[quote name='KingBollock' timestamp='1408647172' post='2532241'] If I have a 4x10 that is perfectly square (with the port on the back) and I was able to prop it up on one corner, in a diamond shape, what happens with the dispersion? And, not taking all the mucking about into account, would it be preferable to being sat flat? [/quote] I'd like to think that the single 10 would give a better dispersion, but the 2 even further apart may play about with that theory. Besides, your amp would slide off the top, or was you planning on using it as the prop?

Having it set "right" should mean you don't know when it's on, but know when you turn it off. Ideally, you want a meter to set it up. I had a lend of the boss one & gave it back after much playing about. As for position, that's up to you. Some prefer start, some the end & some in the midst of the chain.

[quote name='gsgbass' timestamp='1408218157' post='2528206'] Markbass claims the LMll, is a LMlll head without the the top panel on it. [/quote] You mean the "Combo Head II", not the LMII? If so, then you would be correct.

The LMII is a combo head (LMIII - combo head II). There's a few MarkBass amps of a similar size that you could use, or even some others fit (I've seen an Aguilar in the 2x10 combo). Edit to say, the only difference with the combo head is that it doesn't have a lid on top, so to use the LMII, you have to remove the lid (it's a flat plate on top, you don't remove the sides).

The smoking ban only relates to lit tobacco, so don't use tobacco in your smoke machine. Smoke machines don't set off alarms unless you use an extreme amount in a confined space. If you use a decent fluid, they have no smell or have any effect on people other than visual, though if the fluid has glycol in it, then it could affect some people with asthma. Fog or mist machines are usually the safest option. If a venue asks you not to use one & you really want to, then ask them the reasons why not. Google is your friend when it comes to finding out more. It's then down to which kind of smoke/fog/mist you make & what you use.

[quote name='Baronoli' timestamp='1407883773' post='2525129'] Should I have opted for the 4 Ohms then, do you think? I didn't want to limit my expansion options when browsing! [/quote] Nope. The extra couple of DB from the 4 ohm version isn't worth heating your amp up for.

It should be plenty loud enough, but that depends on the efficiency of the cab & if your guitarists are musicians or muppets. Watts don't make decibels. If the 8 ohm version ain't loud enough, then the 4 ohm one wouldn't be either.

[quote name='Guinness21' timestamp='1407776080' post='2523899'] Thanks for the advice Yeah think it's either the b3, or the boss limiter enhance, tuner and bass overdrive. [/quote] Try the pedals before buying. I made the mistake of thinking that I needed a compressor & whereas I used compression in the studio, never liked using a compressor pedal live.

The SR1000 has been my main bass for over 20 years & fitted in with everything I've played starting with metal, through various forms of rock, then to folk & jazz & finishing on a bit of electronica. Although I've given up playing bass, it's the only bit of gear that I'm not selling.

Best advice is to get a multi fx unit until you know what pedals you're gonna use. After you get used to which fx does what & what ones you like/need, it'll save you spending money on light up bricks.

I thought sails were triangle (or even square), not cone shaped.

Parallel gets my vote. I used my Bass Murf to split the signal. The good thing about the Murf is that it's splitting frequencies too, so if any fx are sucking lows, you can retain the lows on a channel. It makes a good overdrive too.

[quote name='Dad3353' timestamp='1407252852' post='2518815'] The experts and pundits will rip into this, I don't doubt, but, for my tuppence-worth, I think it's the impedance change that gives the extra watts (and so volume...). It will only be really applicable to ss amps, as you intimate; valve amps won't give more power per se, but the better dispersion will give a better 'spread' of the spl generated. An ss amp rated at 200w into 8 ohm, and 350w into 4 ohm will be able to get louder with 2 x 8 ohm cabs (and so 350w...) compared to with only one (with only 200w available...). The difference will only be a couple of db, though. [/quote] This would be right if you're using identical cabs. But if not, then it can vary greatly. An efficient single 8Ω cab (e.g. my Markbass 2x10) could be very much louder than two not very efficient cabs (e.g. my 2 old Marshall 1x15s at 4Ω). Having 1 efficient cab has many benefits. Having 2 gives you even more db if needed. It's not so much about how many watts there are, but what a cab can do with the signal provided.

He makes sense. No point buying pedals & find nothing in the setlist uses them.

+1 Save your pennies a little longer. As for cabs, either go for the 8x10 or 2 4x10s. For loud guitar bands, you'd be better with 2 2x10s or 2x12s stacked vertically (better dispersion & easier to carry).

The downside of adding a 4x10 is the 4 drivers are getting 1/2 of what the other 2 are. I'd be in favour of another 2x10 & stacking them vertically for a consistent sound. A 15 with a 2x10 does mean unpredictable results. Sometimes good, sometimes not so good.
