    There have been discussions about rack-mounting sleeved amps in the past - The general consensus was that assuming the amp was about the right size, you could mount it under an upside-down rack-mounted shelf, which would then provide the missing sides and top. David

    It is an 8 ohm cab. The bottom end is covered by an Eminence Delta 12LF rated at 500 watts, the mid-range is covered by an Eminence Alpha 8 rated at 125 watts and the top end is covered by an Eminence APT50 rated at 35 watts so you could use it with amplifiers up to 5-600 watts without worrying about it melting. As always, your tone settings will determine whether the the speaker starts to fart before the amp starts to clip. I used to use it in a church worship band with a 200w/8ohm Hartke amp, and it was rarely above 1/3 volume. It is more efficient than your average box. Let me know if you need any more information, or better still, come over and try it out. David

    [b]Update 11 March - now £80 posted[/b] Update 28 February - now £90 posted I bought these to try and cure a Warwick neck-dive problem, but they were not enough - I even tried putting lead in the control cavity before I gave up and sold it on. These were on the bass for a couple of days, and have been in the box ever since. They are the HB6Y design, with a 3/8 inch shaft and the Y shaped head: not the Fender clover type. They are also the shiny chrome version: not the cheaper satin chrome. They are set up as three on top and two underneath a right-handed headstock, but can be easily dismantled and turned around if you need 4+1 or 2+3 These will cost you £135 if bought new from Bass Direct. You can have mine for £80 posted to a UK address. David

    [b]Updated 08 April - now sold[/b] Updated 11 March - price reduced to £160 Updated 28 February - price reduced to £180 Updated 23 February If you are thinking of building an Omni 12, this is a no-brainer - it is fully working with non-neo drivers for less than the cost of the parts, and if you are thinking of building this version of the Omni 12 but with the recommended neo driver, you can throw away the Delta 12LF, and fit your own neo bass driver and you are getting all the parts and a completed box for about the cost of the parts and a sheet of ply. BFM Omni 12 Original design - £160 Eminence Delta 12 LF, Eminence Alpha 8MR and Eminence APT 200. 24 inches wide by 28 inches tall by 15 inches deep. Crossover by Falcon Electronics: inductors 1.0 or 1.25mm diameter wire – high quality capacitors. Cabinet finish ‘Protectacote’ truck-bed liner I also have a 2U amp sleeve and wheeled trolley that match the speaker cab - they are now optional extras 1) Matching sleeve for amp- £15 Suits 19 inch 2U designs Has a filler plate beside the rack mount bringing the total width to 24 inches. 2) Separate wheeled plate for transport. - £10 Transport arrangements are negotiable – I can meet you within a reasonable traveling radius of Warrington, or I can arrange a courier at your cost. Thanks for looking David A youtube video of the Omni 12 and amp and wheels, but powered by the Markbass head on the rig next to it. The video camera was on a tripod about 20 feet away, and you can see it shake on the low notes about 30 seconds in to the recording. [media]http://www.youtube.com/watch?v=N7VJH27HgSw[/media].

    The cab is sized for the particular speaker, so you may be lucky, but probably wo'nt be. Download a free speaker box design program (WinISD is fairly good), select the specific model of Eminence driver that you have, and it will give you the right size of box, and the right size of ports for the box and that speaker. 3/4 inch ply will make a solid and heavy box. 1/2 inch ply will make a lighter box, but you have to put a 2-3 inch deep shelf about every 8 inches on each side to make sure it does not flex. If you search on DIY cabs, BFM cabs etc you will find plenty of advice on what to do next. David

    Looking at your photographs, I can't see anything obviously wrong - The original star earth with resistor/capacitor 'modules' is supposed to stop most problems, but didn't. Your current earthing wires ought to work, and I am not convinced that switching earths as well should be necessary Your earlier posts refer to both a buzz and a hum, so the first thing we need to be clear about is which problem we are trying to solve. Deep bass-tone hum is mains 50Hz or 100Hz, and we need to keep it out. A buzz is more likely to be caused by a digital piece of kit, and it can often be suppressed by putting a load on it. Take a resistor of about 1K ohms and put it across the output connections of the pod, and see if that gets rid of the buzz. If it does make a difference, see if it still works on the output of your box, reducing the input impedance of your amp. Since each preamp is a buffer between your instrument and your amp, this should have no impact on your tone. If one resistor on the output works, that is what to do - if it does not, try one resistor per preamp output. If you still have a hum problem, my next step would be to try and find out where it is coming from: Start with the obvious - check that all your jack to jacks are correctly connected, to make sure that you have not lost an earth connection somewhere. Next, connect in preamps until you get hum, then disconnect and reconnect in a different order to see if it is always that socket that gives problems, or always that preamp that gives problems - you have probably already done this. Next, check whether you get the hum with one preamp powered up and the others powered down, but connected - this may identify one preamp as the culprit. If that does not provide some clues, then I'm afraid anything else I suggest would be guesswork. David

    Walker, Going back to the original switchbox build thread, the capacitor&resistor combination marked 'A' is designed to damp down hum loops so they are not a problem. I'd suggest putting one of those in one of your signal earth paths and then checking each preamp in turn on that input/output, to see if it still hums or buzzes. If it seems to help, then put more of them in, until all the circuits that hum are connected to earth via these modules - hopefully, that should clear it. In your previous post, you ask if it is dangerous to disconnect earths - no, providing that they are signal earths, and nothing to do with mains earths. You also mentioned joining earths (serial) - if you are joining them all together, that is parallel. Joining them like daisy chains would be serial. David

    I am not a luthier, so I may be wrong on this, but my understanding is that a paint finish is more than skin deep, so you can sand it and then refinish, but you cannot sand it then oil it - the oil cannot get into the wood because of the paint residue that is already there. Can any one confirm / correct my recollections? David

    I'll take a guess that the Ampeg input earth, or one of the preamp earths, was not too good, possibly due to tarnish, or cheap cable/plugs or whatever. Connecting everything together has improved the poor earth, resulting in less hum. As I said, just a guess. David
