[quote name='Billy Apple' timestamp='1464288955' post='3058255'] Tfhhft! How many permutations can there be of a P Bass with flats? [/quote] Given how many have been made (and we all know they are different, never mind copies, tributes etc) x the range of flats available I suspect the answer is somewhat large No immediate answer on Google about how many Fender P basses have been made in total.

Bill Fitzmaurice will be along soon to explain why these top loading bins do not perform as well as horn loaded bins.

have been using Peavey with DDT for years. No ill effects yet some may disagree

Is it possible to get it rewound, plenty of pickup builders about. I suspect this will be far more cost effective than Novak or MEC replacement.

Penetrating oil, soak for a long while. Only problem is the penetrating oil will cost more than scrounging a s/h bridge saddle

[quote name='Twincam' timestamp='1463574015' post='3052433'] It ok I'm not stressed or wound up, slightly irritated maybe. A toothbrush? Is it an old bone one? Ivory? Please don't tell me it's plastic. [/quote] At £12,000 it should be made from unobtanium at the very least

Done being able to read helps

Midweight head, lightweight cab. Sometimes glass and bog iron head (got to love those Partridge transformers). Unable to vote

Enjoy the benefits of kit that can be repaired locally and cheaply. I like (older) Peavey kit for this reason, bombproof and IMO good tone.

Could be worth looking at the grounding layout. Merlin's book is a useful guide, online chapter here http://www.valvewizard.co.uk/Grounding.html. Some grounding techniques are subtle (certainly would not have been obvious to me) e.g. only connecting one end of shielded cables.

Following on from Beedster's expansion I would like to add some other elements of complexity that I believe should be considered. In playing from notation the difficulty may be in 'reading' rather than physical technique (stated above by the time I had typed this ). If deciphering a tune by ear the difficulty may lie in recognising / working out what is being played rather than the technique difficulty. These both represent cognition and comprehension difficulties. Perhaps some questions should be located in finding out what bass players perceive it is that makes some music difficult to play and other music straight forward. This qualitative insight might help shape the next phase of your research. Completely random thought, ask bass players to list 10 tunes (bass parts) in order of difficulty giving them free choice. With a sufficiently large and varied sample, subject the notation to AI and see if the machine learns what constitutes difficulty (if this is technically and computationally possible - I recall something similar has been done about hit songs over time?). Once this is possible, reverse the experiment. Machine rank some common music for difficulty, ask bass players to do the same. test the statistical significance, feed the data back into the AI. PhD for anyone?

Done. Suggestion - it would be worthwhile having a free text box to seek comments about the questions and possible further questions (seeing Jazzneck's post, did I miss a comment box?) As an example. I found the qn about ability to play in differing keys difficult to answer. I can relate to it when I played Sax and was not fluent (or anyway competent). As a bass player I do not perceive keys as any great complexity (all the notes are there to find - or not). Are you working on positivistic methods e.g. an algorithm, qualitative or the 'mixed-methods' paradigm?

It will be worth it when sorted There is something very satisfying having kit that can be self repaired, something that will increasingly be less possible.

My next port of call would be adding a centre tap / humdinger to the heater circuit (assuming it does not have one). Straightforward to implement. [url="http://www.valvewizard.co.uk/heater.html"]http://www.valvewizard.co.uk/heater.html[/url]

Should be a cheapish fix, capacitors are not expensive. Well within the scope of DIY repair since the PCB tracks in the older Peavey kit are substantial.

Worryingly I recently played a Farida tele (standard pickups) through a Stagg practice amp. At low / medium volume it was seriously good, on a par with my USA tele and valve amp. There are many good pickups out there, even cheapie OE. I have had good results with Kent Armstrongs and DiMarzio.

[quote name='Dad3353' timestamp='1462832020' post='3046182'] All is not spectral analysis, though, as illustrated by a Youtube (I can't find it right now...) which showed, for the same sample heard, two faces mouthing a different syllable. Depending on which face one watched, the interpretation of the brain changed to reflect that seen. Hearing is a very psychological experience. Not saying, of course, that the maths don't matter, just that there's more still when we listen to stuff. Edit: Found it ..! [media]http://youtu.be/G-lN8vWm3m0[/media] [/quote] The measurements and maths are a starting point. It may not be possible to produce a plausible effect however the journey is intellectually interesting to me. The mk1 human ear will be deployed in field testing

As always, some parts seem quite straightforward, others much more subtle and involved. I am surprised how similar the frequency spectrum (harmonic content) of basses are. My Warwick Corvettes, fretless and fretted (with same strings) are remarkably similar and not that different to Gibson SG. Re-learning university mathematical Physics is an interesting experience 36 years later, so much I have forgotten .

[quote name='McBass' timestamp='1462533758' post='3043816'] Long shot, but does anyone know of a DAW plug in that'll make and electric bass sound remotely like an upright? My hands won't handle an upright due to tendonitis. [/quote] At the moment I am exploring some solutions to this end, possibly leading to the 'Uprighter' pedal. To date I have sampled my various basses (fretted and fretless) and double bass. Fourier spectrum and envelope analysis points the way forward. I have also identified some problems that require further thought.

[quote name='Tim Chapple' timestamp='1462809553' post='3045831'] Still more fun than a "which bass is best for metal?" post though right? [/quote] Someone will have to step up to the plate. Cometh the hour, cometh the question: "Which castors are best for metal?"

You could try emailing Peavey support in USA. I have found them to be excellent, to give an example I enquired about the heater current available from a 1980s valve amplifier transformer. Answer (and other useful information) came back very quickly. You could also try the Peavey forums. If you were closer I would offer to take a look and see what might be awry.

You will need a mesh cage over those exposed ports Porting upwards into the space where the head was could be a 'cool' solution. Is there sufficient space and length?

[quote name='jimbartlett' timestamp='1462254913' post='3041422'] I had a look after you posted this and they do stick out slightly but I've never noticed a problem. I must have hard skin on my hand due to the original bridge �� [/quote] My delicate palm and soft hands I suspect it was one of those thing that once noticed becomes irritating. The solution for Hipshot is quite simple and applies to all their saddles of this type.
