I'm having some issues with an EQ I have designed. I have attached two files, the frequency response graphs and the schematic. It won't take long to see the issue on the 100Hz and other filters. Anyone got any ideas? Frequency response graphs can be found [url="http://inverseaudio.co.uk/Results.pdf"]here[/url] A cracking discussion here! made it to page 12, time for bed now though!

[quote name='LukeFRC' timestamp='1333319949' post='1600131'] wooah that 100hz filter is crazy! [/quote] Yeah, there is slight concern! I could PM you a copy of the schem if you think you could offer insight.

Aye! Well it's a hobby that I want to take to the next level, so there is no harm in being ambitious! There won't be a huge amount of progression over the next couple of months while I finish uni. Then the real work begins!

Ok test results haven't uploaded right. Try [url="http://inverseaudio.co.uk/Results.pdf"]THIS[/url] instead.

It's coming along nicely. It's on holiday atm at university getting marked. Fitted it into a quality street tin (pic attached) The filters have some issues. Below the centre frequencies on the band bass filters, when summed, they cut if boosted and boost if cutted ... If that makes sense. I've attached a pdf which should hopefully make more sense of that. If anyone came up with a reason/solution for this, I'd be eternally grateful. The two mid frequencies were designed to cut out some resonant frequencies from my bass, the bass and treble were designed to be boosted. [attachment=103881:photo.JPG]

incase anyone is interested I discussed this on my blog last night: [url="http://allthatjazzbass.blogspot.co.uk/"]http://allthatjazzbass.blogspot.co.uk/[/url]

It was the old, everyone thought someone else had done it trick. Now or never. Decent cash waiting if the right band is available at short notice! Dave

Completely understandable. Anyone?

I'm sorry if this is in the wrong forum but this is a act of desperation. Due to unforeseen circumstances, I'm without a Paddies Day band for a big event at Huddersfield's Students' Union. It's usually rammed all night. If you are a Irish Folk or Popular Covers band and can make it into Huddersfield, please get in touch, there is a gig waiting for you .... tonight!! My name is Dave, you can reach me at 07817648149. Paid by cash and Guinness. Dave.

I'm in Huddersfield, West Yorkshire atm but tend to get around a lot. Working out resonantly well, got a bit of supply ripple in the signal line and the FR of the bass control is a bit (ok, quite a bit) off. Deadline is fast approaching so trying to keep my head down! Long Term Idea's: Distortion circuit in series with a variable band bass circuit. (Then wired in parallel with filter circuits). Then have a separate distortion output for studio work. Revise EQ's, make more efficient. Separate Line In for reamping Compressor (wouldn't know where to start tbh!)

I've had a few conversations with various bass chat members about my preamp design. I'm doing it as a dissertation for the my degree. I got it up and running today, hurrah! Still in its simplest form but I can't tell you how relieved I am. So much so, I've decided to share it with the world. Check it out on YouTube [url="http://youtu.be/QXhuo2SRonM?hd=1"]HERE!![/url] I would have loved to document the work more but it would have been far too difficult for me to keep up with the workload. Deadline is next Friday but I'm not looking to do anything major to it before then. Anyone got anymore long term ideas for it?

Interesting! I had this problem with a stretch of 3m cheap unbalanced cable. The shielding and core was so small and cable was so long that the capacitance of the cable was much lower than average. Blah, blah, blah, a low pass was formed knocking a load of top end off the signal. I wouldn't expect this with van damme but maybe the kicking and wear and tear of the cable has broken or thinned out some of the shielding and or core?

Just bought some Fender Tuners off Nick. Great to deal with, fast and safe shipping. Be 100% confident dealing with this gentleman.

Seymour Duncan [color=#282828][font=helvetica, arial, sans-serif]SBP1 Gets my vote. Got one in mt CV P. The best complement I can give it is, it's ability to sound like a P Bass![/font][/color]

I once snapped a 421 clip and resorted to using an elastic band around the stand. I don't know of a alternative clip.

Just a quick bump. Project has came a long way in a short amount of time, its a great learning curve. Just spent all weekend sanding, take a look! .... [url="http://allthatjazzbass.blogspot.com/"]http://allthatjazzbass.blogspot.com/[/url]

Fair enough. There is a tiny but noticeable difference.

Interesting idea. Forgive my ignorance but what are the benefits of having no load tone pot? As far as I am aware a tone pot set to "full" passes everything up and over 20kHz. Removing the load wouldn't make a difference to the output signal as the impedances preamp inputs are usually set between 1 and 10M. Am I missing something?

Just bought a P Bass Neck form Paul. Great communication and price. Nothing less than perfect. Cheers Paul.

Was so close to buying paint for this but chickened out last minute. Vintage white has a hairline lead!

Vintage White has taken an over night lead! Only 31734 days left to vote. Fiesta Red always reminds me of the BBC News page. I'm sure someone will tell me they are completely different colours!

Got to love the P/J on a J Body. Looking forward to seeing the final results.

I have the Squier CV in "Fiesta Red". Regardless of what colour it actually is, it's beautiful. I think deep down I secretly know what I'm going to go for, but lets see how the vote goes over coming days/weeks.

Thank you! Yeah, obviously I'm not voting but shame to see no votes for the fiesta red yet!

Not that it affects me in anyway. I've narrowed the refinish colour down to 1 of 3. 1. Olympic White [attachment=99801:0190662705_frt_wlg_001.jpg] 2. Fiesta Red [attachment=99799:red1.jpeg] 3. Vintage White [attachment=99800:offwhite.jpeg] [url="http://allthatjazzbass.blogspot.com/"]VOTE HERE[/url] and help me decide!
