As long as no drinks go on it and there's no monkey business I don't mind sharing my rig. The cab is stupidly overrated for the head so there's no danger of blowing stuff up. I haven't had a problem with people taking the mick, on the whole they've been most grateful and it's all handshakes and "thanks very much". Sometimes I've even got compliments about my rig, sometimes you get to geek out a bit with someone. I don't get precious about settings, I know what I like and it's easy enough to put it back. I'd prefer it was discussed beforehand. It's not difficult in this day and age. It's the easiest way to have a gig run smoothly. If you're on last then it just makes sense. One time, I even helped out the touring band we were supporting. Their rig gave up the ghost and their backup was pretty laughable, so I just let them use mine. Gig goes ahead a lot better than it otherwise would have. Drinks all round. No-one gets to play my basses though, I couldn't care less if it means the band can't play. I would be happy to sell someone a set of strings or a battery if that sorted it out.

As you can see, the power assembly is held in place by plastic tabs. There is some play in mine, but I'm not bothered about it, I'm confident that the assembly will stay in place. If it bugs me then I'll get the glue gun out.

I thought they were so awful that I freecycled mine.

Heh, I actually had someone offer me one of those. Great minds and all that. Nah, I'm going to have a laugh and build something myself. The idea has moved onto using a butchered laptop for both power (3600 or 4000mAh per battery - I have 4 of them) and a housing for a 20W RMS 12V circuit that someone pointed me in the direction of.

If I may pipe up here - the power socket/fuse/switch is one entire unit which happens not to be screwed in but probably held in with (hopefully beefy) clips. I will check tonight. So there will be some movement of the entire unit in its mounting hole, but in normal operation it will be fine (and would not have passed relevant safety checks if it wasn't). Probably a cost saving move. Would it have been better to screw mount it? Maybe, but it's not "loose" in the sense that it's likely to break free from the amp, chase me round the stage and electrocute me and I'm not bothered about it. I'll crack the case open again tonight and take some closeup pics of the area. Then you can make up your own minds about it.

[quote name='Musicman20' timestamp='1337120674' post='1655971'] Crazy low price. How reliable is the HB combo? [/quote] Time will tell. I've done 4 gigs so far with the RedSub amp (3 with just the head (one gig it was also used by two other bands), 1 in the combo) and numerous 2-3 hour rehearsals with the combo. I've used it to amplify my laptop. I've got no fear with the extended warranty and even that doesn't work out then a replacement head is only £150. The cabinet is solid and you'd probably break a toe if you kicked it.

I wouldn't intentionally cause damage to any material possession of mine, and I'd feel even more stupid paying someone to do it for me. Also, I hate clothes that already look worn out when you buy them.

I doubt it. I know a lass locally is about to receive a brand new surf green body for her lefty Strat with holes already dug out of the edges of it.

[quote name='Ou7shined' timestamp='1337071741' post='1654775'] Matt I think you and your RedSub need to get a room, I'm pretty sure Jayne will be getting jealous of your latest bit of fluff. [/quote] Not at all - for my sins I accompanied my good lady to a Zumba class last night, and participated. So I think being a sweaty, uncoordinated mess for an hour paid for the cover Yes, I was the only bloke there and no, it wasn't like the "Call on Me" video, although I did go home afterwards with the best lass in the place, so maybe it was a little like it.

Pics, or it never happened.

I've just received my Roqsolid cover for my RedSub - as you would expect it fits great and of course I took the red seams [url="http://amplifiercoversonline.com/zencart/index.php?main_page=product_info&cPath=107_312&products_id=2700"]http://amplifiercoversonline.com/zencart/index.php?main_page=product_info&cPath=107_312&products_id=2700[/url] It will obviously fit the Harley Benton too, as they're identical.

