It's a different style compressor than the Dimond, so I'm pretty sure that if you rely of moderate to high comp settings, you WILL feel a difference. BUT... I think you'll really dig the Unit67 much more actually. It just have that extra versatility, and that "mid thing" it can do is VERY rewarding to play with. It's absolutely worth buying!Considering this pedal, love the Vibe Machine. For my use into a relatively lower headroom amp (Benson Monarch) - wondering how it'd be w/ soloing I"m trying to hold onto every bit of clean I can out of P90s. I use the Diamond Comp (at 18V) for this, but it doesn't quite have the eq options that wou;d seem nice to dial out some of the mud/mids for soloing. Might this be more compressed and less transparent than the Diamond?, or better at being a swiss army knife eq and throwing in that rangemaster....
