I was given a '70s Fender body that had a tiny bit of checking on the finish:



This was a refinish though - but it had apparently been done by a decent luthier.

Good luck with the sale, guv!

Oooo ta Alex, I'll give that a bash with a slot port, methinks.

Cheers Alex. So the 3" round port will be OK then - bit long for the prospective size of the cab though - I'll have to play in WinISD.

If I were to build a slot port, and guidance on dimensions? Don't go spending loads of time on it though...

OK, I picked up an [url="http://www.eminence.com/guitar_speaker_detail.asp?model=ACOUSTINATORNH2008&speaker_size=8&SUB_CAT_ID=6"]Eminence Acoustinator NH2008[/url] with the intention of using it to make a decent small cab as a practice amp - but with the hope that I may be able to use it for acoustic style gigs etc.

[url="http://www.eminence.com/pdf/acoustinator-nh2008.pdf"]Spec sheet[/url]

Looking at the [url="http://www.eminence.com/pdf/cab-acoustinator-nh2008.pdf"]cab design sheet[/url] it appears that I can get something that is fairly flat (at -3db) down to 60Hz or so, using a 0.8 cu ft box, but it will reach displacement limit at 55W. Smaller cabs will roll off sooner but have a higher wattage displacement limit.

Originally I'd intended to simply ccale down the design for the Electrovoice 1x12" cab, but thought I ought to look into it a bit more.

The vent recommendation is for a single 3" round jobbie 9.23" in length, but I was wondering how using a larger "slot" style vent as per the Electrovoice, fEarful and Barefaced cabs would affect things. From what I understand, a larger vent than is "correct" can offer some benefits, or am I going completely bonkers?

Bracing is your friend.

Hey shockwave, I wasn't trying to do your sale down - I was trying to suggest you could try selling on eBay and get a decent price for it, since thre's no interest on BC.

Look, there's [url="http://cgi.ebay.co.uk/Roland-DB-900-D-Bass-Amplifier-Bass-Amp-Combo_W0QQcmdZViewItemQQ_trkparmsZ72Q3a1683Q7c66Q3a2Q7c65Q3a12Q7c39Q3a1Q7c240Q3a1318QQ_trksidZp3286Q2ec0Q2em14QQhashZitem160325676546QQitemZ160325676546QQptZUKQ5fMusicalInstrQ5fAmplifiersQ5fRLQQsalenotsupported"]one on eBay at the moment[/url], 3 days to go, bids up to £280 already - and that's a local pickup auction too.

The fretted comes with some fairly coarse roundwounds that came straight off, and initially I put TI Jazz Flats on. Thought I'd try the Gallis, and they feel nice, are higher tension than the TI flats, and have a fatter bottom end, I would say.

Gallis are quite fat strings though - I worried that I'd need to cut the nut but it was OK in the end.

Now sporting a set of black Galli Tapewounds



Looking at your avatar, I reckon they'd look very nice with black tuners rather than the shiny chrome 'uns.

[quote name='walbassist' post='451897' date='Apr 1 2009, 08:09 PM']Nope, it's standard on the new 2009 model, along with a spruce (not cedar) top.[/quote]

Interesting - thumb rest pics not even on the Godin site yet, though they mention the spruce top (think spruce may have come in with the SA stuff, as mine looks to be spruce too).

Makes sense to have a thumb rest, though. May look into having one fitted on mine. Wonder if Godin would supply one....

Here's mine:

Interesting with the thumb rest. IIRC the original version of this (was it called the Acousticbass then) had this, but it was dropped for the A4/5 models. I assume this is an aftermarket fitment?

I have a fretted A4, and have just taken delivery of the last one of theose clearour GR20s - still waiting for a cable though, as they didn't have stock of them

MDF - it would be VERY HEAVY!!!!!!! Make sure you wear a mask when sanding/planing/routing MDF.

If you went with 12mm ply, then I would keep the external dims the same and add some bracing. I would also use birch ply for the extra stiffness and void-free-ness it offers.
These cabs aren't THAT sensitive to volume, IMO. As far as what bracing to add, then I'd think a couple of ply "ribs" down the back and side panels would do the job - say 40mm strips glued edge on to offer greater stiffening. Then maybe a couple of diagonals from these ribs up to the top and bottom of the cab. The foaming Polyurethane glue is your friend here (unless you get it on your skin).

Extending the top of the port - you will be marginally lengthening the port, so it may have an effect.

Insulation - I don't know this stuff, but I'm assuming it's not going to flake into little bits like the usual Rockwool stuff would? It sounds a bit thick - a lot of staples may hold it back - or could you half its thickness by peeling it apart?

[quote]Originally Ofcom promised to safeguard spectrum in the 800Mhz band for wireless microphones and digital terrestrial TV services, but it appears to have had a change of heart.

Now it proposes to make the whole 800MHz band available for mobile broadband and related services and find "alternative spectrum" for wireless microphones and digital terrestrial TV.[/quote]

Most people seem to reckon the stuff from CPC is better quaility than the Maplin stuff.

OK chaps, this is taking up space, so make me an offer - I'll take £30 + postage, or £35 shipped (and that's a bargain, as you won't get shipping for £5 for this baby).

Quick bump for this. I'll take £40 inc UK delivery.

Don't really sell much stuff here, but have been around since the early days of Bassworld, if that's any comfort...

If it helps, it looks like you could get it shipped (if billyNB were willing to box it up, of course) for [url="http://www.parcel2go.co.uk"]£8.99 + VAT[/url].

Stuart, have replied to you email.

New thread started.

Left over from the splitting of my cab (sniff).

[url="http://www.bluearan.co.uk/index.php?id=EMIGAM15A&product=Eminence_Gamma_15&browsemode=category"]Here's the cheapest place for them new[/url] - they come in at £62 delivered.

[url="http://www.eminence.com/pdf/cab-gamma-15a-2.pdf"]Here's the spec sheet from Eminence[/url]

[url="http://www.eminence.com/proaudio_speaker_detail.asp?web_detail_link=GAMMA15A-2&speaker_size=15&SUB_CAT_ID=2"]Eminence website page[/url] - this may be a slightly different speaker, as it is named the 15A-2, but the specs appear to be identical.
As you can see from the links, it is an 8Ohm 300W driver, suitable for going into a ported box between 40-136 litres (1.4-4.8 cu.ft.) - the box I had it in was bang in the middle of that range at 3.2 cu.ft, and it sounded stonking.

It has had light use - mainly home/rehearsal, as when I used the box it was in at a gig, it swamped the rest of the band for the rooms we play in - so I decided to sell the cab ratherthan it take up room. I am confident it is in perfect working order - it moves freely when the cone is pushed in with no scraping or catching. The oly thing is that the fibre gasket tore away when it was removed from the current enclosure, but I have some weather sealant strip to put round it to replace the gasket.

I've had some interest already, but thought I may as well post a "proper" thread as well.

I'd be looking for around £40 + delivery (or collection from near Hertford, East Herts (SG11)).

OK, the bare cabinet is now sold, so there is an Eminecne Gamma 15" available for anyone who's interested.

Quick bumpage, and a note that I still have interest from someone in the bare cab, so either speak now or hold your peace - also if anyone's interested in an Eminecne Gamma 15, let me know!

I'm in East Herts - near Hertford.

Swap it for the ASAT? (joke)

Without wishing to cast aspersions on that particular seller on Amazon, I'd be wary of Amazon marketplace sellers too - I bought a Shure 58 Beta from one, and it was a fake - weight was nowhere near that specified. They were very good about the return, though.
