Decision made, get it bought.

Got to say that the HD500x is a brilliant unit, and you can get some great sounds out of it, used one for many years before moving on to the Pod Go. The positives are that you can get some great sounds out of it, loads of options, good effects, loads of connectivity options. The negatives are that you have to buy the HD Bass pack, which gives really only gives you two amp models (and two variations of the SVT), and two cabs. The effects are guitar specific, so for a decent drive sound, you need to create a parallel path, one clean, one dirty. It's not small, and compared to the HX model set, it does sound dated. Amp modelling is good to have, something like the HX Stomp or Stomp XL might be a good option if you use loads of effects. If you're after a "core" sound and up to 3 effects, then think about a Pod Go. I do think that you'd definitely need to reconsider the HX FX if you like your amp setup.

If you really liked the HX FX, then why not get another? At least you know what you can do with it. I know, bad experience with one unit can make you wary, but if it works for you, it works for you. Just a thought.

Attenuators should work for both guitar and bass amps, AFAIK, they only regulate the signal being sent from the power amp to the cab. However, they should only be used on amps that have a Valve driven power amp section. A quick Google search of the Mesa TT800, shows that it's a Class D power amp, so therefore you don't actually need an attenuator. The TT only has valves in the pre-amp (3x 12AT7). The attenuator works to maximise the signal into the valve power amp, but reduces the signal into the cab, without damaging the transformers & power valves in the amp. It allows the power amp to be driven into distortion, which is a smoother and clearer sound than pre-amp distortion, which is "spiky" and can make the sound somewhat "mushy". Basically, you don't need an attenuator unless you're using an amp with a valve power amp stage.

Didn't @stewblack get someone to custom build a multi-fx pedal a while ago? EDIT: Found it - Lunar Cluster Surely, something like the Tech21 Bass Fly Rig v2 or the Valeton Dapper Bass would be a great reference point. Personally, I really can't fault the Pod Go. Yes it's limited. No, I'm not using all of it's capabilities. Sounds great though.

IIRC, I had loads of trouble registering on the Line6 Ideascale page. And to be fair, any ideas that are not hi-gain boutique guitar amps don't really get many responses.
