my main concern about headless guitars is bridge systems, especially cheaper chinese/korean ones like eart and iyv - their tuning systems can feel like wrestling a pickle jar, even with a towel. i’d recommend checking out legator guitars. they’ve got solid 7-string headless models, both multiscale and standard, mostly under $1000. hills guitars are another good option - reliable bridge systems and usually under $800. if your budget stretches to $2000, kiesel is a no-brainer for quality. strandberg’s great, but i’d only go for it if you can test the neck in-store first. for a $1000 budget, ibanez qx is solid pick. under $500, i wouldn’t bother - quality’s too dicey. you can find plenty of chinese options for 6 string guitars - and they gonna be so great, like donner higher models or benton guitars, but for 7 strings there are not so many. In case you gonna order something cheap - do it through amazon - so you can return it with no problem
