<div class="bbWrapper">Hi,<br /> <br /> Recently installed Aguilar MM4 pickup in my Stingray bass.<br /> Pickup sounds great but when I&#039;m touching pole pieces while not touching strings, I get a loud buzz. When I touch strings the buzz disappears. There is also electric &quot;click&quot; sound when I touch strings or metal parts.<br /> What could be the problem?<br /> <br /> Jarkko</div>
 
<div class="bbWrapper">Are you still using the original preamp, or did you swap that out as well?<br /> <br /> Sounds like something wasn&#039;t hooked up right.</div>
 
<div class="bbWrapper">It&#039;s original preamp. This is 2005 Stingray and had problems with original pickup so had to change it.<br /> The buzz disappears when I touch strings but there&#039;s slight delay before buzz &quot;fades&quot; out..</div>
 
<div class="bbWrapper">Just can&#039;t remember if the original pickup did the same. It just lost its power.<br /> Are Stingray pickup polepieces normally grounded?</div>
 
<div class="bbWrapper">.<br /> IMO you have a grounding problem (earth connection) with the electronics.<br /> <br /> Trace the preamp wiring. Look foe loose or adrift wires. <br /> <br /> Customer Service can provide a schematic diagram and advice if needed. <br /> <br /> Email CS here:<br /> <br /> <a href="mailto:[email protected]">[email protected]</a></div>

My previous Stingray had problems with input jack, could that cause this kind of problems.</div>
 
<div class="bbWrapper">Received a wiring diagram from Ernie Ball. Great customer service.<br /> We have gone through all wirings and it seems that they&#039;re ok. Do original Stingray pickups have grounded polepieces? Could it be that Aguilar doesn&#039;t and that is causing the buzz. Just guessing...</div>
 
<div class="bbWrapper">No idea. If you still have the original pickup you could always send it back to EBMM for repair/replacement.</div>
