No problem.
Funnily enough, as I posted that last reply, Ryan @ Fuzzrocious tweeted about active basses and effects, to the tune of "sell it and buy a passive" haha.
I run everything totally passive, but then there are plenty of excellent 'effects' players who play active, Justin Chancellor & Janek Gwizdala being a prime example (Wal were 9v pre's).
I've not tried the ARC, but being based on the old Tall Fonts is a Silicons (more compressed), with a diode lift option (probably more gainy). The Stache, being based on the later Muff, with the Germs will sound a bit quieter, warmer ('vintage').
I tend to run my Stache in the assymetric LEDs setting (I have LEDs, Germs, Assymetric LEDs), which is massive!
But then I run my Rat Tail with LEDs too, so I must just like them
Juan Alderete did a great Fuzz Wars series on his website which outlined how each Fuzz is very different, some benfit from a hard touch, others blossom nicer with a soft touch. Obviously a higher output bass will make a soft touch harder as the signal is already pumping out. As Ryan said above, perhaps turn your bass down and your amp up
