East Pre question

Recommended Posts

Any advice out there for this?

i had an east custom pre for my shuker jazz last christmas, put it in the bass, no problems. seemed ok at the time. Had a another bass shortly after which i have gigged non stop since. Just got into playing the jazz again, as needed a different sound for some stuff i was doing. The preamp sounds amazing, mega powerful and tons of sounds. But now there is a non stop buzzing in certain set ups...

the config is:

3 stacked pots -

blend/volume
bass/treble
mid cut boost/freq

then a pull pot -
master tone/pull passive

The problems seem to centre around the pull pot
when the bass is in passive mode its completely silent with the master one all the way down, as you bring up the master tone the buzz gets steadily louder.
in active mode, the same really, accept the buzz is so loud theres no way i could gig with it.

with the master tone knob all the way up, if you bring the treble control down the buzz goes away. This isn't true of the bass in passive mode though, the buzz remains.

and finally, touching the knobs reduces the buzz, sometimes slightly, and sometimes all together.

I know this all sounds like grounding issues, and believe me i have hunted low and high for a problem with the Ameter, but cant find anything. i've run extra grounds to the body shielding from the two troublesome pots to know avail. Unfortunately because of the way the pots come (all special and connected with that lovely multiwire papery stuff (no idea what its called) i cant test it with other pots... and its driving me mad cuz if you ignore the buzz the bass sounds class!!!

anyone got any ideas? could i need a replacement pot of some sort?

There is a simple fix for this which John can provide in the form of small springs that fit between the upper and lower knobs to complete continuity and stop the buzzing. john will help you with this don't worry, its a known issue.
tap up John he's extremely helpful

You'll find him in the affiliates section.

From memory, it goes under a stacked pot. The instructions are online and give details. I understand that it grounds the pot.

Put the springs under all stack pots and that will do the job but make sure you put them the right way up, widest part of the spring at the top bit like an upside down pyramid if you get my drift.
