Back at band practice/rehearsal last Friday night, refining set lists for an upcoming gig next Saturday, my first with this band. I was using a Front 'n Center custom wood mic through a digital delay and Harp Attack and then straight into the PA, as I've been doing for the past few weeks with no problems. I start getting feedback from the mic at about 50% volume, and even though I move about the room, it doesn't go away. I pull out a Shaker MadDog mic...no feedback but not enough volume. I have an Ultimate 58, but I didn't want to fish around for the IMT, so I grabbed the Bottle 'O Blues, which I keep in my case mainly as a conversation piece, and plug it in. No feedback and pretty decent sound. It cost me, I think, $50 a few years back. It was my first harp mic, and I used to use it through a little Pignose, which is friendly to most any mic. So hoodathunkit? A marginal and almost forgotten piece of gear comes through in the clutch.

From reading your post sounds like you're set up like this Mic- Delay - Harp Attack - PA is that correct? If so you might want to set it up so that it's Mic - Harp Attack - Delay - PA. That will give you a much better sound and will most likely make feedback much less of a problem.

If that's what you're already doing then please just ignore my ramblings.

Yes, Kingley, you're correct, it's mic, delay, Harp Attack and PA. I'll try that. I assumed it was the mic, but this morning I tried it out on an amp, and it was fine. I also tried the Bottle 'O Blues in comparison, and they both fed back at about the same amp volume, maybe 85-90% with the mics cranked all the way up. Thanks for the advice. By the way, should the delay always or most always be last in line, say with an Octave pedal, for instance?

Personally I would always put delay last if using a few pedals. The only time I wouldn't is if I was using a BBE Sonic Stomp. Then the Sonic Stomp would be last in the chain. If I was using an octave pedal then I'd put the delay after it and not before it. A couple of things to bear in mind are that if you're running it on battery power then low batteries could cause it to oscillate erratically and that could create feedback problems, so change the batteries regularly. Better still run it with a power supply. Also the higher the pedal settings the more likely it is to feedback earlier.

I'd try running the mics on full volume, set the delay short and if necessary keep the blend/mix to the amp at around 12 o'clock. See if that improves things. If you're using more than one pedal then I'd switch them all off and test the amp by turning on one at a time in sequence to see if you can isolate the offending pedal.

With the Harp Attack I never set my volume on it past 1 o'clock I usually run it around 11-12 o'clock. I don't know if that will help with feedback but it's worth trying out if you currently set yours higher. I also keep the drive and tone both at 9 o'clock.

Okay. I have the volume at 2:00, drive at 9:00 and tone at 12:00. I run a power source and not batteries. Looking back, the first thing I SHOULD have done is turn off the pedals. I will bring an amp to the gig Saturday. It's an outdoor venue, so I can crank it some and run sans pedals. Thanks again.

Those settings shouldn't really be giving you any problems in the PA.

When using an amp do you use the Harp Attack with the amp to give you extra overdrive?
If so what amp are you running and what settings on the amp?
Or do you always use the Harp Attack just directly into the PA?
If you've used it before and had no issues, is it possible that someone messed with your PA settings?


I've used a Harp Attack direct into the PA with a very loud band and had no feedback issues at all.

I've never used the Harp Attack with an amp, only into this particular PA and at this particular location. I know my volume was adjusted at the PA, so I can imagine settings could have been inadvertently changed. But I had no problem when I switched to the BOB and then no problem with the bullet mic through an amp today. Outside of practice, I use a Fender Bassman with delay. If it's a smaller venue and I can't crank it some, I'll use the Octave pedal, too.
