Tube Compressor

At first, I thought this pedal didn’t do too much. After a while of tweaking the knobs, it all became so much clearer. You can add a little bit of grit if you choose, or a little bit of boost, or a bit of both. It adds a little sustain and fullness to the sound. A little goes a long way. The only gripe is the dodgy power lead that feels like it’s going to fall out any second and is not one for easy replacement. I like it though. I generally have it on all the time. Good pedal.

Not The Best Compressor By Any Means

I've kept this compressor around to offer options to players that want to use my gear to record with. I personally do not think this is a good compressor. It's noisy, big, clunky, has a special power adapter/jack, and doesn't seem to... compress. Again, it is worth keeping in the collection if you want to use it for something really experimental, like the "squash" feature to kill the bandwidth of your signal prior to running it into some wacky modulated effect. Otherwise it's just not the same as a quality compressor with the research and craftsmanship behind it like a Walrus Audio Deep 6 V3 compressor.

So nice smooth sounds are with acoustic guitars and warm & hot compressed sounds when attack is set up higher

You can use it with acoustic or electric guitars and even basses, you choose your mode Led or Valves compression, the sounds are different and attack also, but when your bout it in the effects loop it becomes very efficient with overdrive and distortion even at low level, sounds become very aggressive especially with Blackstar HT-Dual (Valve) and Blackstar HT-DistX (Valve). I bought it on Ebay because mine was stolen in my car ..... you can change the valves 12AX7 with ECC83 ECC84 JJNxxxxx a lot of if compatible. I finally mix one 12AX7 and one JJxxxxx
