Keeley Compressor Plus....WOW!

Gerry Lane, 07.08.2017
I bought this compressor just last week from Thomann and, I used it for the first-time last night at my regular 3-hour gig/4 nights a week here in GC. All I can say to describe it is ?WOW?. I really like the design of the 4-knob compressor (Keeley also have another 2-knob model which I haven?t tried). I've been using another brand name micro compressor for the past year or so and, it?s also good but, this Compressor Plus gives me a lot more control?. over everything! It also has a little toggle switch that changes from single coil to humbucker (that changes the attack and release depending on the guitar you use) but, I have only used it so far on my Strat and it makes the guitar sound great, bright, clean, full, and it doesn?t introduce any noise whatsoever into the signal path. Adjusting the tone knob (bringing it back to about 11 o clock) backs off the treble just enough on the single coil Strat so that it isn?t ?head-cutting? just, a nice bright full and warm sound. The build of the pedal is VERY strong and sturdy?it looks like it could take a lot of punishment!!
I really like this Compressor Plus. It?s my first Keeley pedal and, having seen the great quality of this particular pedal?I am certainly going to check out the rest of their stuff.
Thank you, Keeley, for a really great product and, thank you Thomann for the great service... (this package arrived at my door here in Gran Canaria just 5 days after ordering it) SUPER.

Magic box

NicoAlfredo, 19.02.2019
I bought this just over a year ago and I couldn't be happier. I play small and medium gigs/sessions in different settings (jazz, Latin music, hiphop, pop/rock). Versatile and useful.

Most often I keep the "sustain" knob between 09:00 (subtle) and 12:00. The "blend" makes it easy to dial in more or less effect when needed.

Especially over 12:00 on the sustain, both the blend and sustain knobs have an effect on the overall output. Once you get used to this and learn to adjust the "volume" knob accordingly.

Note: When people say this is a "warm" compressor, it's true: Like other analog units, at high sustain/blend settings the sounds gets a pleasing halo of creamy harmonic distortion. Overall this doesn't bother me (I mainly use it at lower settings).
If you are specifically looking for crystal clear, transparent output at high compression settings, this is not the box for you.

For most other uses, I enthusiastically recommend it. At this point this magic box has been so useful that it's become part of my sound. Well done, Keeley!
