Davebassics Posted February 29, 2012 Share Posted February 29, 2012 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? Quote Link to comment Share on other sites More sharing options...
ahpook Posted March 1, 2012 Share Posted March 1, 2012 (edited) mate - that is a lovely bit of work. very tidy construction and a niiiiice sound. long term ideas ? could you get it all onto one board and put in a 1U case ? team it up with a power amp and you'd be away.

sprocket123 Posted March 1, 2012 Share Posted March 1, 2012 Hey davebassics ; where are you based , might interest some in BC Quote Link to comment Share on other sites More sharing options...
Davebassics Posted March 4, 2012 Author Share Posted March 4, 2012 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!) Quote Link to comment Share on other sites More sharing options...

LukeFRC Posted April 1, 2012 Share Posted April 1, 2012 the bass freq point is interestingly the same as the warwick 2 band preamp. they have the high at 2k not 1k but similar and not very common 'tight' grouping of eq points. Quote Link to comment Share on other sites More sharing options...
sprocket123 Posted April 1, 2012 Share Posted April 1, 2012 Yep , it should have an additional low & high mid i guess Quote Link to comment Share on other sites More sharing options...
Davebassics Posted April 1, 2012 Author Share Posted April 1, 2012 (edited) 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.

Davebassics Posted April 1, 2012 Author Share Posted April 1, 2012 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! Quote Link to comment Share on other sites More sharing options...

Davebassics Posted April 12, 2012 Author Share Posted April 12, 2012 I agree. In no way shape or form does my current design have any commercial potential so I'm really effected (give me 10 years). I would imagine that there are large numbers of students who come out of uni with a product they could take into a market, I feel sorry for them.

[/quote] I came out with an idea and a product to pitch but not all the skills needed. It's going to take a few more years programming experience and research/number crunching and then I'll have to find the right company to pitch too Quote Link to comment Share on other sites More sharing options...
