Obvious advice - groundwound, half wound or flats will reduce fingerboard wear. Depending on what you paid , scarcity of FNA Jazzman fretless, what you think about FNA you have and the luthiers available to you, a new ebony fingerboard might be a better financial possibility than sell / trade and find another.

Stonking colour, great fun

Hopefully it is the send - return jack sockets suggested previously Is it a 50hz mains hum (if you do not know this hum, measure the hum frequency with a tuning meter or phone app). If it is 50hz it is could be a smoothing (filter) capacitor in the power supply circuit. These are usually easy to replace (and very cheap) if you are ok with the soldering iron. Peavey are good with support with circuit schematics - even for kit back into the 80s. Some very good images of the internals here [url="http://www.ajaudio.co.uk/PEAVY%20TOUR%20700%20%20AMPLIFIER%20REPAIR.htm"]http://www.ajaudio.c...ER%20REPAIR.htm[/url] Capacitors easily accessible and the pcb tracks and pads are substantial making diy repair easier.

4x15 or 4x12 with 'cross firing' drivers ? Something the size of 2 dubsters would head into behemoth territory.

They are a bit unfashionable at the moment for no apparent reason whatsoever...thus the second hand price makes them a steal. [/quote] Understatement alert The German Corvette that went for £375 on here was just incredible. Makes quite a few basses look seriously overpriced. Makes the buy once, buy right, buy for life much more straightforward.

Spooky - I found Natalie Prass on youtube yesterday through chance (did not see Jools). Just how many excellent musicians are out there that are relatively unknown? I was impressed.

Corvette gets my vote at the moment. Just seems able to do most things - have had mine doing the Gibson EB3 thing through to (and this surprised me) upright bass type sounds. Great thing about corvettes is the J size pickups - alternatives e.g. EMG, DiMarzio are straightforward.

[quote name='gjones' timestamp='1429553938' post='2752566'] Raise the pickups nearer the strings. That usually gives a bass a bit of ooooomff! [/quote] Good advice. If that fails, in no particular order[list] [*]Change string type [*]Humbucking J type pickups e.g. DiMarzio DP123 [*]ten band graphic eq might be possible solutions. [/list]

Highly rated in the 80s at the time.

[quote name='bootsy666' timestamp='1429469807' post='2751693'] Besides technical stuff, I've brought some good quality black leatherette, I used the same stuff to wrap my vba400 in and it came out quite nice. I did plan on using it on the front baffles only before the speakers go in, but I'm having second thoughts now. I guess I could always remove it if it doesn't look right. [/quote] Tuffcab is your friend (or even black paint on the baffle).

[quote name='JTUK' timestamp='1429374085' post='2750942'] The 360 is a 40 plus year old cab and even back then I don't recall them being usable without a 412 linked up..? Certainly the one I had in the late 80's needed something like that. [/quote] Seemed OK to me at the time, then again I was 18/19 and what seemed ok to me in the very late 70s would not now. Have just done some Google and found / remembered the cab was a 361. Quite popular at the time [url="http://www.bassplayer.com/amps/1166/full-circle-360-degrees-of-the-acoustic-360/26984"]http://www.bassplaye...ustic-360/26984[/url] it seems. I saw Ricky Cool circa 1977 - bass player was using one and I just thought - yep got to have one.

[quote name='bootsy666' timestamp='1429350869' post='2750638'] .....I did do my homework before starting, and decided against the modern designs that computer programs claim are the best, instead I went with the same idea as the early sunn cabs that have been very successful. [/quote] [quote name='bootsy666' timestamp='1429367323' post='2750848'] I've made 8 ports of 2 inches each, one for each speaker, if this ends up being too much then I will block some off? [/quote] I suspect some classic cabinets would probably be sub-optimal when subjected to computer aided design - I am particularly thinking of the Acoustic 360 that I once owned. Blocking off is a good pragmatic solution. If you find you need larger ports they can always be put in the back of the cabinet.

[quote name='throwoff' timestamp='1429286357' post='2750083'] Nothing in the instrument makes a single bit of difference to the tone other than pickups and electronics. [/quote] You need Unobtanium. It is the only material to have the frets, bridge, machine heads and nut made from. From the first moment my bass had Unobtanium components fitted random strangers have said to me - what a tone, how much more sustain, how quick the notes decay, what attack and growl, what smoothness and bloom. Choose description for target market In serious mode, I both mostly agree with this and slightly disagree. The only bass I have where I think (note lack of objective quantifiable measurable evidence) there is a significant effect other than pickups, electronics and strings is my aluminium neck Kramer. Given it has DiMarzio pickup and maple body as do some of my other basses, it has a greater hifi / clarity to the tone than my equivalent basses. It also has another effect which I can only best describe as 'playing itself', the strings respond very dynamically to playing, it has a great tactile feel. No other solid body bass I own does this (despite having the same strings / same scale length). I can reduce most of my basses sounding to sounding the same.

