I have seldom, if ever, been impressed by the sound of an aftermarket pickup solution for an accoustic guitar, at least not for Gypsy Jazz which is what I play. This came recommended by a friend who had bought one so I gave it a try on an Altamira M01F. Does it sound transparent and exactly like the guitar mic'd up? No ~ but it is way better than I expected. It has a perfectly usable tone, especially when used with a preamp and it has not turned the guitar into a feedback machine. I regard this as being a very useable and practical solution for playing live.
