rivera mini rockrec - handles up to 300 watt as a dummy load (in 4 or 16 ohm settings, only 150 watts in 8 ohms), DI output, clean or speaker emulated options, and a headphone out. Could be used for silent practice, recording, or pass through to a cab. Not an attenuator though.
um, a same-tone + extra features + 3/4 volume spare head would be a bad thing to have.instead of having two amp heads..

Whait wat?
I put my V 4-b through an SVT 212 in a separate room and ran the DI plus an SM57 about 3 feet in front of the cab. Dimed the volume, bass at 3pm, mids (800k) at 1 and treb at 1:30. Tone was great.
Yeah saw this one but seems like it might not do either job ideally. It’s fixed attenuation and would think the RNDI is better DI.
Anyone used a Dr. Z Air Brake? Looks exactly the ticket for the attenuator. Coupled with the RNDI should cover all the bases.
Starting to push the cost of a PF-50T though although the above would be a solution that'd work in the studio or a gig instead of having two amp heads..
The Aracom I mentioned earlier provides variable attenuation and should be fine with the power of the V4B...The Aracom is not cheap either, so I agree A PF-20T or PF-50T might be a good idea.

Looks like the job but you’re right, pretty expensive and seems hard to find in the UK
blankets. Moving blankets work well.No bad thing and definitely an option. Just looking at the best way to use the V-4B first
Looks decent - seems the balanced DI is speaker emulation only and there’s only an unbalanced line out without it? Would need another DI too if so and no attenuator’s a bit of a drawback
Unfortunately, none of the common, relatively inexpensive attenuators that I am aware of will handle a cranked V4B. The Aracom will and the Two Notes Torpedo Reload will, but they cost as much as a used V4B. Both provide reactive loads and both are relatively expensive.
As @Jim C suggested in post #35, you could probably built a resistive dummy load for relatively low cost. I found these 500W resistors available in 4Ohms or 8Ohms.

They are available in the US on Amazon.Com from this vendor.

From the manual on their website if you have the emulation set to bypass with the switch on the front then the XLR DI is "filtered but flat." I'm not sure what that's supposed to mean. I think I'd want to hear the difference before buying something like this. I'm with you in thinking that it's weird that it's not a direct send, but maybe just part of taking the speaker level signal down to balance line level?
If you went the DI and dummy load route I would probably use a Countryman Type 85 as a speaker level DI and then your choice of dummy load. Weber has attenuators up to 200 watts. Maybe a Palmer PDI or [Invalid or Expired Link Removed], or the SPL Reducer.
I have a Fryette Power Station. Good for this kind of thing when you want to capture the tone of the speaker, specially for bass. Most will tell you to use a DI, but I think I understand where you are coming from.
But the Aracom or Ox or the Fryette are not cheap, just be aware The engineer of a recent project ( I did not play but went to listen) liked how those old Hammond Organ speakers sounded, so he patched the output from a cranked Marshall bass spec head to my Fryette into the Hammond M3 speaker and miced it. He was going for a certain vintage sound. Then into a passive Leslie which was spec'd for guitar. You can't get that sound out of a DI however hard you try.
The Fryette looks amazing, around the same price as the PF-50T and would almost perfectly complement the V-4B. Would be great in the studio and live. Can you use the balanced DI without the attenuation and still get full volume out of the V-4B/212?
The PS2 or current version will do that. Link Removed
Here' what you have in the back. Amp in is from you other amp speaker outs
1. LINE IN – This input will accept signal from any line level source, such as a preamp, amplifier line out, effects processor, pedal preamp or iPhone. Virtually any device that you want to amplify to listening level through a speaker cabinet can be connected here.
2. LINE OUT – This is a frequency compensated output that takes the signal from the load amplifier’s speaker output plugged into the Power Station Amp In jack and makes it available to drive any external device, such as a mixer, recording input, computer recording interface, power amplifier or signal processor. Use this feature to send your onstage sound to an external processor and then to FOH, an onstage powered monitor or a “wet” only amp/effect/speaker system.
3. FX SEND – Low impedance effects send jack for use with external effects processor. This connection is post AMP IN and LINE IN, so any effect connected here will be inserted between your load amplifier or external preamp and the Power Station internal tube power amp.
4. FX RETURN – High impedance effects return jack for use with external effects processor. As with the FX SEND, this connection is post AMP IN and LINE IN, so any effect connected here will be inserted between your load amplifier or external preamp and the Power Station internal power amp.
5. FX LEVEL – This sets the signal level inside the loop. Use the HI position for line level (+4 to 0dB) devices. Use the LO position for guitar level devices (-10 to -20dB) such as pedal delays, etc. In LO mode you can even plug your guitar, bass, acoustic instrument pickup or keyboard directly in here for a great clean/jazz tube amplified sound.
6. LINE OUT XLR – Transformer isolated, balanced line output of signal coming from amplifier connected to Amp In.
7. LOW PASS FILTER – Slightly reduces high frequencies (5K and up) to help smooth out cranked amp tone when recording direct. This filter also affects signal coming out of speaker outputs. Most of the time you will leave this in the OUT position.
8. AMP IN – Connect the speaker output from the amplifier that you want to attenuate or boost - the load amplifier - here. Set the Impedance Select switch to the desired setting to match your amplifier. The total power handling capacity of the reactive load is as follows: Amp In (Max Continuous): 200W @ 2, 4 & 16 Ohms. 150W @ 8 Ohms
Just some quick notes on this as someone who wanted a wide-grain power tube distortion at low volume. I was essentially chasing Al Cisneros' tone on the first few Om records without buying multiple Matamp heads or needing to play at planet-smashing volumes. All I found was that any shortcut will negatively affect your tone.
- most attenuators suck. Sure, they let you crank your tube amp at bedroom volumes, but they also kill all the richness of the distortion. To be fair, I haven't tried some of the truly expensive units that also act as speaker simulators like the Palmer units, but all the <$500 ones I tried were tone sucks. This includes the Rivera, Mesa, Dr. Z and Marshall variations.
- the reason I think they suck is that they just can't replicate the reactive loading of a speaker being pushed hard, and so don't get all that cool note 'bloom' that makes loud tubes sound so good. Weber has tried to address this by putting a speaker motor in their attenuators, and while it is definitely the best I've heard, it's still not transparent.
- well designed iso-cabs are a great solution for guitar, but I have yet to see one that works well for bass. Doesn't mean they don't exist, though...
- the closest I came to a satisfying low-volume power tube distortion is the SWR Interstellar Overdrive preamp. It uses a 12AX7 preamp and two EL84 power tubes to make a 5 W amp that you can tap into. It works best run through a speaker for the reasons listed above (there's a resistor inside, but again, without a speaker, the tone is lifeless). 5 W gets surprisingly loud, but it's still somehat sociable.
- don't underestimate the importance of string interaction with the amp. Playing in front of a loud amp messes with the strings in all sorts of cool ways, and ultimately results in my favourite tube distortion tones
Any of these attenuators work with an SVT-CL, or is that just too much juice at 300W? Not sure I'll need one, but options are nice.
