Stas Posted August 23 Share Posted August 23 Hello dear friends! It's been a long time since I've written anything about my achievements in building preamp. Finally, we managed to sit down more thoroughly, and make a small recording, and for greater interest we will do it in the form of a blind test. There are 4 different basses recorded here, among which there is washburn with my copy of wal. All bass guitars are stacked in a mix of software with one volume level, and with on-board adjustments. No external equalization was performed. Can you guess which one is which?)

Andyjr1515 Posted August 23 Share Posted August 23 My guess is that the 3rd one is the Wal circuit 1 Quote Link to comment Share on other sites More sharing options...

Stas Posted September 2 Share Posted September 2 Hello everyone, friends! Today I finished the first set of pickups in multicoil format. I changed the form factor a bit, but kept all the original coil arrangements. I will make the first samples soon, it remains only to install them in the bass. 7 Quote Link to comment Share on other sites More sharing options...
funkle Posted September 2 Author Share Posted September 2 Ooh, another set of pickups for folks to try. Very interesting….what are the dimensions/format? What is the ‘formula’? - ceramic magnets, winds per coil, wire type and size, keepers, etc etc? Quote Link to comment Share on other sites More sharing options...

What is the ‘formula’? - ceramic magnets, winds per coil, wire type and size, keepers, etc etc? I used steel cores with a diameter of 5 mm. Of these, I built coils with a height of 11 mm and a diameter of 13 mm. He wound a wire with a diameter of 0.05 mm, about 10,000 turns. As a result, I completely filled the coil, and reached the resistance of 2k5. The final resistance of the pickup when connecting the coils in series-in parallel came out 1k2. The capacitance was about 80 pf, and the inductance was about 1.8 Henry. This is ideal for preamp, it remains only to adjust the peak attack, which is also done in the original scheme. I used ceramic magnets. Since the standard length of the steel rod is 15 mm, taking into account the coil and the board, the gap between the magnet and the coil was 3 mm. This is more than acceptable. Although, even if the magnet was lying close, it wouldn't bother me 1 1 Quote Link to comment Share on other sites More sharing options...
Kiwi Posted September 2 Share Posted September 2 Just make some 5 string pickups in EMG/Bart format and tap into a new market. Ideally 16-17mm string spacing. Quote Link to comment Share on other sites More sharing options...

Yes, I am currently busy casting 5-string cases in p2 format (bartolini). I estimate the interstring distance under the bridge at an average of 17.5 mm 1 Quote Link to comment Share on other sites More sharing options...
Stas Posted September 2 Share Posted September 2 Since I cast the casings myself, it takes a certain amount of time, and is the most difficult stage. The height of the pickups eventually amounted to 25 mm. 2 Quote Link to comment Share on other sites More sharing options...
Stas Posted September 9 Share Posted September 9 Hello friends! In general, all installations are completed, and final conclusions can be drawn. These sounds rock the low frequencies very much. Despite the fact that I use the original Zobel filter, it feels great. With the tsobel filter disabled, there are so many low ones that you begin to understand the expediency of using it 3 Quote Link to comment Share on other sites More sharing options...

Stas Posted September 12 Share Posted September 12 Hello everyone I made a small video review, clicked the settings a little, I think everything will be clear 3333333 (video-converter.com).flv Quote Link to comment Share on other sites More sharing options...
Stas Posted Monday at 21:56 Share Posted Monday at 21:56 Good day to all! As promised, I recorded a sound comparison using a tsobel filter, and without. 1 half of it is with the use of a filter, the second half without it.
