Always nice to see another up-and-coming builder on TB!
At the bare minimum, we tend to look for:
- little to no low end loss (the no-brainer requirement for most of us
) - wet/dry blending is a plus with many effects... but so is a level knob to compensate for volume drops when blending!
- if it's fuzz, clarity is a plus!
Everything else is pretty much like what I'd expect from a similar guitar effect.
We all have varying expectations though - what's listed above is based on personal observations on TB and personal experiences.
I personally like my stuff small, simple but flexible, and dedicated to a single kind of effect (maybe two... maybe).
Others will have different expectations, though!
