But this is the thing. If HX Stomp was really at risk of cannibalising sales of the HX Effects then Line 6 quite simply would not have released it. The people for whom HX Effects is ideal (i.e. folk who need more than 6 blocks, want at least one footswitch per block, don’t need amp models, have comprehensive MIDI switching needs, have amp switching needs, don’t need another audio interface and don’t need a headphone practice amp) are looking at HX Stomp with no GAS whatsoever.
People who willfully bought HX Effects but wanted the features of Stomp can cry “shafting” all day long. But if Stomp had been released first there would undoubtedly have been a ton of annoyed guitarists saying they had no need for the amp sims (because they want to keep their existing head & cab) , wanted more effects blocks, more physical footswitches, amp switching capability and scribble strips.
Line 6, and the music gear industry in general, will always prioritise the needs of guitarists over bassists. They outnumber us several times over. Arguably, when bassists look at the current HX options, the majority would gravitate to HX Stomp over HX Effects but Line 6 are more than aware that the vast bulk of their sales are from guitarists, so it made absolute business sense to prioritise the release of HX Effects before HX Stomp.
And yet, with all this said, looking at the bigger picture, both HX Stomp and HX Effects are primarily aimed at guitarists. Line 6 simply know that the portion of the guitarist market who have any interest in amp modelling whatsoever is relatively minute. Compare that to the huge portion of the guitarist market who have a serious interest in effects and pedalboards and it’s a no brainer. Anyone with any common sense would develop and release Effects before Stomp.
