The key input is key. Pun intended but no jokes here. You key it off your guitar directly in and there is a key through so you can go to the front of your amp from there. Put the Zuul in the loop and wallah. Your amp suddenly sounds like a record being mixed on an SSL console.
Brings all of my amps to life. Eq your amp with the pedal on and add your low end back in.
The spliff delivers exactly what it promises: 3 strong buffered signals. This is a great tool for any guitarist who want to run dual Modelers along with being able to still send a signal to a traditional amp. Just put it after your drive pedals and get an awesome source signal to multiple amps/models.
The 33 pedal brought my VHT to life and added clarity that I didn't even know that I was missing!!
