バイパス音と未接続の音が変わるのが気になるならMXR、バイパス音とブースト時の音のタイプを揃えたいならFree the Toneという感じでしょうか。 とはいっても、ここに更にエフェクターを繋げたらどうしても音は変わってくるだろうし、そこも含めて考えると選択肢も変わりそうですね。 あとは動画で解説されていたように、常時ONの使い方をするかどうかという部分で考えてどちらを選ぶか決めるとよさげですね。
Nice video Sir. *sorry for my English. If you use a hollow body guitar or LP type guitar like me with a little bit beefy sounds PUs (I use IBJL Epiphone Casino with Gibson P-90s & Burny humbuckers LP Custom with Bareknuckle The Mule) I think you're gonna like the Final Booster : chimey/jingle jangle all the way with a bit of hi-fi sound mix with the feel/mojo of analog/vintage/warm too, it have a special sound indeed. Very good oomph too if you use non-clean sound with it. I think it's not a super transparant booster but the sounds have a trully presence or brilliant quality/non-muddy, like a good old non-master volume Marshall and Vox amp. I have a Dunlop Echoplex Preamp and this one too have an excellent quality & quite dimensional sounds.
