Hi Dom, that's interesting, I haven't watched this video for a long time, you're right there seems to be loads of distortion at the end. I'm sure when I did the video it wasn't like that at all. I wonder if youtube have changed the levels at the end somehow? Strange.... thanks for pointing it out.
Mine was much worse than yours and I was convinced that the pot was going to need replacement but the switch cleaner fixed it 100%. It's a really expensive bass with nested pots so I wasn't looking forward to the repair bill, so thank you ;)
Just did this on my '87 Charvel 3B. My guitarist buddy thought I was going to have to replace the pots, but this procedure has them good as new! I did remove the pots from the body as I was concerned about getting the contact cleaner on the wood.
Going to Radio Shack tomorrow, buy a can of compressed air and some contact cleaner and try this on a bass that has this exact issue. Thanks for the info!
Oh my goodness, this is the exact same circuit board as I have on my bass. It's a Samick. I'm trying to refurbish the body or rather build a new one, but I couldn't figure out the circuit board.. Does anyone know where a wiring diagram is of this
Hey there, thanks for the video, but I think I might have another problem...My Ibanez sr505 isn't making any sound when I'm plugges In. I'm missing a tone knob but I think the real problem is that my volume knob is loose. I opened up my bass and saw that the volume pot (that's attached directly onto the bass) is loose. Any tips on how to tighten it? Thanks again!
Hi, thanks for the video. Could you please specify what is the particular circuit board name/model? Im trying to find one and replace on my bass. Thanks
David Donoso Good question. I'm not sure! It's the stock one that came with the bass which is an Ibanez CT series. So I'm guessing it's their own in house circuit board. I would recommend if you have the budget: John East, Aguilar, or Bartolini. Their are probably lots of other good ones out their too.
Sorry didn't read before! I have an Epiphone EBM-4 with the same circuit, could you tell me what does each knob do? I have a pot that turns the whole circumference and it only sounds on specific points. How hard you think would be to change a pot from this circuit board?? Is there any way to know if my cables are in the right position on the pins?
I think the controls are: Volume, Blend, Bass, Treble. It sounds to me as if the knob that turns all the way round is faulty. You can check out another video I made that shows replacing one of these pots. That may help.
hai thanks for video , i want to ask about pickup and pots wiring, is the voltage of caps like an 160v&200v&400v&600v take effect or not for sound or its important influence or notthing???
+Julio Cavalera as far as I'm aware it shouldn't have an effect as the circuit is only 9v or maybe 18v in some cases. The voltage is the maximum it can handle. So if the circuit is 9v then a 25v capacitor or above should be fine to give plenty of headroom. A capacitor with a lower voltage would be a problem though. I'm not an expert in this area though. So you may want to do some more research too.
pauljazzbass thanks, but i mine is on a pasive guitar and bass wiring , couse i read on every caps must been writes voltage capasity like 022j 400v and the other how about that?
Ben Hearn Interesting. WD40 is good for lots of things, including removing sticky residue from labels. It doesn't evaporate like contact cleaner though. I think it's oil based rather than alcohol based. So probably not.
+Ben Hearn Anecdotally, I've used WD40 to clean some dusty connections in a pinch, but the crackles came back relatively quickly. It can also 'gum' up your stuff.
Do you think it'd be worth doing on a bass where the problem seems to be gone beyond just crackle? Essentially there's only one position on each pickup volume knob that works, apart from that it'd appear that they're disconnected, though obviously they're still connected. Any thoughts?
They probably need replacing. You can usually find their values written on them (something like 470ohms). If you solder in new ones of the same value you should be fine. (also look out for the letter a or b (this is to do with it being logarithmic or linear), you don't need to know what it is, just buy one with the same letter.)). Hope this helps
i never use compressed air on any electronics again. i ruined my beamer and my drill with it. if the pressure is to high you will losen cables . also pushing dust deeper into the parts isnt really a good thing to do. nice video thanks for sharing
hi there. I have an rbx 170 and i need to take it apart but im afraid i wont be able to put it back together (after painting). can you help me out . give me a few tips or upload a video . I need to know what the easiest way to do it is. Thanks :)
The approach I use is to be very methodical. Take lots of photographs of it before you start. Close ups of bridge, electronics, tuners etc. Then take apart: strings, neck from body, then proceed to take hardware off the body (have lots of small bags (food bags will do) put screws in them and label them bridge, neck, electronics cover, etc. You will need to unsolder the pickups - label each wire and where it comes from (take picture too) put tape on the pick ups and label them, use arrows to show which way is up and label which split coil is near the bridge. Hope this helps
I think its hit and miss with some guitar shops. Many of them do have very competent staff who could do it. Anyone with some basic soldering skills could do it though, its not too difficult if you can do a bit of soldering.
Haven't done a video on that (yet maybe!). As I understand it, because of the pickups being a single coil you will always get hum particularly if you solo (use) just one pickup. If both are used and they are wired to cancel the hum it should reduce it. Putting copper sheild tape behind the pickups and in the control cavity may help a little. Or maybe if its only noticeable when not playing, use a noise suppressor on an FX pedal.
Do a search for "Copper Foil Tape EMI Shielding" this is the stuff you'll need, it has conductive adhesive backing, and you can solder a ground wire to it.
Pretty sure it is a Samick circuit board originally. Just bought a Samick Thunderbolt bass from 94 with this circuit board for $75 Aus, no output though. Going to be a pain with that circuit though.
Is it normal for the dust to return a week after each cleaning? I only get about a 4-5 days of crackle-free pots out of every cleaning. Is that normal?
+gxtmfa hi there. It has lasted longer when I've done it. But I've noticed that eventually the pots need replacing. I'll be doing a video on this soon. It also depends where you keep your bass. If you put it in it's case whenever you're not playing it then I've found it to be ok. This is how I normally keep my basses. The one I leave out which I use when I'm teaching does suffer from noisy pots a lot. Hope that helps.
noluopanpa If you look carefully you may find some residue on another component where the wire has come from. If its passive try looking at the back of the pot, ground, screen wires are often soldered on there.
Good advice, I prefer not to use compressed air as it tends to push dust into the pots. Finish off with a precision plastic safe lubricant like CRC 2-26, A little dab will do yah.

