Thanks all for the responses and sorry for the slow answer; it's been one of those weeks!
I have a HXFX with a Tonex pedal, so capable of generating sounds that are good, but I am really struggling to do so. Having spent years playing with guitar amps, I know what sounds I like & how to get them. Being a lot newer to bass, I am still unsure about what sounds I like, still less on how to get them & my current setup relies on a bit of know-how., which I just don't have. I have a couple of nice sounds that I like, but just upgraded bass and now they need rework again to work with the new output.
Worse still for band mate with a very, very guitar amp pedal in his rig. Hence the idea of the shared bass pedal.
So whilst I could get the sounds from the current rig, I am really struggling to find the time when I actually want to spend more time playing and getting better technically.
The idea is to have a bass channel going straight to mixer and 2 guitar channels (there's 2 of us and 8 channels, so not an issue for the mixer), with only 2 being live at any point.
In terms of what I want is the ability to be able to switch between a few different sounds. We don't need to change mid-track, but 5-10 patches to cover all our songs will be more than enough.
Not too expensive is def <£500 & c.£300 is ideal.
& @tauzero WRT to the B2-Four, my understanding of that was a horrible display and not the same sounds as the B6, but I am trying to read everything and treading new ground, so happy to be corrected! I think this review of the guitar equivalentreally made me think I needed to spend more: https://guitar.com/reviews/effects-pedal/zoom-g2-four-g2x-four-review
Not sure how valid that is for the bass version, mind, but I am lucky enough to have the room to get the B6, if it's an upgrade....
Saw that the ME90b is out too, not sure how useful this is, I didn't like the ME80 much, but this is many years on. I have spent a fortune over the years buying the wrong guitar kit and selling it, so trying to take my time on this one & TY in advance for the input!! 🙂
