    [quote name='alexclaber' post='259974' date='Aug 11 2008, 02:20 PM']No it wouldn't because the power difference that matters is the amp output (which is simply down to impedance) not the thermal power handling. Remember, speakers don't produce power output, they consume power input.[/quote] Well I suppose the power handling is largely irrelevant given that what I'm looking for is better handling of low frequencies (so a larger xmax, etc.) rather than the overall power dissipation. I was just working under the assumption that an equal sensitivity meant equal efficiency (even at low frequencies) and that this would remain constant with increased power ratings. Not the best idea evidently. Dan.

    Thanks for the input guys. I know the older 2x10s had 16 ohm drivers because one became faulty and I made the mistake of going to Andy's Repairs on Denmark Street to get replacements because I couldn't find exact replacements myself. He then went and bought the only Trace Elliot tens celestion now make, from a US catalogue! Ended up costing me over £60 each, and they were 8 ohms, not 16! I could've just gotten them from Watford valves for half the price. Alex, with the replacement idea I was working on the basis that the frequency response of the replacements does extend down to 40/45Hz (not sure what dynamic range that specifies) and that the TE speakers are more likely to be similar to the orange labels (down to around 70Hz), given the sound of the cabinet - obviously can't be sure about this though, so yeah, too many unanswered questions really. Also the current speakers (and the originals) are only 100W each, so the power difference would be a factor of two, rather than four thirds (which I'm certain would be pointless). Anyway, consider me warned off the change.

    Ok. Given that the amount of treble cut is inversely related to the resistance in series with the capacitor, I've put in three options. In the off position, the resistance is simply that of the permanently wired in resistor (~250k - the figures in the schematic are minimum resistance specs of the resistors I'll be buying and they come in 240k, not 250k). This is the standard full spectrum tone setting of most basses. In the down position (A) the other resistor is added in parallel, giving a resistance just below it's own value. In the up position ( the resistor is shorted, giving effectively zero resistance and the full treble cut. I'm pretty sure that bit's fine, I'm not really certain about how the loading of the pickups affects the tone and output. If I were to follow the Seymour Duncan wiring for P-J blend and master exactly I'd be replacing the p pot with a resistor as it doesn't need to change, but I can't see that this resistor would then actually be doing anything useful, so have left it out. Dan.

    [quote name='bass_ferret' post='259570' date='Aug 10 2008, 10:08 PM']Unfortunately the belief that you need 15's and 18's to get deep bass is a common fallacy. If you get full range cabs you can always turn the treble down and the tweeters off - but if you decide at a later date you need more top you wont be able to dial it in if the cabs cant make it.[/quote] True, decent large cabs based on smaller drivers [i]can[/i] provide deep bass given a sufficient xmax (the Celestion BN10-300X for example apparently goes down to 40Hz as a usable frequency, although sacrificing the highs somewhat), but then for a really bass heavy sound it's not particularly efficient in terms of the weight of all the drivers in the cabinet as the overall volume level will need to come down to accommodate it. Of course the weight issue doesn't sound like it's a problem here, but the other thing is that the sound you get from a 15 or 18 is just different to what you'd get with 10's EQ'd to the same spectrum. Some would say it's just flabbier, while others would say it's a warmer sound (it's definitely worth getting a really good 18" driver to ensure a decent response from it). Of course I've seen reggae artists using just a 4x10 on stage because you just don't need the deep end on stage when it's pervading the entire venue from a huge PA (assuming modest sized stages, this was the Easy Star All Stars playing 'Radiodread' and 'Dub Side of the Moon' at Dingwalls in Camden). For rehearsing and without a PA though, an 18 (or at least a 15) really is what you want for reggae. Klarm, as you might guess from my rig (1x18 + 2x10) I'd say in essence it's a good setup for almost anything needing a fair amount of deep bass, but definitely for reggae plus a bit of classic rock, and I can't imagine SWR letting you down. I'll finish with a quote from Aston “Family Man” Barrett of Bob Marley and the Wailers: "I had two 18” cabinets and two 4x15 cabinets. You need them that big to get that sound, because reggae music is the heartbeat of the people. It’s the universal language what carry that heavy message of roots, culture, and reality. So the bass have to be heavy and the drums have to be steady." Now you're original choice of cabinets seems almost modest!

