To be safe, use the DeOxit 5. it only takes a very small amount in the correct spots.

Open the box and try to spray a cleaning/lubricating solution inside the volume pot mechanism like Deoxit D5, you can also spray a little of it on the output connectors where you plugin your cable that runs to the amp. If that doesn't solve your problem you have to replace the volume potentiometer. The machine I have had similar issues and I was lucky to have a pot close in size and resistance value as the original which in my case was broken, so I just replaced it. Good luck!

Fultone FB-2 does not boost very well all of a sudden. Pot sounds scratchy. I cleaned the pot, still sounds the same. and still little or no boost.


I hope you did NOT use contact cleaner in the pot... Use CRC226 available at Home Depot in the electrical dept. Contact cleaners like Deoxit or Blue Shower destroy the lube in the pots. Check the battery or adapter for the unit.

When I use the Master volume the amp will suddenly bypass the master volume. And when I play on the top boost the volume fluctuates by itself. Thanks for your help Devon


I suspect you may have either a circuit board crack or the volume pot is bad or soldering of it is bad. Vibration will make things come and go. Look for broken solder around the pot leads first. Then look for a cracked circuit trace on the board near the ground end of the volume pot. If you put cleaner in the pots NEVER use Deoxit or Blue Shower. Use CRC226 which is available at Home Depot in the electrical dept.

After several months of being stored i used my roland juno D to find that some of the keys didnt work. I cleaned the rubber contacts etc but they still dont work? and the ones that do are uneven volumes...


Did you clean these contacts with ONLY isoprophyl 99% alcohol and Qtips? If you used another product you may have spoiled the contacts. Also did you clean the circuit board where they contact with the same product?

If you used another cleaner, best to redo your work... quickly... Contact cleaners such as Deoxit and Blue shower destroy this type contact.

The volume control on my Gorilla GB-30 amplifier crackles when turned, but the actual volume never changes. Will a new control switch fix the problem? Are manuals available?


There likely is another problem, possibly a cracked circuit board or bad solder at the control. If the control worked at all, there would be some change in volume. Take unit in for repair.

Roland juno-d, keys are either too loud or too


Normally you have to clean the conductive rubber "pills" AND the circuit board traces they get pressed down on.

USE ONLY 99% isoprophyl alcohol on Q-Tips to do the cleaning and be gentle.

Use of other product like deoxit and other contact cleaners will wreck the contact material.

Volume control pot is bad. Tagged VR1 on PC


Before you replace the pot, try cleaning it. Use electrical contact cleaner such as:

- CRC QD Electrical Contact Cleaner (available at many auto supply stores) - www.crcindustries.com
- Caig DeoxIT (available at Radio Shack and electronics supply stores) - www.caig.com/

Spray the cleaner liberally in the pot (spray where the shaft meets the pot, and if possible, into any holes on the back of the pot), and rotate the shaft repeatedly. Repeat several times.

If the pot is still intermittent, it can be replaced, but you need to replace it with a compatible part, and the job will require some soldering skills to prevent damaging the rest of the circuit.

Make sure you get an appropriate replacement. You need a replacement pot with the correct resistance (measured in ohms) and taper (linear or analog). Typically, the value of the pot is marked on the back, and will read something like "103A" or "10K - B". 103 or 10K indicate the resistance in ohms, and "A" or "B" indicate whether it is linear or audio, respectively.

Your best bet is to desolder the part and take it to a local electronics store for a replacement. If no store is available locally, replacements can be ordered from online stores such as:

- Mouser.com
- Jameco.com
- Digikey.com

Feel free to post the numbers on the back of the pot if you need help locating an appropriate replacement.


(Note that the convention for labeling taper has changed over time - getting the wrong taper should not damage the equipment, but will probably result in the volume control to seem "not smooth.")

A ''static'' sound coming from ALL outputs of Korg Triton


try cleaning ALL the contacts involved with Caig DeOxit (D5, S5. F6, G5, etc.) products*, they work very well. e.g.; cables, inputs, outputs, and (if you're confident) all the contact points "under the hood". this static you speak of sounds like less than stellar contact points and can addressed at home if you've the motivation to DIY.
