The VFE pedals are interesting. I agree they can sound clinical... I owned 4 Standouts and the first one I got is the only one I have left. It just had a little more magic and to me didn’t sound clinical. The two Dragons sounded great, but both sounded too clinical for me...they just were missing a little character. Kind of like the difference between the JRC4550 and TL072 op amps. Like you said, the Merman never had that clinical sound...but it’s a Klon clone so the design is quite different.
I love my TC1140 PEQ, but it’s not always easy to swap out for different sounds... pedals make doing that super easy. ?
