Well thought I had my problem solved with the new Mullen Discovery single coil but it appears that I don't. I have some objectionable hum that I can dial out with the noise gate on my Kemper, but it comes back when I play any string and goes away as the sound fades. I have changed cables, outlets, tried it at venue I play at and it was worse there than at home. No dimmers in the house, unplugged all florescent lights. I tried the turn up the amp suggestion but that didn't help. Just made the hum louder. The hum does not go away when I touch the strings, changer, or legs. Down to two choices I am thinking swap out the single coil stock Mullen pickup, or try one of the hum debugger pedals. Thoughts???? I appreciate any help.

I haven't tried that EHX pedal (and there's a bunch similar products see reviews below) but the only thing that made the hum tolerable in my strat was pickups w/dummy coils, whereas my steels with single coils like Mullen and Truetone are reasonably quiet (and those are my favorite pickups vs Geo L, alumitone).

Your PC is likely throwing off 1khz noise as well wheen you're tracking. Here's previous threads about other sources of interference, diagnostic tests etc

Thanks for the advice and the links......I tried tonight to dial in just a small amount of noise gate on my Kemper and got the hum down to a reasonable amount without affecting the tone to much. I think the permanent fix might be replacing the single coil with another pickup.....read good reviews of the 705...one in a Discovery...so perhaps I bite the bullet and replace the stock pickup.

The Hum Debugger can work miracles with that kind of situation with very minimal impact on tone. It's a completely different animal from the usual noise gates/hum cancellers that I've tried.

I had a Mullen Royal Precision SD12 that had the original single coil Mullen pickup. A couple of venues I played at, the hum was almost painful. I will say that I think Mullen's pickup is a great sounding pickup. But, in some places, a single coil just doesn't cut it. In these venues, the guitar player (Tele with single coils) and bass (also with single coils) had similar problems. I ended up installing a Bill Lawrence XR16, with a coil tap switch. I could switch from single coil to humbucker if hum was an issue. Sadly, I had to sell that Mullen to help with my move recently to Montana from California.

You might want to try a pickup with single coil/humbucker capabilities. I believe some 705's have split coil ability. I have seen both 2 wire and 3 or 4 wire versions.

This is another argument in favor of switchable pickup systems like the new MSA and older (and I think maybe the newer) Sierra guitars. Got hum? Put in the humbucker. No hum? A single coil it is.

Well bit the bullet and got a 705 from Mike at Mullens and installed it yesterday.....sounds great in my Discovery and whisper quiet even when I put volume at max. No hum. Installation took about 45 minutes, but was super easy.

I saw where Robert Randolph has a HB and a single coil back to back in his Fessendens, I was wondering if that hurts sustain/tone/anything else to have that big a cutout in the neck for 2 pickups
