  1. Non-inverting opamp, anyone? If the first stage is inverting, the input Z of the amp can be designed to nearly anything up to around 100 MOhm. By the way, how do you measure your amps' input Z and how much are they?
  2. Well, if the pedal has a jack, I would use screened. Then any cable can be mixed with each other. My exp pedal has so different looking cable that you cannot mix it by accident.
  3. Is it really? The text above mixes stuff quite some. The input is a modern opamp (which are usually FET-based) with very high input impedance. They do not load the source. In a signal line the source has to be lower impedance than the input, or the input will load the source. These opamps have so high input impedance, that they are practically invisible to any modern coil-magnet pickup, hi-Z or lo-Z. Even piezos. "Matching" is used in a funny way here. Bassist @Woodinblack uses lo-Z output to reduce noise and to ignore the load of the cable. High input impedance has nothing to do with that. Only if the input Z would be in close range with the source, there would be reduction of the frequency response. A modern opamp has an input impedance in the GOhm range. Your source, i.e. bass output impedance is probably ten to hundreds of kilos. Come on fellow players, this is basic electronics. Easy test of this is to bypass all hi-Z bass adjustments. This means those cheapo carbon track pots. What happens? Well, there will be more treble, as the pots load the pickups. Easy as that. Lo-Z electronics tackle this issue by using the pots only to affect amplification. The pots do not have to be in the direct signal route. Check John East's creations.
  4. The right terms would be that they turn high impedance signals to lo-Z. "Active" is not so accurate word here.
  5. If that amp has a FET-based input, it certainly matches any bass or pedal output. @Jus Lukin wrote wise words: active input is just a pad + that passive input. Many amps have good gain adjustments that cover practically all bass or effects outputs. Some hard loads (usually piezos) are hard for the preamps but most of these FET inputs can eat nearly anything.
  6. This is not an instrument, this is art.
  7. The seller may be the son of a hiram.k.hackenbacker Jr.?
  8. A '96 Dolphin, that is high end.
  9. I need to remind you of the several quality points within Wartburg. If compared with the same price points, then another story.
  10. I use my current rig practically everywhere. If I had some extra, my choice would be that small GK.
  11. Some time to write .csv files. Those are needed for a program, Mobile sheets pro to make indexes for big pdfs. I am leaving paper scores behind me.
  12. Is it better to be schitzophrenic than alone? Another forum gives a long ban for those who play with more than one account. For a reason, there are people behaving badly.
  13. Why, oh why do we get just another round of fenders. Sorry to say that I expected something more and novel. Great amps should equal great and original design in basses, too.
  14. As the editing does not seem to work always with Andphone, I add that I have had no issues with the strings if the thicker part reaches the tuning posts. But the measuring from the nut to the 12th fret is spot on.
  15. Very good notice @Smirfy I only use long scale plus or similar long scale strings as they fit every instrument I have. Longer fits always shorter but not vice versa.
  16. That's silica gel. They work for sometime but should be treated in an oven once in a while. Bass Player magazine discussed this and someone suggested alcohol based hand cleaners before the gig. They dry the skin somewhat and help to keep the strings a little longer bright. Beware of the ones that have some odor, or check that it is OK from your bandmates...
  17. If there is something you are not able to compare, it is the knobs. Depending on the designer the volume may follow the numbers, but usually not. You need some measuring equipment to define the output. If the gain is lower in another amp, the output is also much lower. Be open and use your ears while doing settings. Preamps have individual behaviour, and all settings are practically different. Show me two different brand amps that have similar eqs, and I will show you two similar 10" speakers... Don't even try, they just are different with similar marketing jargon.
  18. My basses (and some equipment, too) are from local shops, local players, as well as abroad (shops and individuals from UK, France, Germany, HK, Norway, Russia, USA...). My latest jewel is from UK. There are so few better basses in one country, that when you are after one, I do not see a country border as a limit. Usually few lines from the seller tell about the possibility to make a deal or not. Sometimes the seller does not want my money, and I can live with that. But most of the people are humble and honest players.
  19. Ned Steinberger told about the deadspots while he developed the L-2. He said he tried to reduce the effect and shaved a serious amount of wood from the headstock. It seemed that the deadspot (or spots) started to climb higher up the neck. He decided to cut the headstock off completely and the deadspot (or spots) went so high, they did not affect the sound anymore. His design is a classic example of the "form follows function". By the way, before you take the saw...
  20. Exactly. If you want to learn one, go ahead. The semiparametric preamp is very different to others in the market. The neck is stable. Warwick does not produce stable necks. There really is a difference. Weather, humidity, different string sets... no adjustments, no need to adjust. A bit different, but very functional high end tool.
  21. Some numbers: - bridge spacing 14 - 21.5 mm - scale length: 30 - 36", excluding fanned fret necks - nuts, yes, we are...
  22. How about 25, 26, or 36? Have to say that my playing rarely craves for 24 frets. 10 - 15 would cover most of my work.
  23. This is one very interesting way to handle the problems with strap pins: http://www.vigierguitars.com/html/Description_US/strap.html
  24. Very good point to use a luthier to make the connection secure. One loose screw and your dear bass is screwed. My preference is Dunlop as Schaller tends to loose at the strap end. And beware that the knob may drop. If your choice is Schaller, it is OK if you use a bit of thread lock. Dunlop on the other hand relies on Seger type of attachment. They may rattle, so some plastic or leather can be put under the strap side parts. I double check them every time before starting to play. It is important that they are pushed to the bottom of the strap pin (whichever the part is: there are two or three options).
  25. Do you mean 10 mA or 10 microamps? You certainly know this, too?