Is it intentionally distortion from the amp that I can hear during the end demo?

@@pauljazzbass You're welcome. Seemed slightly ironic to have intentional crackly from the amp.

Thanks for the information. I'm learning how to clean and adjust my instruments.

I got that scratch on my yamaha bass. Going to try your fix bro. Thanks!

+Julio Cavalera. I would think the voltage doesn't matter. The uf value microfarad or picofarad is the one that matters.
Thanks for the vid. Do you think WD40 would work in place of contact cleaner (just trying to use up what I have got around the house!)
Ben Hearn Interesting. WD40 is good for lots of things, including removing sticky residue from labels. It doesn't evaporate like contact cleaner though. I think it's oil based rather than alcohol based. So probably not.
Thanks for a quick and helpful reply! I won't use WD40 then. Subscribed. :)

ok then . ill do like you said. But what if i cant solder the wires back. Do you think if i took it to a guitar shop they could do it for me?
I think its hit and miss with some guitar shops. Many of them do have very competent staff who could do it. Anyone with some basic soldering skills could do it though, its not too difficult if you can do a bit of soldering.
ok thanks alot . i appreciate it
Really great video man !
But have you got something against the hum on jazz bass ?
Thanks

If both are used and they are wired to cancel the hum it should reduce it. Putting copper sheild tape behind the pickups and in the control cavity may help a little. Or maybe if its only noticeable when not playing, use a noise suppressor on an FX pedal.
Thanks so I can put aluminium paper for example ?

One of the guitars cable severed and i dont know which one it is. Could you help me ??
You keep it simple and like that a lot
+Dwain Artistrain thank you.
+Dwain Artistrain thank you
I'll try on my bass!!! Thanks for the video!! Thumbs up !! :)
Hope it works for you.
what is that spray device called
I used a compressor.
Super useful. I'm going to try this later!
Hope it works for you, too.
Is it normal for the dust to return a week after each cleaning? I only get about a 4-5 days of crackle-free pots out of every cleaning. Is that normal?

My bass always distorsi, how can i get repair.
It could be a number of things. Try using a different amp and different jack to jack lead first. If it is active try replacing the battery.
Hey ! One of my wires severed. Could you help me ??
noluopanpa If you look carefully you may find some residue on another component where the wire has come from. If its passive try looking at the back of the pot, ground, screen wires are often soldered on there.
Yay ! I made it :) thanks.

What is that circuit board in your guitar man?
+atrothe hello.. Its the original one that came with the bass.
thanks :)
