Anyone have one they like to use for switching in tweaks ?

Re: Fast relays
Are SSR such as those suitable for audio signals?

Re: Fast relays
MOSFET-output relays rated for AC are indeed suitable for switching audio. Triac and bipolar output relays are not.
The key factor is that MOSFETs saturate to a resistance, not a voltage drop like bipolars or to a diode like Triacs. The AC-rated ones have two MOSFETs tied source to source so the MOSFET body diodes don't mess things up. The MOSFETs are incredibly linear resistors for low currents, and probably good enough at high currents to switch speakers if you're careful.
Those particular ones may or may not be cost competitive or physically compatible. Mouser has a number of DIP-4, DIP-6 and DIP-8 MOSFET output SSRs that ought to work. They're in the US$3-$5 range.
Some pedal guys se MOSFET SSRs for switching.
