Hi y'all - just a piece of advice needed from anyone with superior electrical knowledge than me (not difficult)
I have a mz2 with a bust level pot - anyone know where to get a replacement and how hard it is to replace ??
Also i have an old cube 40 amp stashed in my loft that i bust out last week - its very crackly on almost all the controls and both channel inputs and pretty poor - need to wiggle them to get a constant signal then tiptoe away and hope it stays. I was thinking of spraying it with an electrical contact cleaner but read somewhere that sometimes this can make them worse ???
I know i used the maplin contact cleaner on my old marlin sidewinder and the 3 pots froze solid so dont want to make THAT mistake again.
Any advice greatly appreciated - remember please that im a bit of a novice and have only swapped pickups and pots on guitars in the past so the simpler the better !!! |

Hi fragsie
Email the guys at SmallBear electronics in the USA
They will have something they will recommend, & these guys really know their stuff.
You may find that the stuff they recommend is available in your country.
Send them a detailed description of what you want to do, & let them also know that the stuff Maplin sold you didn't work & what & why.
Also tell them that you are reluctant, after what happened after your bad experience with the Maplin product.
It's difficult to recommend anything, as I am not fully aware of that is available, in your country.
I have used one of the Electrolube switch and contact cleaners, that is imported from England, but I can't remember the exact Stuff.
I use a product from a company called CRC.
The best stuff is no longer available, because it might have caused some people to pass out, after inhaling its fumes.
Regards Dr. Bob  |

I've got Maplins contact cleaner, it seems safe enough.
Maybe you sprayed a little too much in there and literally froze the pots solid? Contact cleaner is an ice-cold spray because of the contents & pressure, if you've ever sprayed your fingers by mistake you'll know. I'm surprised the pots didn't work after returning to room temp though. Maybe the pot contacts are 'off the rails'? By that I mean the knob has been turned too far at some time and the circular metal contacts inside have jammed, they could maybe be fixed if you take them apart.

| You might want to try Rapid Electronics for a replacement pot. They've got some 16mm pots with splined shafts. Roland will have them but Rapid will probably be cheaper. Can't remember the value of the MZ-2 pots but the schematic can be found on godiksennet or freeinfosociety. |

Thought I was able to help as I have a gutted ds-1 on hand and send you the pot for free. I already used the 100K pot from the Level in my crybaby, and still have another 100k pot. When i dug it out, turned out its a 100KB linear pot from the Tone knob.
The MZ-2 lvl takes a 100KA...audio
heres a link to the MZ-2 schems if you don't have them.

good luck
