Ive been going to buy either a Neunaber Immerse MK2 or a Quaverato Harmonic Tremolo Pedal by Zeppelin Design Labs for awhile now. A good deal on a guitar would come up and I would have to put the expensive pedal purchase off multiple times. I came upon this and and convinced myself it was a 2 for 1. Since its a Keeley I knew it was going to sound great. I was correct in that assumption. The steel drum option also helped sell it for me. Ive had an original song Ive been working on for 20 years that has a Marley/Cliff/Tennors feel to it and have never come up with a good lead fill for it. I think the steel drum sound will do it. I'm close already. Keeley Verb-o-Trem Workstation 6 Reverb types 1 Slapback echo 1 Octave trick that sounds like steel drums. 5 Tremolos 1 Pitch Vibrato 1 Rotary 1 Uni Vibe I'll need to buy an expression pedal that will allow me to control the rate of reverb decay. 4 controls for each of the 16 different effects. The 6 reverbs are all you would expect from a Keeley product. There is no Wet Reverb or Shimmer option like the Neunaber. The Harmonic tremolo is inferior to the Quaverato IMO. Ive never heard a harmonic tremolo that matches the Quaverato's unique tone. There is so much going on option wise with this pedal it will be a while before I get a good feel for it. Here is how Im set up with it currently. The $20 Mosky OD (Klon Centar clone) is real sweet. If you have any questions dont be shy. I will try my best to answer.
