As regular readers probably know, I'm currently on a Robin Trower kick. I've been attempting to learn a number of his songs, and have even purchased a Fulltone Robin Trower Overdrive (RTO) pedal. Since I have modeling amps, I can get close to getting the Trower sound, but running the RTO through a basic, clean model to my ears sounds best.
Doing some research on Trower, I learned that early on he started using a Uni-Vibe. Hendrix also made use of this accident of technology, so I've been looking into Uni-Vibe and Uni-Vibe clones. For those who are more knowledgeable in matters such as this (that means everyone), am I pursuing a dead end? In other words, does the RTO encompass the same effect(s) as a Uni-Vibe?
One pedal that came to my attention was an Earthquaker "The Depths Optical Vibe Machine." The description of it is pretty sexy, but I have no way to compare it to the RTO, which came out in 2008. Obviously, the Uni-Vibe goes back a lot further.
Can anyone shed some light on the pros and cons of adding The Depths to my existing RTO (and filling in the last space in my pedalboard)?
