Years ago I explored this avenue and drew a blank however I do remember reading that a Bassworld member used a 2U rack tray upside down. He drilled 4 holes in the tray to pick-up on the captive nuts in the amp chassis where the sleeve screws normally go. Hope this helps.

[quote name='jbarks' post='1104651' date='Jan 27 2011, 01:09 AM']Used a line/instrument cable with an SVT-3 Pro for the longest time when I had to cannibalise some rack equipment—no problems there. Almost every sound engineer I've spoken to (and the guy who recorded my album, who has some pretty high end stuff in his studio) all said it was fine and that no, my amp wouldn't explode.[/quote] Just because you/they do it doesn't mean that its correct or advisable. I asked Klotz about using instrument cable for speakers and their technical guru told me: "The power loss with conductor cross-section of 0.22 sq mm (centre core of typical instrument cable) is dramatically high and even may result in a cable fire". "Also the reduced damping factor of the system results in worse properties of sound." "Furthermore twisted speaker cores have better EMC and lower EMI."

Put 10-amps down an instrument cable and it will melt. If you don't believe me try running your electric kettle on an instrument cable and watch it melt. Lord Valve recommends 12-gauge cable. 12-gauge is the closest american equivalent to 4-sq.mm. SAFETY WARNING - DO NOT USE YOUR INSTRUMENT CABLE TO POWER A KETTLE.

[quote name='markstuk' post='1103500' date='Jan 26 2011, 12:41 PM']I use 2.5mm two core mains cable for my speaker cable (rated at 30A).. It's cheap at about 80p a metre and can cope with modern amp current loads without heating up too much.. OBBM uses 2.5 mm Klotz cable in his speaker cables as well.. Why have a powerful amp and restrict the amount of current it can flow to your cab?[/quote] Correction: I use 4-sq.mm. 224 strand cable for bass amp leads, 2.5-sq.mm. for guitars. The 4-sq.mm. has a very low resistance which keeps the damping factor high and allows tighter control of the speaker driver especially near its resonant frequency. The centre conductor of an instrument cable typically has a cross-sectional area of 0.22-sq.mm. which gives a higher resistance and a lower damping factor.

Bought an Lakland DD pickguard from Lee. Exactly as described, very well packaged and quickly sent. Having recently made him a custom cable it was nice to be able to reciprocate. Top man.

Makes mine look like a wreck.

That is in amazingly good condition. What's the back like?

[quote name='flyfisher' post='1094911' date='Jan 19 2011, 11:01 AM']What you could do is re-wire the internal speakers so that they are in series. This would give an 8 ohm load. Then add another speaker socket (wired in parallel with the amp output) into which you could then plug an external 8 ohm speaker, giving an overall load of 4 ohms to the amp.[/quote] How do you work that out then?

The B210 manual states : "Speaker Specs: (2) 10", 100w, 8 ohm , 2" voice coil dia., 30oz. magnet." So it's already down to the minimum impedance. I recommend Plan B (not the singer) and change it for something more pokey.

If the head/power amp only has a single power stage then using 2 cables is fine but quite unnecessary if you use correct sized cables. It certainly won't anable you to extract more power from the amp. That is a function of the speaker impedance. Where you have to be careful is if you are using a separate dual channel /stereo power amp or a head with 2 power amps. In that case you should in NO WAY connect both speaker outputs to a single cabinet. It will be magic smoke time for sure and an expensive repair bill. In this case you should use the bridged output into the correct impedance speaker. This is typically double the impedance that you can connect to the individual channels. If you are unsure what type of amp you have then don't do it.

I assume your talking about a solid-state stereo amp in which case it's fine to run without a load. Valve amps on the other hand must have a load matched to the output transformer setting.

For the past 7 years I've been very happy with a Nordstrand in my Status necked SR5.

Thanks Jack. Lots of memories there. When I first started work in 1964 I used to commute into Waterloo Station, get the tube to Tottenham Court Road and then go and peer into Selmer's shop before continuing on to Islington. I really fancied a Verithin bass but unfortunately I could never afford one. The house band bass player at one of our local jams still plays a Futurama, in preference to his really nice jazz.. Everyone agrees that it sounds sh*t.

We seem to have 2 parallel threads on this same bass. Can't we combine them? FYI The SR5 was intoduced in about 1988. Dual Humbucker SR5 was intoduced at NAMM July 2005. Details of models and serial numbers [url="http://myweb.ecomplanet.com/TOWN8019/mycustompage0029.htm"]here[/url] . Pictures and serial number would certainly be very helpful.

[quote name='risingson' post='1085965' date='Jan 11 2011, 07:50 PM']I've seen some horrible attempts to fit a second neck humbucker to a Stingray 4 posted somewhere on the internet (something about Stingrays having a cavity that easily allows this modification, but I'm skeptical). The dual humbucker Stingrays I'm almost positive were not around in the 90's though.[/quote] The SR5 was intoduced in about 1988. Dual Humbucker SR5 was intoduced at NAMM July 2005.

Six years ago I toured with a guitarist who put on a new set of strings every night. He'd been doing it for years, since the 60s, and it had become a pre-gig ritual. He managed just fine with his fingers.

[quote name='Chris2112' post='1082784' date='Jan 8 2011, 11:59 PM']Is it the first ACG bass with the fibre optic LEDs?[/quote] To the best of my knowledge, yes.

[quote name='Chris2112' post='1082770' date='Jan 8 2011, 11:50 PM']And another rare ACG in this thread - mine is the first Harlot Singlecut! There have been a couple more made since, it's a design that works excellently as a singlecut.[/quote] There are a few other headless Harlots, but not to his spec and this is certainly the only one with fibre-optics so far.

[quote name='Roland Rock' post='1082753' date='Jan 8 2011, 11:37 PM']Is that an ebony top?[/quote] Yes.

My headless ACG Harlot is certainly rare as it's the only one like it.

Another quick check would be to do the "forbidden" and connect the Markbass cab to the Ashdown with a short instrument lead just to verify that the outputs work. Is the Speakon a 2-pole or 4-pole? If the latter is it wired correctly?
