Dudgeman Posted June 2, 2019 Share Posted June 2, 2019 I use a dual amp set up and despite many years using OD , distortion and fuzzes I have never had issues with feedback. At home I run my pedals into logic and never have issues no matter how loud but in rehearsal rooms I struggle to quell feedback when using Sheehan drive deluxe pedal. I do set the dirty amp up with a slight mid hump ( I need to to bring out the harmonics like Billy does) but I do that in logic as well...I have tried reducing amp gain and lifting amp volume, reducing amp volume and increasing level out from pedal, massively reducing level out from pedal and increasing master volume on the amp so I can mix it with the clean amp..but am still struggling... it's ok as long as I face away from the amps but it is still hovering... I think I am being dumb somewhere here so any advice on the correct approach would be great Thanks Quote Link to comment Share on other sites More sharing options...
NikNik Posted June 3, 2019 Share Posted June 3, 2019 Could be the pickups? Quote Link to comment Share on other sites More sharing options...
cheddatom Posted June 3, 2019 Share Posted June 3, 2019 too much gain on the pedal? Or yeh maybe your pickups are going, are they microphonic at all? Quote Link to comment Share on other sites More sharing options...

The gain on the pedal is around 12 o'clock...which is about where it needs to be with my set up to get the sound I am after... if i drop the mid hump in the EQ it reduces it but then I lose all the articulation and it starts to get wolly sounding. It was a lot better this last rehearsal and will be fine on a bigger stage where I can get away from the amps but in a small rehearsal room it is an issue...bizarre it doesn't happen at home at all. Thanks for your help so far. Quote Link to comment Share on other sites More sharing options...
cheddatom Posted June 3, 2019 Share Posted June 3, 2019 Surely you're playing a lot quieter at home? Which would obviously reduce feedback 1 Quote Link to comment Share on other sites More sharing options...
Dudgeman Posted June 3, 2019 Author Share Posted June 3, 2019 Yes but not by much...lol... just wondered if there was a known issue with this pedal live or a simple way round it..... Quote Link to comment Share on other sites More sharing options...
fretmeister Posted June 3, 2019 Share Posted June 3, 2019 More gain in the house, less gain in stage. Same with all driven tones. Quote Link to comment Share on other sites More sharing options...
2elliot Posted June 3, 2019 Share Posted June 3, 2019 Turn the gain down. Quote Link to comment Share on other sites More sharing options...
cheddatom Posted June 4, 2019 Share Posted June 4, 2019 It sounds like at home you have a studio monitor type setup? Which will be very different from running into your two amp setup. You could try "ringing it out" with a parametric EQ but to be honest it sounds like there's just too much gain and/or volume. What does the feedback sound like? I quite like a bit of feedback but you do have to get used to controlling it. If it's a horrible squeal when you want silence then you could use a gate Quote Link to comment Share on other sites More sharing options...
MoonBassAlpha Posted June 4, 2019 Share Posted June 4, 2019 what's the cab setup at rehearsal? Is it higher off the ground so it's exciting the body of the bass more? I found a notch filter as used on acoustic guitar preamps killed the feedback on my mate's problematic Hofner Verithin Bass without affecting the overall tone.

If it's a horrible squeal when you want silence then you could use a gate Hi at home I use logic pro with yamaha Hs7s well cranked as I also have one channel octaved up distorted running into a Peavey 20w valve amp to replicate guitar and that runs fairly hot...essentially very different from rehearsal ... feedback is very high pitched ..bloody annoying. The gain thing is wierd. I have the drive at around 12 on the pedal..if I drop the drive below 12 I lose all the sound I am after... I can get shot of the feedback by slamming the input gain down on the amp but then I struggle when the pedal is off to get the required volume out of that channel. I 've seen Billy running something very similar where he is stood riggt in front of the amps with the pedal dimed, hitting ridiculous levels of harmonics with a major mid hump eq with not even a flicker of it feeding back. on both Rigs ( trace and hartke) at the practise room the cabs are stacked...maybe I should park them side by side...see if that helps..

cheddatom Posted June 4, 2019 Share Posted June 4, 2019 Input gain turned down on the amp sorts it, so can't you adjust the output of the pedal to try and match the level with it off? Quote Link to comment Share on other sites More sharing options...

It seems with the trace rig I was using that if I pull down the input gain to a point where the feedback isn't an issue I had to basically run the amp flat out to get any volume to match the level of the 2nd amp and even then it was struggling...not enough headroom I guess ( not sure what the power output is) I will try that using my Marshalls as they are wahay louder...then I might be able to balance it. I am thinking about dropping the drive on the pedal and running a second drive in the clean loop on the pedal to try and get the sound that way...
