OPA4134 - what should I build?

[ftumch]

Got one of these bad boys lying around and I don't know what to build with it - any recommendations?

I tried it with a Belton Brick but the hiss was murder - I put that down to the extended frequency response

Maybe an OD-1?

Parhelion Vintage Overdrive / BOSS® OD-1 Overdrive

A precursor to the Tube Screamer known for being the first overdrive effect to utilize diodes in a negative-feedback arrangement for clipping purposes.

Like the TL074 and other quad amps its often used in multistage preamps and equalizers.

Phonopreamp. By far better harmonic distortions than the TL074.

Something along the lines of hifi, such as an EQ or compressor or preamp — waste of the chip if used for a dirt circuit. YMMV

Definitely. TL074 is general purpose, NE5532 (dual OpAmp) is Hifi, OPA4134 is HighEnd.

OPA2134 is SUPPOSED to be superior, but the distortion profile of the NE5532 is still better, old but gold
