VT Bass and BDDI feature a clean blend; this has a touch of gain and EQ applied to the clean side, AKA the deep channel. Should sound fatter overall and make the two channels more cohesive.
The VT and BDDI flub out with too much low end hitting the clipping circuit at high gain. The YYZ has a switch to cut the lows entering the dirt section.
The BDDI has a mid scoop that you need to fight against with the EQ. The YYZ has a very present midrange, I'm interested in seeing how it compares to cranking up the character on the VT.
I love the DuG pedal but it's best in a supportive role, humongous chasm in the mids creates space for heavy guitars yet still cuts and punches through. I would like something with more midrange poke for when the bass is taking on more of a lead role.
Early reports from users experienced with all their previous pedals have said this is the best thing they've ever put out.
That's why I want to try one. I've no interest in trying to sound like Geddy Lee, I've not listened to much Rush - I gave it a try once and had to switch it off!