    Hey fellas, I've attached a schematic I've drawn up for a hot-rodded p-bass. It's a Fender Japan with a Seymour Duncan SPB-2 (hot precision) and I'm getting it routed to add a STK-J2 (hot stack jazz) at the bridge, making it rather like the backup Squire Precision Special I've loaded with the same (only the jazz is single coil). Anyway, I'll get to the point. I never dial down the precision, so that doesn't need an individual control, but I do need a volume control for the jazz and want a master volume for fading in and out where necessary. I almost always have the tone control fully in, occasionally dialling it down either half-way (once in a while) or completely (once in a blue moon). I plan on sticking in a mini-switch for this, and as they only have on-off-on toggles in Maplins (£2, just up the road from me) and I'd rather not order a more expensive three-way on-on-on switch from the internet and have to pay postage, I've implemented a slightly round-about way of controlling the treble leakage. Switch centred (off) is no cut (~250k), down is moderate cut (~23k) and up is proper dub. Aside from this, it's exactly as the recommended Seymour Duncan wiring, [i]except[/i] for the lack of a pot, or even a dedicated resistor for the p pickup since the pickup is already loaded with both the Jazz and master volume pots I figure another would only serve to cut the output further - in fact I'm considering changing the pots to 500k for this reason, but Seymour Duncan don't say anything about using higher values for any of their bass pickups, or for any configuration. Ok, enough from me. Any thoughts? Dan.

    Not having used these specific cabs I can't really comment on the relative merits of each make, but you I don't think you can really go wrong with any of those listed. For reggae and motown the 18's are you're friend, but for classic rock I'd always recommend having some 10's in their for the mid-range. The reason I say this is because the classic rock guitar sound is generally pretty bassy and flabby (c.f. Marshall rigs) and hence are much bigger competition for the bass. You might be able to get what you want from 15's, but you might find the overall rock band sound lacks 'oomph'. I've gotta say you don't see many people using such large rigs - part of the reason being that it seems a bit overkill for any venue where you're able to get good deep bass projection without a PA, and pretty unnecessary for places with a good PA system (awe factor excepted). If you have you're heart set on a 6x10 to go with you're 1x18 rather than a 4x10, then power to you - I just feel sorry for whoever's going to be shifting your gear! Dan.

    Just get a new 8 ohm 200W speaker from here: [url="http://www.lean-business.co.uk/eshop/index.php?main_page=index&cPath=20"]http://www.lean-business.co.uk/eshop/index...ex&cPath=20[/url] Blue Aran may be good but they seem pretty expensive to me, and Watford Valves don't have the BL10-100X listed on their web page at least.

    Hey fellas, As my signature says, I have a Trace Elliot head with two channels that each deliver 300W into 4 ohms. I have a 2x10 at 4 ohms (8 ohm 100W drivers because they don't sell the 16 ohm ones any more) and an 8 ohm 1x18 (soon to be a Trace Elliot one rather than the home-brew). Now I'm not going to go about looking for a 4 ohm 18" speaker to max out that channel as these seem to be extremely rare beasts and of course 18s are expensive, however I was pondering what I could do with the 2x10 to make good use of the power amp both in rehearsals (1x18 + 2x10) and at gigs where I can just take the 2x10. To get to the point, my idea is to buy a couple of higher-powered 10s from [url="http://www.lean-business.co.uk/eshop/index.php?main_page=index&cPath=20"]here[/url] and separate the input and link jacks, one for each driver. This means I would be able to have 400W from my 2x10 running both channels into 8 ohms - perfect for being able to hear myself on stage (the lows will be flooding the entire venue from the FOH anyway, but I'd still like to have as beefy a sound from the cab as possible). Then when I'm back rehearsing and need the 1x18 to get the full range sound I can use a 1/4" jack splitter (I realise I'd probably need to make one using proper speaker cable rather than using a standard Maplins one) to put the 10s in parallel and run that channel at 4 ohms (then only putting 300W into it, but that's fine). Now I have three questions: 1) Does anyone expect that all that power (400W) going into a 2x10 designed for 200W would cause a problem? 2) Would the green label celestions be a bad idea due to the weightier bass? I've emailed Celestion asking what the frequency response of the Trace Elliot custom speakers is so I can compare to the green and orange label celestions. 3) Is it just a bit stupid to think that 400W coming from two 10" speakers is going to give a much louder sound than 200W coming from the same configuration, albeit the replacement speakers being capable of handling more bass in particular? I don't know the SPL of the TE speakers, but the replacements would be 96dB (green) or 98dB (orange) (see spec [url="http://professional.celestion.com/bass/"]here[/url]). That is all. Dan.

    I don't think that'd be a simple mod as if I remember correctly the front switch is latching on the GP7, and even if it weren't, the physical logistics of getting a jack socket added and connected are pretty nasty. This is one of those things that reminds you that the GP12 series didn't just add five bands of EQ.

    Oh go on then... PM'd.
  11. danlea
    I'm really on the fence with this one. I'm just considering whether or it's worth my while to ditch my larger homemade 1x18 for this to make my rig entirely TE. I wouldn't be able to pick it up for another couple of weeks anyway, so I'll keep shtum for now (as far as posting my reasoning can be considered keeping shtum).

