    I play jazz guitar. One of my favorie guitars is a Gibson ES175 with one P90 single coil pickup. Love the tone but hate the 60HZ hum. I do not use any pedals and go for a really clean tone. I tried the ISP Decimator and the Boss NS-2 to rid the hum but being that they are noise gates they don't work well on pedal free guitar tone. They are more for getting rid of noisy pedal hum. The EH Hum Debugger works perfect. My P90 is now quiet as a church mouse with no effect on natural tone or sustain. I love it. My only complaint is it is made out of cheap looking steel and for the price you pay for it they could have put a nice coat of paint on it. It is a bit of a eye sore but it works fantastic. If you want clean and quiet single coil tone buy one !!!

    Well it works. I tried it on a Rhodes piano, Clavinet, and guitar. It was remarkable on the Clavinet. It got rid of the nasty hum. Only one problem, I noticed one note in the higher range of the keyboard was very faint. Did the same thing with the Rhodes and it was the same note. Upon closely comparing the effect to bypass signal, there is a nasal quality to the sound over all. At certain higher notes there is almost a canceling effect. It does work, but for me I can't take the side effects. The tone is almost missing something when this pedal is on. When its bypassed, the signal becomes so much fuller and true. Some people may not notice, or care. For me, its not worth the trade off. Still Electro Harmonix did produce a very unique pedal. For certain situations it would be welcomed to get rid of the bloody hum. There is nothing out there that does what this pedal does.

      Comments about Electro-Harmonix XO Hum Debugger Hum Eliminator Guitar Effects Pedal:

      Works as advertised. My Les Paul Jr. is one of my favorite guitars, but I've always found the hum distracting in live situations. In a fit, I added a debugger to my pedalboard, and was able to play my Junior all night at a recent gig.
      This is a great and effective product for eliminating single coil pickup hum.

          Works fine. On the strong setting it seems to affect the tone somewhat. I only use on normal
          because it's all thats needed in my case. Does
          seem to add a weird fuzzy noise to the signal
          but it's very faint and can't be heard while
          playing.

                    I bought this product as a last ditch effort to tame the noise on my carvin v3m's distortion set with a high drive. With one kick of the pedal... Perfect silence. I was amazed. I read other people's reviews talking about color added to the sound... But I was please that there was no noticeable difference. This is a must have for every guitarist. The only negative with this pedal is that it must be powered by its own power supply. So instead of plugging it into my voodoo labs pedal power supply, it has to be run separately. I'd rate this as a 9.5 out of 10... And if they could get this to work off a 9v... A perfect 10!

                    Solved my 60 cycle hum problem

                    Comments about Electro-Harmonix XO Hum Debugger Hum Eliminator Guitar Effects Pedal:

                    The Electro Harmonix Hum Debugger pedal is essential to your rig if you have single coil pickups and want to remove 60 cycle hum from your tone. With my simple setup I haven't noticed any loss of tone quality. Now I have the best of both worlds, vintatge Strat pickups with no noise. This pedal really works.
                    I recently switched out my noiseless pickups on my Strat for some Texas Specials which are very hot and produce alot of the typical 60 cycle hum found in all single coil pickups. I play in a church that has old wiring and computer/projectors nearby and the hum became very noticeable. I bought the Hum Debugger plugged it in and no hum! This pedal is amazing. Some folks have said that it colors your sound slightly but I haven't noticed any difference and I am a tone fiend. My rig is simple, just a tube screamer and a delay pedal. As for features, its either on or off. There is a strong setting but I found it wasn't necessary to use.
                    Seems to be well built and solid. EH has a good reputation for high quality products.
                    $120 might seem pricey but having no 60 cycle hum is well worth the cost.

                    .
                    I've tried for years to remove single coil hum. Attenuators, shielding, new pickups, you name it. Sometimes it's been so bad that even humbuckers hummed!

                    This device fixed it first time. Easy to use, easy to hear.

                    Penalties? A slight nasal effect to the tone, but hey...that's a lot better than hum and can be generally fixed by tweaking a tone control.

                    If you have hum from your guitar....get this box.

                    Got rid of virtually all of the buzz/hum from my strat. Now I can use any pickup configuration. Heavy duty metal construction.

                    too much colour for me

                    Comments about Electro-Harmonix XO Hum Debugger Hum Eliminator Guitar Effects Pedal:

                    It does what it claims, LOWERS the hum/buzz/hiss level, but with way too much colouration.

                    I play all single coils (2 G&L's with standard Strat/Tele style pu's and a Hamer Vanguard with P90's) thru an early US made Fender Pro Jr and a gorgeous Reeves Custom 10HG with Weber loaded 1x12 cab. The buzz and 60cycle hum I endure on a daily basis would make most modern guitarists cringe.
                    While the Hum Debugger lifted the noise considerably it also ruined the sound of these Class A tube amps. The Fender became unbearably shrill and the Reeves sounded like it was inside of a damp aluminum can. Very odd and hard to describe the tinny-ness of the resulting tone.
                    Perhaps if you use massive chains of stomp-boxes and you're noise issue is of a different nature than mine this may be the solution for you. Not for me. I'm not much of an FX fan. Tone is in your fingers and your gear.
                    not many. on off, normal-strong lift...
                    seems good
                    a bit pricey
