Default What's nicer than a TL062?

I have a bass (guitar) with an active circuit. In fact it uses 4 TL062 SOICs. Is there a nicer JFET Op amp that I could use? Its battery powered so I can't go thowing power at it.
I've down loaded the data sheet but to be honest I could compare it to other amps but I don't know the most important perameters.

Yes, in fact me too have replaced a TL072 in a guitar preamp, and it's not so easy to obtain good quality without big power consumption (maybe that's related to transistors operating point a bit hotter to reduce distortion). I've tried NE5532 (little better sound, little more power), TL082 (bigger change in noise, power like TL062), and LF353 (I don't remember the number, that was very hi-fi sound and big power draw). At the end we stuck an old 741 in it and the guy liked it so much that he could ignore the big hiss. It was even microphonic... Don't know how this can happen (I've made pretty good joints) but the chip itself was microphonic. Not related to capacitors/resistors/other things...

Yes they are a tad less noisy than the TL06X series... And also a bit less battery-killers.

For me the best is LF351 that have fets on input, I compared it with other chips (Ne5532/34 Tl071/81 ecc..) in the same circuit.
Also LF356 is OK infact it's a double LF351.

My 2 cents.

Oh yes it was the LF356, not the LF353 as I said in a previous post. I quite like it.

Perhaps I am reading the specs wrong. ( Why can't they write them in a standard format?)
TL072 = Icc 2.5mA 3.5Mhz
AD8032 - "quessent Current" 1.4mA 30 Mhz
TL062 Icc = 0.25mA 1Mhz
LF356 = 3.4mA 50 Mhz

True it was audio that I am looking for but the TL062 has a battery consumption nearly 1/6 of the nearest rival.
