WoT's video review! Handbox R-400 bass amplifier

Mine has the slanted vents on the front with a purple light behind. I agree with everything you said about this amp. I had been using class D amps for some years, and going back to this A/B design with its big toroidal transformer and very simple eq system was like putting on a comfy old pair of slippers. I even took it apart, because I'm an inveterate tinkerer, to see what it looked like inside. I tell you, it is magic. Every solder join, every heat-shrunk terminal, every component is meticulous and top shelf. Leszek is a magician.

Yep - he's a proper craftsman... just incredible for the money.

He refuses to outsource to the far east, 'cos he wants to be personally involved at every stage. Long may it continue.

I would have liked a full gain and drive run inside the review. Maybe it's not your usual tone, but it could have been interesting and informative. Anyway, thanks for the effort, man. Great playing and talking.

Thanks!

I'll do one when I get a chance. You're right, it isn't my usual tone... can you give me an example of something?

hi, just dime the gain knob and push the drive button in, let's see what happens to the tone. The R400 seems capable of an outstanding clean tube tone, but with lots of complexity in the midrange. I really like this. And i may add that a colourful clean tone is not achievable with my Walkabout with ease, The Mesa is all about driven tone, from slightly to filthy. If I lower the gain knob on the Walkabout the tone just deadens. Just to clarify, the Mesa Walkabout is the "tone in my head" more or less, and I absolutely love it. I just wanted to check the versatility of the Handbox R400. Is it capable of some sort of grit or grind? Your Maruszczyks are more than capable to push the front end of a tube stage.

Oh, it does driven tone - as much as you like. I'll do a quick vid to give you an idea...

OK.. does this answer your question?

(Recorded at [i]very[/i] low volume as the kids are in bed...!)

That's horrible. The clean tone is lovely though.

There are two things that put me off these amps - firstly, I'd prefer solid-state throughout, no valves. Secondly, I'd prefer it if it didn't get so dirty.

These seem to be super amps at a bargain price.

Well...it should be heard by real. Maybe tweaking it a bit, but this quick demo gives me the sensation that:
It can do dirt...sounding so so
It can do a slight breakup very well

To me it seems that the R400 does a good job in that pushed tube albeit clean tone that is not perceived as actual distortion.this is the tone I love and use with the Mesa (solved the muddy tone issues with two Tungsol 12ax7, the amp changed face, dramatically, much cleaner and transparent), gain up to the point that the preamp starts to fatten up and add tube harmonics but without actual distortion or burp. Also, the actual clean tone of the r400 seems more intriguing and rich sounding. On the contrary, the Mesa excels in the drive tone, that can be tweaked to sound like a full tube reminishent of a pushed SVT.

All in all, a very interesting amp, at a bargain price, reassurely built with traditional power stage.

I'm following these amps with great interest, but waiting for the WB 100 too...hope that the Handbox owner can find more time for amp development

It got that dirty because I literally dimed the gain to the max, as Sratas asked. You can see the position of the gain dial each time, and the drive is engaged adding another 6db. There's lots of clean tone, which is why I love the amp so much.

The tubes? Again, that's what makes it what is - if iit had an SS front end, it wouldn't really be for me.

Wot is an enthusiast, he has found its tone in the r400, but this doesn't mean his reviews and samples are less useful. In fact, he did a lot of work and his method of showing tones is one of the best I know.
I really appreciate his work. Keep on man, and thanks for all.

Yes, I saw that. I'm not one for that much dirt, but, like yourself I think, prefer a cleaner sound.

Interesting amps and being hand-built from discrete components, something I'm very happy to see on the market in this throw-away age. Thanks for the video. Excellent work.

Frank.

Thanks, Frank.

I'd never use it fuzzy like in the example earlier, but a bit of hair around the edges is nice, especially as the mids are so rich. And, of course, completely clean is an option - and how I usually run it.

Only just caught up on this thread altho i read the initial post at the time.

WOT :- i would have to say your way of demo'ing the amp is perfect for me. I like the way you keep the bass relatively simple throughout that allows me to identify the subtle changes in amp settings.
I would hope you continue to demo gear in similar fashion.
I don't want to see a demo of how great a bassist thinks he is. Its more about what the amp can do for a traditional style of playing or a particular song style.

Excellent reviews and i am quite interested in one of the R400 versions.
I found the all tube version had a nice tube tone but not as much variation from the EQ. I find that with most of the all-tube amps.
I prefer the hybrid tube with SS back end for reliability.

Altho its a year after you last posted on this i was wondering how much of the tone is the amp and how much from the TKS cab. I've not used a TKS cab but they do appear very popular recently.

Ah, thanks Dave. Much appreciated.

TBH, I haven't used the R-400 with anything other than my TKS, so I can't really comment. FWIW, my S212 and S112 don't have a distinctive 'TKS' tone IMO. They just sound like classic bass cabs...

Maybe that's why they are so popular. Too many modern cabs sound a bit thin to me. I'm currently using a Berg HT322 that i bought from fellow BC'er Karlfer few yrs back now. Its bloomin heavy but just sounds fantastic at any volume. Also have an Orange rig which sounds good but again heavy.

After a couple of years' service, one of the preamp valves threw the towel in last week so I took the opportunity to replace them all.

 It was pretty straightforward - little bit of effort is involved in getting the head out of the case, but nothing too taxing.

It's all ready to go for tomorrow night 🙂

Hey gang

Yep, I've been bleating on about these fantastic heads for a while now (more here), but I've finally got around to doing a video review.

Hopefully I don't ramble on too much...

I’m just looking into these as I think they would tick several of my boxes. They look and sound great.

Cracking review, many thanks.
