I'm not musical expert, but overall, it didn't give me what I needed. Playing guitar through this is not quite what it's made for (imho), especially when it's then heavily distorted. It's very rounded. Maybe for clean guitar - a different story, but I also compared it to HA73 EQ which costs less and offers way more sound shaping functionality - that one you can buy and be more ensured that it will be used for more use cases.
Singing was a secondary thing for me, so I didn't tried that since my primary need is not met.
Trim has nice feel and a small notch in the middle that helps to feel where "0" is.
