Owen Posted September 24, 2008 Share Posted September 24, 2008 (edited) My friend has a TRB 5 and his pre amp is quite noisy. Is this par for the course? Edited September 25, 2008 by owen Quote Link to comment Share on other sites More sharing options...
The Burpster Posted September 24, 2008 Share Posted September 24, 2008 not sure but Techie is the correct place to ask..... Quote Link to comment Share on other sites More sharing options...
OutToPlayJazz Posted September 24, 2008 Share Posted September 24, 2008 Try changing the battery. Mine is as quiet as a mouse, apart from some obligatory hiss when the treble control is full up. Quote Link to comment Share on other sites More sharing options...
GreeneKing Posted September 24, 2008 Share Posted September 24, 2008 Yes my TRB5P is quiet too except for the treble issue. When the battery goes noisy is often the 1st symptom. Quote Link to comment Share on other sites More sharing options...

BOD2 Posted September 25, 2008 Share Posted September 25, 2008 Just a point worth noting ..... On a passive bass the "Tone" control can only cut and not boost treble, therefore it's common to play with the "Tone" control full on for maximum bite. On an active bass the tone controls cut AND boost. The neutral position (where the tone is neither cut nor boosted) is at the middle of the control's travel (there's usually a "notch" you can feel as you turn the control through this point). If you play an active bass with the tone controls full on (as you might do if you were accustomed to playing passive basses) then you will get a lot of noise as you are working at the limits of the preamp. The best way to get a good sound from an active circuit is to start with the tone controls at the midpoint. Adjust the amp EQ for a good basic sound then use small boost or cuts on the bass EQ to fine tune the sound. Quote Link to comment Share on other sites More sharing options...
