[quote name='Opticaleye' timestamp='1460109315' post='3022616'] A strange choice of cabs to compare. Discontinued apples vs fresh oranges maybe? I'd have liked to see the comparison against any of BF's current competitors like Berg, Vanderkley, Fearless, TKS and Genzler etc. if specs are to be compared. This choice seems engineered to reach a particular conclusion. [/quote]Or maybe they were just what was to hand,

[quote name='Bobthedog' timestamp='1460063018' post='3022347'] Yup, that is the one. Obviously not as independent as I thought on the basis he is a BF endorsed artist. I am still happy with my BF Big Twin II on order, however. [/quote]He is clearly not independent but apart from two things, his tests are valid. Firstly SM57 is far from ideal as s measurement mic. Secondly we have to take his word that all settings are the same. However he is trying to do things properly.

[quote name='Passinwind' timestamp='1460045841' post='3022077'] And after another week of burnt fingers and colorful language, today just might afford a first listen. I spent pretty much all day yesterday troubleshooting omissions and wiring errors, but at least I now have a test jig and a method for doing mods or repairs in the future. There are a few odds and ends in this pic that will need cleaning up eventually, but of course that's a never ending thing with DIY builds anyway. [/quote] Since I first tried those blue Powercon I loved them. They just feel professional. Are you only using one speakon?

[quote name='colgraff' timestamp='1458865044' post='3011766'] AKG wireless mics. I have a twin pair which share a receiver. Channel 70 mics, rock solid signal and no interference. [/quote]I looked at the WSM 40s and was told they were the way to go by one dealer but the quoted range is 50 metres and I need something over 60.

I would gladly buy two Stevie but finances do not really permit at the moment.

[quote name='stevie' timestamp='1459518262' post='3017358'] There's a certain satisfaction to be had from using a circle jig to cut out a perfect hole with a router, but the only time I ever bother is when I want to recess the speaker. Otherwise, I take the easy way out and use the jigsaw. Nobody ever sees the hole anyway! [/quote]A jigsaw can be quite accurate if you use the proper wood blade, that is the really skinny one. The wider flatter blades resist turning.

[quote name='TrevorR' timestamp='1444509065' post='2883805'] I've read this comment a lot on forums and it really doesn't make sense to me from a physics and engineering point of view. A bass is a much more complex system than just a wire oscillating between two fixed points being picked up by a magnet and wire coil. The vibrations within the body are so much a part of the finer timbre of the bass. When the string vibrates those vibrations are also transmitted into the body at the bridge and nut. Those will then resonate through the body and influence the movement of all the strings by transmitting vibrations back into them through the nut and bridge. That won't change the fundamental sound of the string (basically down to the string and pickups/electronics) but it will certainly have a marked effect on the complex vibration patterns in the string. This will, therefore affect the timbre of the string. Now, the body vibrations will be affected by a whole range of factors - shape of body and neck, materials of the body and neck, the material and construction of the bridge and nut, the neck/body join etc etc etc... Hence the differences between different woods in a similar/identical bass design or switching from set to bolt-on to thru neck design. Some resonances will have a dampening effect others an additive effect so these things may affect other physical characteristics such as sustain etc. Now that may sound far fetched and trying to blind with science gobbledygook but don't under estimate the effects that these sympathetic vibrations and resonances can have on the complex vibrations of the string. Here's a subtle example. The housing of the clock mechanism isn't moving but one of the weights picks up the vibrations from the mechanism and the pendulum and starts to move in sympathy with it... [media]http://youtu.be/_aILyKUm4IE[/media] Here's a rather more well known and dramatic example of sympathetic resonance gone bad... Ironically, it's in a bridge... [media]http://www.youtube.com/watch?v=3mclp9QmCGs[/media] So, will it change the fundamental of any note? Probably not but differences can and will affect the sound/timbre in noticable ways. [/quote]This is degenerating into a Tonewood debate. You are right that the materials have some affect on how the instrument sound but it is small on solid body bass.

