Been using a Stomp since they came out - never had any trouble with DSP for bass. Rhythm guitarist on one group I'm in is using one and he has added one or two extra pedals to free up DSP, but he's happy with it. As for signal to FOH, @micguy is right...line level works like a champ with the HX stuff, but I like to add some extra oomph, so I send it to a LBA TI Box then FOH. If you want to pull double-duty with the rig and money is no issue -- Fractal Axe FX III. The lead guitarist in one of my groups has one, and he and I both can play through it simultaneously. I have a super sick sounding Orange AD200B + 8x10 OBC patch dialed in. I just bring my bass and Effectrode LA-1A to put in front of it... good to go. TBH though, he has a relatively simple signal path, so I cannot attest to how much DSP we're burning with both of us playing at once, but I've never heard any latency, freezing, ect.
