    Hey all. I recently picked up an Ibanez SR 2405w, and I just had a quick question about the preamp. I generally prefer passive basses to active basses so I’ve been mostly playing this in passive mode, but when it’s in passive, the treble control becomes a tone control. On most basses, I play with my tone at 100%, however on this bass the tone control has a center detent. When you go up past the center it almost sounds like it’s cutting bass. So my question is, does anyone know how the Ibanez passive control actually works? Is it 100% in the center, or at max? Thanks for any info.

    My understanding is that in passive mode, the treble at detent is 100% tone. Past detent does nothing to my knowledge.

    I have 2 Ibanez basses which preamp's treble knob double functions as passive tone knob. But I've never checked how it really works when functioning as the tone knob.

    I'll check them out and report soon.

    See, that’s what I thought too, but both this bass, and the SR 1305 I used to own, got noticeably brighter past the mid mark. Too bright almost. There’s a lot more finger and string noise, almost like the difference between a 250k pot and a 500k pot.
