" and NT has "Gain/MV" so basically the same thing).

I'm not going anywhere with this, I just have a suspicion that they're either the same, or really dang close. It's bothering me so I was wondering if anyone could give me closure!

The story I've heard is that it is quite literally just the tone circuit taken out of the signal path. The reason it breaks up sooner is that the signal isn't being filtered through the variety of pots, caps, and resistors that make up the tone stack.

I've also heard that the Night Train is based off of the "normal circuit" in a AC15; but considering how the bright it can sound I wouldn't be surprised if there are some changes. But most of this I can't remember where I heard this from, and I've never looked at the circuit of a Night Train so I would take all of this with a generous helping of salt.


Edit: nvm, I forgot you had the bigger version. I am basing all of this on the 15w version; I don't really know much about it's big brother.

No no, that's applicable. I was working on the assumption that the Thick mode was the Normal circuit from an AC15, and the bright channel was that with added EQ options. It likely differs but that was the guess I was making, just because of the similarities.

Can someone give me a quick comparison and offer a recommendation between a Peavey Valveking 112 combo and a Peavey Super 40 XXX combo? And in lieu of either Peavey, would a Blackstar HT5R 1x12 be a better buy?

The Valveking is excellent for cleans. For a while, there was a whole community of guys in Ultimate Guitar who were obsessed with modding' the poo poo out of the Valveking combos (both the 112 and 212) to make them Metal-ready and I found it hilarious. Like, if you wanted a metal sound, why didn't you go for the 6505? The Super 40 has a bunch of functional, on-board effects that are a good bang for your buck, but don't expect too much out of them. Rhythm channel is good.

So, it depends on what you want: The Valveking is excellent for cleans but the OD can be kinda iffy (disto, OD and boost pedals do work wonders on the guy, though). The Super 40 has is more or less an all-rounder with some effects, but doesn't do one thing beyond "acceptable"or "good". Never tried that particular Blackstar, so I can't give you any tips on that.

The one I've been rocking for this tour is the Mesa Boogie Recto-Verb 25 head. Now, I know that doesn't meet your wattage needs (it can change between 10 and 25 watts at most), but the fucker can push air. I actually tried to run it through a 4x12, but that got kicked in the head for being too loud, so I've been using an Orange 2x12 closed back cabinet.

The other guitar player DOES have a Multi Amp setup and he uses a Mark V 35 head with a Zilla Fatboy 2x12 for his filthy (but pedal-free) tones and an Orange TH30 combo for cleans.

Also, our boss started playing some guitar on the second half of the tour and she started using a Soldano Astroverb head, which is a 20-watt head and I honestly do not know why, but I am getting that head from her when this tour is over because HOLY CRAP.

Ampeg Gemini would be a poor choice as it's an open back combo. I'm partial to the new Fender Rumble series for gigging for wattage to weight ratio. The built-in overdrive isn't terrible, either. If you're looking for tube maybe a used Ampeg cab and a Peavey Windsor? Would get plenty of grind.

From the standpoint of maintenance and repair I would go with the Valve King. They do have some design issues, but I don't see them as often as other Peavey tube offerings. Avoid anything Blackstar. They use surface mount micro resistors and most techs are not set up to handle SMT, so when it's out of warranty and dies you are either looking at a costly repair or an expensive doorstop.

If you can, see if you can try a Peavey Classic 30. I haven't heard the Bassbreaker yet, but I know it blows the Blues Jr out of the water. Their Delta Blues is similar, but with more speaker coverage, so it may be too much "oomph", despite technically being the same power.

I also rather like the Crate V-series, if you can find them. Leaves you with pedal money. :getin:

What kind of drive are you looking for? The model-t saturated tube type is going to be expensive and an old Fender won't really give it to you. I played a dual showman setup for a while and it was alright, but not great.

If you like the old solid state type grind it's easy enough in my opinion to get it from a pedal. The Rusty Box is very very good at that sound and then you can run it into whatever amp you got. I've got both a Rickenbacker and an old Sunn Beta Bass and would recommend the Rusty Box over the Sunn unless the amp could be found real cheap.

jwh
Jun 12, 2002

Rusty Box is great. Apparently it's the preamplifier from a Traynor TS50B, or at least, something very similar. I've used one for a long time with my bass rig which consisted of just an early eighties p-bass, a tuner, a rusty box, and an early SVT. Also sounds pretty good with guitar, too.