[quote name='discreet' timestamp='1459762104' post='3019204'] Quite, but once someone has decided to take a dislike to something (for whatever arcane reason) they will say anything negative they can think of. After all, if you've never used a Barefaced cab in anger (and I'm pretty sure that most of the detractors have not) what else is there to say? The other reason could be that people genuinely just don't like the look of them and won't buy one because of that. But there are more than a few on this forum who listen with their eyes and won't consider one of the best bass cabs currently available because 'they don't look right'. Having said that, I'd be reluctant to play a bass I didn't like the look of even if it were perfect in every other way, so maybe there's something in it. But then a bass cab isn't a bass - as you say it's a black, rectangular box! What's not to like?? [/quote]Just to continue the silliness, its a cuboid actually

[quote name='Marty Forrer' timestamp='1459720378' post='3019021'] Don't cheap out on the drivers. Dave Greenboy chose the Kappalites for a reason, and he designed the cab specifically to suit those drivers. Any other driver will not give the same results. Also, use only the crossover from Speaker Hardware that is specified. These crossovers have been designed to handle a lot of power and give a very smooth transition. I built a fEARful 12/6 exactly to spec, and it's the most amazing sounding cab I have ever played through, and I've been through a LOT of cabs. If you cheap out, you will regret it. [/quote]There is not a lot of difference in the real world performance of the Beyma SM212 and the Emmy Kappalites. The main difference will be the characteristic Emminence peak in the 2K region. If you want it flat the Beyma is probably a better choice, especially as he is building one of BFM's Simplex cabinets, not a Greenboy design.

[quote name='highwayman' timestamp='1458948440' post='3012434'] Coming from messing with the guitar (but finding the bass is much more "me"!), I get the impression that Marshall's not much of a player when it comes to the low end? Blackstar too? [/quote]I have heard seen in print that one of the ~Trace designers is now at Backstair and have heard, almost from the horses mouth, that the Blackstar Bass Range is in development.

[quote name='Marvin' timestamp='1459173741' post='3014083'] As someone who came back to playing about 7 years ago, Marshall's problem seemed to be they just didn't seem interested. It wasn't gear I even considered buying when I came back to playing. They were, at that time, producing heavy, unreliable and unappealing amps and cabinets. Others were producing more appealing gear at similar or better prices. They suffer from being regarded as a guitar amp manufacturer and to some extent the bass range being an after thought. Even now there seems to be little effort in getting EDEN 'out there'. It's a great brand with a good reputation and you can barely find it in the UK [/quote]Eden has appeared in both my local stores this year so it seems Marshll are pushing the brand.

The problem is that everyone needs something different from a cab and whilst in the early days BF were great HiFi cabs, the new additions with the 10s mean they can do the lot. TKS also get a lot of love as do many of the Boutique US makers. The main thing about Barefaced is that they put their money where their mouth ( or is that port ) is with their sale or return policy.

Beyma SM212 Group buy. So far we have a total of Chienmortbb X 1 Phil Starr X 2 6V6. X 1 Any more for anymore?

Once we have the design sorted and drawn with instructions, are we going to do a group buy on the drivers?

I am not sure but I guess the use something like the old GB7 tuners from Gotoh. The GB7 is no longer made but a good replacements can be had fro Warwick at Thomann,

It is that difference in weight/density that makes a mockery of the whole "tone wood" debate. It is the density of the wood that adds a tiny amount to the sound not the actual species.

[quote name='icastle' timestamp='1458937747' post='3012332'] That's the way dual pots come. [/quote]no I have a dual pot from OMEG that has two different values.

The bass tha Rhys shows seems to correspond to the wiring diagram posted at the start of the thread. It should be easy to put it back to stock wiring but you may be left with a spare hole.

I have bought loads of irons over the years but keep going back to the Antex. One of mine is like trigger's broom, New element new tips, only the handle is original but it must be 40 years old.

Already registered!

OK Have checked things out and I like the LD Systems and the Alto (same group as Numark BTW). The Alto quotes range as 100M and that is very good but seems to need to be ordered everywhere and seems out of stock. I have to admit if I were buying I would probably go for the Alto. The Sennheisers now on eBay are really overpriced (for us anyway). We have decided to wait until the end of the season (end April) and get some new ones in, and do some testing on a sale or return basis. I will report back then.

[quote name='Bigwan' timestamp='1455907040' post='2983590'] Yup, there's a thumpinator right there! The filter responses for that circuit aren't ideal, but close enough for the purpose. [/quote]You do need more than 12dB/ octave for thump elimination.

[quote name='Grangur' timestamp='1458713653' post='3010024'] As far as I can see, it would work. The only modification would be drilling the holes for the screw on the other side of the hole for the tuning post. If I were you I'd fit one, without drilling the fixing screw hole and see how it goes, even if you can't get full tension, you'll see if it fits. [/quote]Yes I should have thought of that. I will try it and see what happens Thanks.

I cannot see how you chose what value each pot is unless yo choose a value and it is the same for both?

You beat me to it Charlie, stared writing this last night but fell asleep. There is a clone of the Cornish. Known as the Fairy Dust, there are Veroboard/stripboard layouts for this as well as a PCB kit (excluding enclosure) available from MKelec.com. Cost inc shopping would be about £15 from the USA.