Chewing the fat with Ou7shined today, I got talking about the project. I tried his Smokey amp (you know, the ones in a cigarette box) in my 1x10, and it was surprisingly loud but farty as hell (as it's designed to distort for guitar). So I was wondering about how to get a convenient rechargeable supply and an idea hit me - power tool batteries. I'm going to play about with a 12V cordless drill I got for free ages ago - batteries might not be any good, but it's a start. If I butcher the handle of the drill then I'll be able to use the battery latch to plug in/out as needed. As for a circuit, I was thinking of kicking things off with the 5W version of this: [url="http://www.quasarelectronics.com/ce0015-mono-audio-power-amplifier-with-preamp-module-range-1.8-5w-rms.htm"]http://www.quasarelectronics.com/ce0015-mono-audio-power-amplifier-with-preamp-module-range-1.8-5w-rms.htm[/url] CE0016 - I know there's no tone shaping on this unit, but I want to keep it simple for now, and there's always the tone controls on the bass... Anyone able to tell me if it will work before I waste twenty quid? Here's all the skinny on the unit - [url="http://fadisel.com/docs/E-16(English-Esp).pdf"]http://fadisel.com/docs/E-16(English-Esp).pdf[/url] I just cracked one of the batteries open and it is a 1300mAh unit. The circuit allegedly takes a maximum of 270mA, so that's a theoretical life of 4.8 hours per battery (and I have 2 batteries).

I screw the saddles down until I get fret buzz/rattle then I raise them until it stops. I've never measured it.

As long as I can hear myself, I'm happy. Don't need anything bigger than a 4x10 for that for the size of venues/stages/gigs I'm doing and am likely to ever be doing.

[quote name='Batfastard' timestamp='1336832197' post='1651694'] You'll need to sort out a regulator/rectifier circuit to stop peaks and troughs in power delivery. Also You may want to put a acouple of vents and fans in the case to deal with cooling. Most importantly though go for a bigger battery spec than you think you need because what ever you build will not be 100% efficient. [/quote] Forgive my high school electronics knowledge, but isn't a rectifier for converting AC to DC? This system will be purely DC. Using an old computer case means that there will be places to mount fans should airflow be an issue. Totally with you on the battery point - will try and get the biggest one I can that fits into the case.

[quote name='mushers' timestamp='1336829415' post='1651653'] your idea does seem sound however with batteries the issue always is once they lose their top end charge which could happen within an hour, will it be pushing enough amps out to keep running the amp after say the first hour ? i have a feeling it should but you wont know till you try it are the whole band going to be using the same amp ? [/quote] Well, I'm hoping that using an automotive power amp will mean that it is happy to work within a fairly wide band of tolerances as it is designed to be powered from a lead acid battery. I only intend this to be a bass amp for me at this time, but I suppose it could be used for keyboard or vocals.

Thanks for the comments so far but I'd prefer some advice on my idea rather than ways of avoiding it. I'm going to build it because it amuses me to do so. It may not even be a good idea, it may not even work. But this is how progress is made. The 40 in WD-40 and all that

[quote name='icastle' timestamp='1336779546' post='1651138'] Why not just buy an inverter and a car battery? [/quote] Full sine wave inverters are expensive, car batteries don't like deep discharging and I'm not subjecting my gear to the abuse that is modified square wave power. I think a neat, self contained unit would be a cool thing to put together.

I might have to play some bass on a beach in July. No power nearby so I'm scheming about building a 12V system, running off a rechargeable lead-acid battery (like ones for mobility scooters or leisure use that can deal with deep discharging). I know very little about stuff like this, but I was thinking of mounting it all in an old computer case for now. I presume that I'll need some kind of 12V preamp (like a Velleman kit preamp or something) before feeding that to an automotive power amp of some kind (full frequency range, not just for driving subs). Would I control the volume at the preamp, or should I have a separate preamp gain and master volume control in between the output from the power amp and the output? I'm going to feed the output into my trusty RedSub 1x10, so it can handle up to 250W at 8 ohms, but there's no reason why it couldn't feed other cabs, as long as the power amp can handle the impedance and the cab can handle the power output, yes? If the amp gubbins take a 5A draw and if I got a 20Ah battery then in theory that would run for 4 hours on a single charge, yes? I presume any tone shaping will need to be done at the preamp stage. Still scheming stuff out, but I think this would be a cool thing to build, as long as I can scrounge together the parts relatively inexpensively. Does this sound feasible, or am I barking up the wrong tree?

Yamaha SB of some sort. 5A or 7A?
