This is a ramp specifically designed for instruments like Sadowsky and other types with a wheel at the neck end. We often receive requests for production for instruments like ESP's AMAZE and AP, and we can accommodate them. This listing also supports 5-string models. A truss rod adjustment opening is provided, but full-covered processing without it is also possible. Full-covered types offer advantages in terms of appearance and playability. However, you will need to remove the pickguard when adjusting, so an open type might be better for instruments with necks that move a lot. We custom design based on individual size confirmation (^^) However, recently, various manufacturers have released models with unusually low neck-end heights. We also manufacture various other tools, and offer a small discount for combined purchases.