[quote name='MiltyG565' timestamp='1429206843' post='2749290'] Ha! Like on lawnmowers, with the rabbit at one end and the tortoise at the other! [/quote] Thanks for that you just reminded me of the big green thing outside that keeps growing and now needs time with machine that has the rabbit at one end and the tortoise at the other! I did it a few days ago and the b* thing has grown faster than ever with sunshine.

[quote name='HazBeen' timestamp='1429207816' post='2749312'] [url="http://www.audioheritage.org/images/jbl/photos/pro-speakers/grateful.jpg"]http://www.audioheri...rs/grateful.jpg[/url] 24x12, pitiful... [/quote] So the 24 x 15 cross firing in blocks of 12 vertically? Eminence 3015LFs with (as a first estimate) 12 x 6" mid range speakers. Would have to be active crossovers to keep weight down. Approx 9.6 KW power amp would be starting estimate. Cabinet and port dimensions to follow (if I am bored at work tomorrow).

[quote name='MiltyG565' timestamp='1429205011' post='2749256'] Reducing sustain is much easier than increasing it. There are times when I've been crying out for sustain on slower songs. [/quote] Time for the 'sustainer changer' bridge, lever adjustable either way

[quote name='discreet' timestamp='1429202075' post='2749206'] Plus, sustain is a highly overrated characteristic anyway. Does anyone really need a lot of it for bass playing? [/quote] Many is the time when I would have liked a sustain reducing bridge, I have even tried rubber shim in neck pocket to achieve this effect - did not make much difference. Was back to the good old sponge under the strings method.

Other options (but much more expensive) Eminence 3015 or 3015 LF . Used in earlier generations of Barefaced cabs and in the Fearful range. They also appear in BFM cabinet designs.

[quote name='acidbass' timestamp='1429050812' post='2747573'] Unfortunately he is only under obligation to answer police questions if under arrest. He can feasibly not turn up to interview, or give a 'no comment' interview, unless there is enough evidence initially and he is charged with theft. [/quote] Good points, I was hoping for the most positive outcome. Given the'front' of what has taken place the 'no comment' interview could have been a high probability.

With One VBA 400 and Barefaced Dubster (2 x 15) I could (can) make the concrete slab and walls of the hall (900 + capacity) I rehearse in vibrate. A most odd sensation feeling the concrete foundation raft move - the earth did move for me Not sure what that says about 1950's construction. What the 8x15 and 2 VBAs used in full tilt will do will be interesting to say the least. I await the BBC news later this year! [url="http://www.linearteam.dk/?pageid=winisd"]http://www.lineartea.../?pageid=winisd[/url] - input the Thiele-Small parameters (from Celstion website) and cab dimensions.. Application will tell you what port sizes, airflows, frequency response the cabinet will theoretically give.

So disappointed for you that plod could not follow through. Having kit nicked is a most unpleasant feeling (have experienced theft - but not in such a personal direct situation with intent). Seems even worse since it is another (alleged) musician - having said that I have been ripped off with failed purchase on here a long time ago so have some sense of that as well. Remember the majority of us are good. The perpetrator will get his due justice in the course of time, he will come unstuck. If he is lucky it will be lawful, if he is unlucky will be worse. No offence, is there anything that is desperately needed - many here will help out, me included.

Deffo have different musculature on left hand to right. Cause - who knows. LH grip is significantly stronger than RH, but after 42+ yrs bass playing is to be expected I think.

[quote name='Beer of the Bass' timestamp='1429030342' post='2747218'] Have you used a modelling program like WinISD to figure out the size and shape of the ports in the front? That should be your first port of call when trying to work the area and length of ports to use - they're not just vents to reduce heat. I wonder how much heat the drivers will actually produce - If that's a VBA400 in the picture, each driver would only be handling 50 watts at full output, so perhaps heat won't be such a big issue. [/quote] Good advice and sharp observation on the VBA 400 and the power sharing. A rough estimate based on my Dubster suggests an 8x15 would need 1670 cm^2 of port area. This is a very rough estimate, WinISD or similar as suggested is the way forward if you want a correctly vented cabinet.

[quote name='Billy Apple' timestamp='1428961407' post='2746544'] I'd be interested to know how much more air this will shift as opposed to an 810? I thought the magic was all in the voice coil and xmax excursion, which could be just as big for a 10" with the extra inches in a 15 being the paper cone? [/quote] A well made point about speaker volume displacement and excursion. We now need the technical input of Mr Claber and Mr Fitzmaurice - what would the optimal 8 x 15 look like? Single column of 15s or cross fired blocks of 4. How could it perform?
