What model is it?

I have just been reading an 11 year old thread on Talkbass about this very problem. Markbass and others including the Music Tribe group (Behringer, Bugera, TC Electronic, TC Helicon and more) will only give service manuals or circuit diagrams (schematics to our friends over the pond) to authorised Service Centres. Now there is a nasty rumour that class D amps and SMPS power supplies cannot be fixed. They are harder but this is bullshine. Even my 70 years old eyes can see surface mount components and remove and replace them without a great deal of trouble. So I just made the decision to avoid MB and Music Tribe in future. Small problem here in that I have a Bugera Amp but that will soon be relegated to spare. I used to work for Panasonic UK and you could buy a Service Manual for a few pounds. Anyone not just an Authorised Service Centre.

Every cloud has a Hi Ho

Actually no one is a no one.

According to Duke Le Jeune, a respected designer of bass cabinets, cone rock only occurs if the port is directly behind, but off centre, to the driver. In one of the threads in Talkbass he goes into detail about he got, and solved the problem of cone rock, with the help of Eminence's technical department. This is opinion. Corner ports are a type of slot port and they break several of the conventions. Firstly as @Phil Starrhas already mentioned, @steviehas demonstrated to me and @Phil Starrthat a single large round port is better than several small ones*. There is no good reason to suspect that this is not true of multiple corner ports. So why do people use slot or triangular/corner ports. Firstly they act as bracing and secondly they negate the need for an expensive moulded port**. Remember that the wood that creates the slot or corner port is effectively an offcut of the main cabinet panels or a much cheaper material. *This was why the Mk3 version of the BC112 cabinet had one large port instead of four on the MK1. ** A part costing £1 at manufacture will probably end up £3-4 on retail price.

All my life I have been a no one until Basschat gave me a badge. Keep the badges.

I think you should find the ELF enough with two cabs but it might struggle with a single cab.

Looking very good.

Don't sand it. Put the port in the freezer, it will contract, then slip it in the hole and as it heats up it will form a tight fit.

Discussions about ports seem to be contentious so here goes. While a corner facing rear port in subwoofers may have a higher/different output a moved closed to the corner, it is a matter of taste as to whether it is better or not. In my experience of playing pubs and clubs in the UK, a rear firing port makes it much harder to get a balanced sound when placed close to a wall or in a corner.

On the Basschat BC112 MK3 the energy from the port really is trouser flapping but I suspect that is something I can feel rrather than what most people could hear.

This puts into words exactly what I was thinking, Nothin' fancy, just a solid foundation for Billy Gibbons to work over. However that in itself is a gift, I know how hard it is to keep it simple, even when a song is just root and fifth, I struggle not to put a fill in. RIP Dusty.

I have only been on the periphery of @stevieand @Phil Starr's designs so I cannot make definitive comments* however that one thing I have learnt is that you cannot design a cabinet purely by modelling and that the traditional "rules of thumbs" similarly should be used for guidance. One thing you can be sure of is that the designs that are published are rigorously tested and measured then gigged to ensure that they meet the original design criteria. Of course there are small compromises, there is always a little more that can be gained by making the box bigger, a more expensive driver but in many cases the extra is not worth the extra. * I do lay claim to the phrase "squeezing the balloon" when describing how changing any on parameter of a design affects many others>

It was a light hearted comment that started the thread but some serious points have come out. Not least that religious organisations are not covered by the same laws and rules that the rest of us do. I won't go on but so many of the bad things that go on in the world start with religion and I could not be the hypocrite to play in a worship band.

I wonder if that was the one that was stolen from our rehearsal space 50 years ago.

Whoopee. Two Gigs without a conversion.

Howl can I join?

Of course being a total PED, Fender Japan was a ghost company for a number of Japanese factories. So buying a Japanese Fender is not really buying a Fender. In my opinion you could do worse than try a G&L.

It seems to me that the main areas of gigging these days is with worship bands. Do all the musicians "believe"?

Its Ok for you, we did not have gold stars at our school. This is the first time I have got a gold star.

If you look elsewhere you will find GR disciples everywhere on the Amps and Cabs forum.

Just innxase anyone is looking to build this, I have two of the 12CVM2 drivers for sale at £40 they have both had between 50-60 hours use. Reasomfor sale? Downsizing.

I have never bought from them but the attitude of one member of staff was not what I expect and made me question their "advice".

I agree about the esoteric caps.
