This is my first real pedal review on here. I posted in an SP compressor thread last night with a short review of the SP. I only played it for an hour, at bedroom volumes, and initially I wasn't impressed and didn't like what it was doing to my low end. But, I got home from work today and was finally able to turn my amp up a bit. I played my tele w/nocaster pickups into a NOS Blues Jr. with JJ tubes. This is a really good compressor. I figured my disappointment was due to lower volumes, so I'm glad I was able to turn it up. I just want to highlight a few features/perks that I particularly enjoy about this pedal. For reference, I have owned a Barber Tone Press, Keeley 4-knob, and the MXR Custom Comp (which the SP is now replacing). 1. The blend knob is really tastefully integrated into the pedal. I like it more on this pedal than I did on my Barber. It feels like it actually "blends" the clean in instead of having that odd experience of having clean tone replace compression signal. 2. The dip switches and the compression switch really make this pedal versatile. I haven't owned a Diamond, but I have played a friend's and I was able to replicate Diamond-like compressor tones with the switches set to stock, high clean blend, and the compression switch on low. But, after just switching to the mid/high compression setting, and tweaking the attack dip switch, I was able to get very squashed Keeley compression, but without losing the high end. Which brings me to my next point. 3. What this compressor did for my high-end is magical. It has a very EP-Booster mojo to it in the sense that it just seems to sweeten everything. Since I typically leave my compressor on full time, I really like that the pedal does this to my top end. It gives it that sparkle/chime that I love so much. 4. The SP has some serious boost on tap. 10 o'clock is about unity and it gets loud quickly. I appreciate this amount of oomph because I like to boost my signal slightly with my compressor, and the SP only seems to get sweeter the louder it is set. It never distorted or got gritty even at high volumes. 5. This should go without saying, but this pedal is extremely well built. It is just as tough as the EP booster and looks just as good. I love the space it saves on my board and the green LED is a nice touch. Overall, I think this pedal is a winner. I certainly like it a lot more than the Keeley and the Custom Comp. And I give it an edge over the Barber. Once again, I can't directly compare it to the Diamond so I won't comment on its comparison. With the clean blend, I was able to preserve my dynamics and pick attack, but with everything I love about a compressor. It made my chords and notes ring for days without feeling false, like my tele was actually sustaining that long on its own. Hopefully this review will help anyone who is on the fence or just genuinely curious. As we all know, this is just my experience with my rig. Hope some more people chime in with their experiences as more of these get shipped.
