The Official Rumblekat Club

Hi Kats,

Recently purchased a nice red Kat. Love the tone and vibe. Easy to play.
I am getting a good amount of noise, from the pickups.
I thought it might be the tone pot...so I had that changed out...
But still have noise, when tone is above, say 2.
Anyone have the same issue with a possible solution?
Shielding suggestions....?

Hi, what I would do, it is semi hollow, chambered, is copper shield all the cavities. Then make sure all the shielding is connected and grounded to one of the pots. Good place to start

Is this noise that goes away if you touch the strings, the bridge, or the metal on the output jack?
 
The noise does lessen, if you put your hand on the pickups.
But not the bridge or strings.
It sounds like the bridge ground wire has come disconnected. On the RumbleKat (and on most Gibson basses), the bridge ground wire is held in place by one of the metal cups in the body that the bridge screws into. If the cups were pulled out previously then the wire may have come loose (the cups coming loose under string tension is a fairly common issue with that type of bridge). Lots of grounded shielding would negate the need of a bridge ground, but shielding the Rumblekat sufficiently may be difficult because of the hollow body
 
Interesting info, @sunbeast. I'm not having the noise issue mentioned by Russell G, but this is interesting to know. I changed bridges on my Rumblekat a year or two ago (to Supertone), and it sounds like that coulda caused a grounding wire issue, but fortunately it doesn't seem to have done so.

If you didn't remove the cups from the bass (which shouldn't have been necessary to add the Hipshot), then it shouldn't have caused an issue unless on your particular bass the ground wire was held into the front cup which the Hipshot doesn't utilize.

So I picked up the Rumblekat a few months ago to have something to try mods on. The Supertone bridge is already installed and I have some new mini humbuckers ready to go. Some new much needed tuners are on the way.

Where is a good source for new knobs? Thanks!
Got my knobs from Link Removed, For tuners Hipshot HB6 3/8 are drop ins, enjoy!
