S-PRE-2
#3
A brief update...

Everything works.  Have had it for now just sitting between my bass and my Scarlett/computer, which is my practice setup, playing around with tone.  So far very very happy with it.  Of course haven't gigged with it yet, or even played with other people, but I expect good things.

Next question:

I have now purchased an ICEpower 125ASX2SE, which is a 2X125W digital amplifier which I'm going to pair this with to make myself a hybrid amp head.

Looking at the documentation for the amp, it actually looks like it can also be configured as a 1X450W output, which is an intriguing option BUT it needs a balanced signal.  I can, of course, just convert the unbalanced output from the S-PRE-2 to a balanced output using the normal kind of methods (like a transformer) but I wondered if there was a way to mod the preamp to output a balanced signal without the conversion.

That all being said, now I think about it, I was going to be adding a Jensen output transformer to give me a DI out anyway, so I could just tap off that to drive the amp if I wanted to drive it mono.
