"List your top 3 unused effects..."
Or...I wish I had an effect that I don't have...
After an extensive experience with pedals from the Mu-Tron III that I bought (and not a reissue) that I couldn't tell you where it went or whatever happened to it. To the last eight years of many pedals over time and at one time, at times. Here is where I have landed and have the final pedal OTW...
The two preamps have simple unique functions from a HPF to the bi-amp clean/dirt XLR's with good cab sims and a blended 1/4" output to the HX One with a small midi controller. With or without an amp.
The last pedal is a VerTex Boost MKII with a buffered TRS insert (for running the mod/delay/reverb) into the amp effects loop and a truly transparent boost.
I never use more than one (1) effect at a time. The HX One offers enormous flexibility in access to VERY good sounding effects, is SIMPLE to operate and has other utilities like a noise gate and tuner.
At this point in the journey is where I step off the carousel of pedal dreams. The music that I like to get involved with has the space for textures, dynamic content and layers and solid clean and dirty Bass tone.
The electric Bass, processed well, sounds better than any Bass/Cable/Amp rig out there, but it can be done.
