I've got the Headrush Gigboard. I was looking at the HX Stomp, but for one patch covering 90% of my sounds I needed four switches. And then the Headrush came up on Andertons for £350, ex-demo, so I thought I'd give it a try.
It's so easy to use - it's got a big touch screen where you can tap on empty blocks, select what you want to go in, drag them around to change order, etc. Then there's one big knob (😐) to help with fine tuning where dragging your finger across the bar isn't giving enough control. Even when playing live, you can switch between modes, through patches, control the looper, etc, with the foot switches.
Easy to use - you don't need to set it up patches on your computer, just plug in your bass and speaker/headphones and off you go.
Quality of sounds. It's great - after coming from a Zoom B3 this sounds so much better. The octave tracks really well, the distortions sound aweome (I've split my sound to have a distorted guitar amp mixed with my bass amp), everything can be tweaked to what you're looking for.
Very customisable - one switch can control a single effect, or multiple effects & amps etc. Different signal paths options.
USB audio interface - record direct, or record clean and re-amp later.
Ability to load IRs (the Markbass 212 sounds way better than the default cab sims to me)
Exactly the same abilities as the big Headrush Pedalboard, just less switches and I/O. You can still add a separate expression pedal.
Very guitar focused - Only a couple of bass specific amps (mostly Ampeg) and effects compared to 30+ for guitar. However, the ones it's got are all I need, and I've never not been able to find the tone I'm looking for via a combination of amp, EQ, cab or IR.
Limited effects list compared to the B3 (though most of those I'd never use. All of the Headrush effects are usable and sound good).
No DI out. At the price, and sound of the unit, I'd expect one. Maybe because it's guitar focused?
Cost - this goes for all of the multi effects / amp modeller pedals, but I'd struggle to justify the £500-£1500 for these Helix, AxeFX, Headrush pedals for my limited use of a couple of tones, a few effects and something to practice and record through. For a cover band guitarist with patches for every song, I can absolutely see the value. At the £350 I paid, I'm very happy with it.
