KORG PB05 Pitchblack Pro 1U Rackmount Guitar and Bass Tuner

I needed a new rack tuner and this was about the only reasonably priced unit on the market. Nice looking but as other reviews is not at all sturdy, if it was to be situated outside a rack I would have returned it. It is all plastic with wobbly push on rack ears and unfortunately comes with a mains adaptor rather than a mains socket/kettle lead. Once in the rack there is movement as the ears float a little where they clip on the ends. The tuning readout is world class and probably the best I have used, easy to see and easy to tune to pitch. It has great non-concert pitch tuning - I play both tuned down a tone and at concert and it auto detects wonderfully. It appears reliable looks good and apart from the mains adaptor, wobbly ears and plastic non-metal build seems ok. I paid £85 and if they sorted the ears/plug would say it was value for money if situated in a rack environment.

This is quick, easy to use and accurate. Doesn't take up loads of space. If you either build/repair guitars, or perform seriously on stage then this is highly recommended.

Perfect what more can I say !

Great tuner easy to see and tune .Can use stand alone or inline with other pedals from Guitar 🎸 to amplifier .Beat looking at little fiddly gauge no struggling looking over to see what's going on .Very accurate tuning and looks and performs great.

The positives of this unit are that it is easy to use, has an excellent & clear display, and gives a more stable tuning indication than you get with tuner pedals, which I fine can wobble around the indicated pitch quite a lot.Downsides, it’s a bit cheap & plastic-y, particularly the plastic brackets/ears for rack mounting it. It’s not an issue for me, as this is for home use, but you wouldn’t trust this for gigging from a durability/road-worthiness point of view. As such, I don’t think it represents particularly good value for money, but overall it does a good job and I’m happy with it.

Incredible piece of kit. Blue LED’s light up on the left and right sides when you power it on giving it a really futuristic look. The unit is made of good solid plastic and feels like quality. Very very accurate tuner. Mode one is the middle LED - nice and simple. Mode 2 is the strobe which, I feel, is the most accurate of the tuning displays and you could spend hours tuning your instrument. Mode 3 is a mix of single LED and strobe mode. The LEDs are ‘3D’ which can be noticed if you look at them from either side. Very bright and extremely easy to see. I have it connected at the back to my Line 6 POD Pro HD Multi-FX so you only need to plug your cable into the front input of the tuner; the output at the back can go right into whatever input you desire. Amazing.

It's a lightweight unit for sure being made from plastic rather than metal, but I was aware of that before purchase and came as no surprise. I shall install it within a pedal board anyway so in a way its lightness is a bonus.With three different display settings I will have to see which works out best on stage, I suspect static strobe for me.Tracking seems pretty good and stable no better than comparable pedal tuners but again the internals are likely to be very similar, it's just that you get a nice big display with the rack unit.It won't be going back so I'll try and update at some point if there are any niggles.

I find this much easier to use than the boss pedal, it's accurate and made tuning faster and more precise. The cable tester is a brilliant feature and already come in handy when trouble shooting. Love that there is an input on the rear and an output to pass signal through to other units. Brilliant!