    Getting rid of stuff that's been collecting dust... Firstly, I live in Camden close to Euston and King's Cross, so it's very easy for someone in London (or someone travelling into London) to pick something up, but I will post any of these items for a fair price. Decent photos of all items are attached. [list] [*]Let's start off with the elusive [b]Trace Elliot SM7EQ[/b] (7-band graphic equaliser) pedal [b]in very good condition[/b], [b]with adaptors[/b] so you can plug it into your 9V power adaptor/daisy chain! If you don't know about this, all the Trace Elliot pedals operate at 18V for the extra headroom, and I'm guessing most of you know that it's a royal pain in the gluteus maximus to run it with a separate power supply (if you can kind one that doesn't weigh as much as four pedals) or to run it with two 9V batteries. My solution was to get a [url="http://www.diago.co.uk/component/page,shop.product_details/flypage,shop.flypage/product_id,39/category_id,3/manufacturer_id,0/option,com_virtuemart/Itemid,206/"]Diago voltage doubler[/url] and a [url="http://www.uk-automation.co.uk/21mm-25mm-adaptor-p-1267.html"]2.1mm - 2.5mm DC plug adaptor[/url] from Maplins. You can find a manual for this pedal [url="http://www.21frets.com/catalogs/Sm7eq.pdf"]here[/url] if you want specifications or the like. Original box and manual are long gone. One last note, the input level light changes colour, so it's like having the three LEDs from a SMX GP7 in one light. [b]£65[/b] + £4 p&p. [*][b]!SOLD![/b] Next, a classic [b]analogue bass stereo chorus pedal[/b], the [b]DOD FX62[/b], in [b]excellent condition[/b], boxed with manual and a DOD "America's Pedal" sticker. I'll also include the DC to battery adaptor shown in the picture so again, you can just plug it straight into a standard power supply. [b]£28[/b] + £3.50 p&p. [*]The last of the pedals is a [b]Digitech Bass Squeeze[/b] dual band compressor in [b]excellent condition[/b], boxed with manual and registration card. [b]£35[/b] + £4 p&p. [*]Last of all, a chrome [b]GrooveTubes fat)finger[/b] for bass. It has plenty of good [url="http://www.stringsdirect.co.uk/products/406-fat_finger_sustain_tool_chrome"]reviews[/url], but it didn't make one jot of difference for me on a Precision with heavy gauge strings (I was hoping it would help shift a couple of dead spots). I suppose it makes it wouldn't, given that the headstock is hardly low mass as it is! Anyway, I tried it out, took it off and that's it. [b]£14[/b] + £2.50 p&p. [/list]

    Excellent condition (aside from a small blemish on the front near to the preamp and a couple of tiny dings on the headstock) and sounds superb - it has a really great woody tone rather than the harsh, bright sound on many acoustic basses. It stand up very well to on stage volumes without feeding back. It's 32" (medium) scale so very easy to play. It also means it's very compact for an acoustic bass. The preamp has a volume knob, bass/mid/treble/scoop sliders and mute/phase buttons. I live near Mornington Crescent, Euston and King's Cross, so it's pretty easy for most Londoners to pick this up, and anyone else coming into London for that matter.

    The unit is currently in our rehearsal studios in Hackney, London. Excellent condition. The screws have acquired some of the rust you see on all TE stuff of this age and the compressor balance knob is missing it's red cap, but as you can see it's certainly not an eye-sore. It's the original black 'pimple' covering with the original Trace Elliot Celestion speaker. I've attached the manual for the range, but here's a quick summary: It's 300W RMS at 4 Ohms (i.e. with an 8 Ohm extnesion cabinet), obviously it has the fantastic GP12 SMX preamp (valve/SS input blend, 12-band EQ, dual band compressor with individual controls, effects blend level), a footwitch input (footswitch not included as per usual, but any stereo jack momentary footswitch will do - you can get one made cheaply here: [url="http://www.redonionsolutions.co.uk/General/DualMom.htm"]http://www.redonionsolutions.co.uk/General/DualMom.htm[/url] - they also sell on ebay) and a full-range/high-pass effects loop with send level. I'm selling this because I've purchased a 600W head from the same range (I just love the sound you get from these - don't be fooled into thinking you always just get that Trace Elliot signature tone from it). It's very compact and a great gigger - has great lows and responds all they way up into the high mids (you can get a great twang out of it, unlike a lot of 15s) but is even better when teamed up with a 2x10 extension to give you a stronger mid-range. Anyway, most of you know this sh*t already. The amp resides at the Premises studios in Hackney (E2 8JL). [b][s]£325[/s] £250[/b].

    Thanks! Just for the record, the bass was delivered promptly in excellent packaging and a hard case, and aside from the mild scuffing on the pickguard (which you can only see in reflections) it really was in pristine condition - couldn't find any marks anywhere! I showed it to our guitarist and he said he couldn't believe it was second hand. This bass itself is something special. My proudest purchase in a while!
