Epiphone Tobias Toby IV has some electronic problems.... Can we fix it?

- This bass guitar had some Signal to Noise ratio issues. Basically, it was sounding weak, and there was significant noise.
Let's see what we can find out and fix.
As of Dec 2018, the bass is still working well. Looks like the original factory assemblers were being too fast with the soldering irons, and not careful enough. I still find the onboard pre-amp to this a little on the noisy side, but it's a grand improvement from where it started.
BIG THANK YOU. For this video.
I had the same issue. My battery holder came loose and the red wire broke.
I had no idea where it was connected.
I had the feeling it came from green board but but was not sure.
I did not do a neet job like you with my bulky solder gun but it worked.
I do not have the same black coating inside the cavity. The paint guy was probably off that day :(
Glad it helped. Some instruments, you can get the wiring diagram online, and that helps.
@@DeadKoby my toby doesnt have a battery and i dont know why..and if it does it isnt back there
Thanks for the video, gave my a good head up on my newly bought Toby bass, which as the exact same issue!
Good deal. The repair has held up, as this Bass's owner has been playing it regularly since... I got to play with him in the band today actually. The most likely culprit is the wiring on the compressor/amp board. The "loose ends" on the ground shield, or the battery wires are a potential short to the battery, then everything just goes out. I have a "real" Gibson made Tobias, and this budget model has the same great neck profile. This Epiphone Toby is a really nice playing bass. With proper setup, it's one of the best low price basses I've come across. For under $300 US, it's a bargain.
I've wanted to install these pickups and wiring in a project jazz bass. The problem is that both pickup housings are slighly longer than a regular jazz bass pickup
and the bridge and neck pickups are exactly the same dimensions as each other. The bridge pickup routing has to be modified to make it fit. The standard Toby 4 has passive bass and treble cut/boost controls that don't require a 9-volt battery. It's like an active preamp that isn't active.
I had problems with excessive battery consumption. So I replaced the input jack and the problem was solved. The bass worked beautifully for about a year. Then yesterday I changed the battery, saw a spark, and now the bass makes a lot of background noise and the volume is very low--any similar experiences?
The battery positive was broken when you opened it therefore disabling the preamp. And you're right, the wiring should not have been left loose the way it was. As for the pickup leads, if they were cut too short that could prove problematic should they become disconnected
Thanks mate for the video and experience
I hope it helped you out a bit.
@@DeadKoby I got one but still New do I need repair it like you did?
It's conductive paint. It creates continuity with the foil on the back of the control cavity cover and boom, faraday cage.
Cool I should have put a meter to it... Once I figured that the solder station was the big noise source, it was all downhill. The wiring job on this was not tidy... at all.
My on-board preamp is mess up. Anyway I can get a replacement?
Would you be able to install an active/passive switch on one of these Toby basses or know where a schematic is that would work thanks? Great video!
It should be possible to do so. I don't want to draw a schematic that can't be tested though.
What happened to you with the bass and soldering iron happens to me as well. It also happens with humbucker equipped guitars
I'm just glad I got it fixed for the owner. He's been playing it now for a few months since, and it does NOT "eat" batteries like it did, and the pre-amp circuit continues to function.
Hello... Thanks for the video... I have two questions, could you help me?
1st - Do you know what is the specs of that blue potentiometer? Here, this Toby has a lot of noise while you rotate it...
2nd - Do you agree it would be possible to bypass this circuit and use it as a passive bass with the reamaining components? Thaaaanks!!!
Try spraying some contact cleaner in the pot and rotate it lots.
Getting rid of the paint on the bottom of the bridge will solve this problem and improve the sound.
It's working OK. A fellow band mate played it today actually.
B+=battery positive.
I swear on my life,!!!!! mine had hot glue used on it frm the pickups to all 4 pots and Bord im n process of fixig it
Whomever was in charge of electronics on this model needs to be replaced.
0:30 a *WHAT*
The Electronicals? Yeah, it's an "ism" I use sometimes when I'm working... Fix the Mechanicals and the Electronicals. Stick around and you'll learn other ways to talk wrong.
@@DeadKoby not this u called it a guitar I was dead laughing
It's a bass guitar... I own 4 of them. I don't work with a script.
@@DeadKoby I was kidding
No worries........ Hopefully we all learned something from this experience. The owner still plays this BASS most every week. (I'm on drums)
Electronicals???????
Sure... Mechanicals and electronicals..... Its a new word I invented.
Kinda sounds romantical.
You may not have heard of testiconicles either!
Is...poo

YOOGE.
