I'm having feedback issues with my guitar concert setups

Sorry ST

I've mislead you with the info provided.  I get confused with the official name of my L1.  It's the L1 model 1 System

And I use this desk

Then I found your post:

https://www.bosepro.community/...-a-bose-l1-model-one

So my apologies for the run around ST.

It looks as though it needs to be set at 3.

Hi, Perrin Madsen.

Yes, when connecting the T1 to an L1 Classic the input trim should be at 3.

For those reading along, we have an article about this: T1 to L1 Classic/Model I

ST

Thank you TS again for the reply, I really appreciate this, as it's making me feel more confident in my gear for this Saturday.

I have one more curve ball to throw you, I'm having a guest performer who would like to use his own monitors on stage as fold backs...... as he's used to that sound.  He's a professional musician so knows a lot more about this than me.

So he was going basically have his own mix, then feed through the L1 classics to the audience.  I was going to give him channel 4 on the L1 classics and put it through two of them just for a more sparse and full sound.

I have some of my students playing along with him in various combo's.

1. Just himself acoustic plug in with vocal and looper setup (2 songs)

Since no one is playing with him I suspect I'll just mute, turn volumes to zero on any competing instruments, vocals that won't be involved and let him do his thing

 

The  next two songs won't need to be particularly loud

2.  Bass, 3 electrics - He will be acoustic plug in with vocal (1 song)

3. Classical guitar ensemble (unmiked and unplugged), Acoustic PI x3 electric guitarists x 3, again guest performer with his Guitar and vocal (1 song)

 

Does this sound the right way to go about it.  I realise he won't need much through his speakers but if it makes him feel more comfortable, so be it.  He has played through my system years ago..... so I guess it just needs to be more a familiar sound for him.  He's a phenomenal vocalist so I respect what he needs.  

But I just want to appear to be on to it with my bose setup.

PS if you need me to feed this into an existing post, different thread let me know and i'm happy to do so, I just couldn't find this exact kind of question on the forum..... and I'm looking for simple solutions four days out from a big gig for me with a lot of other things to be working on .

Sounds like your worst nightmare  has he worked with Bose L1 systems before*? If you have the main Bose rig up front you'll be fine, just don't feed his stuff to the rear L1. If not, is he a solo singer/acoustic guitarist? Then he doesn't need foldback (unless he uses a looper or tracks (and in the latter case he's just a souped up karaoke singer )). 

Seriously though talk to him and ask for his help he'll probably be brilliant.

* I should add that I don't use L1 systems regularly myself (I usually need a bit more 'rock' volume for my paying punters and my power trio) but, as a musician/sound engineerI understand how they work and for your needs they are excellent.

Just re-read your post, you'll be fine, as I said, ask him and I'm sure he'll be glad to help out on the tech stuff.

I did PA for a high profile UK folk trio "Faustus" a few years ago and my duo were playing as support. Their squeeze box player was Martin Carthy's go to box guy and ex son-in-law, and had just finished a three month run as the storyteller in "Warhorse" on London's West End. He arrived early and sat enjoying his first experience of iPad mixing by happily mixing my duo soundcheck. A total gent

You're welcome.

It may be fine to hook up things, as we'll discuss below. However, have your guest performer listen to the system with the L1s without his monitors. Then he can experience the sound with and without them.  He may be pleasantly surprised.  Also, since he is using a microphone(s?), there will be greater gain-before-feedback as you reduce the number of active powered loudspeakers.



So he was going basically have his own mix, then feed through the L1 classics to the audience.  I was going to give him channel 4 on the L1 classics and put it through two of them just for a more sparse and full sound.

I would connect his signal to just one L1. There's probably no benefit to connecting him to two. It may be counter-productive to have the same signal coming through two as this introduces the risk of Multiple Source Interference and lower gain-before-feedback.

Yes, it's always good to mute microphones that aren't being used.

It's wonderful you're being so mindful in your approach to audio.

We're fine to talk about this here. It's all about the same performance setting.

ST

ok, one bose system, his acoustic is Plug In, Uses shure sm58a so all good there.  Will try without monitors initially, then with and see what he thinks. And..... let him share his knowledge with me.... got it

Thanks for the advice.  It's nice to just head off a few doubts when I'm talking the talk of Bose and how it works best .

Thanks again guys, really appreciate you helping me solve some on going head aches that have been in the back of my mind each concert.  So thank you.

Sorry I have a couple of basic preset questions (last minute unfortuanately):

Could I have some recommendations of presets that are likely to work.  As I have little time for testing a couple of instruments and mics that need some improvement.

These will be plugged into the L1 classic model tower directly so I'm choosing off the 100 settings there:

Boss ME-70 effects pedal with various electric guitars using this

Condensor Mics - Akai C1000s & the Akai LC

And finallly.....Shure Beta 58A - Hand held PGX2 - This one is going into the T1 Tone Match and if I remember rightly I read on the forum that hand held mic was better setting than the Shure SM58A setting..... any thoughts.

Sorry I'm not in a position to test all settings at this stage, so a few glues will be more than enough help

 

And on the off chance someone might know a good setting for a Peavy PVi100 mic.  I may not use it, but it may be needed in case of a mic failure.... so better to be prepared with a half decent sound right off the bat.  This would be plugged in to either the T! Tonematch or the Bose L1 classic.

Any help appreciated, the simpler the better at this stage

 

Hi, Perrin Madsen.

There's no substitute for testing, but I'll do my best to make some suggestions. Please note: There were updates to the Presets for the L1 Classic in December 2004 (version 2.0) and November 2007 (version 3.0).

We can't know if you have the updated versions. If you use a Preset 39 (mentioned below) and it is not installed in your L1 Classics, the result will be the same as using Preset 00 (no Preset).

At this point, I would not attempt to update your L1 Classic systems.

The Boss ME-70 has guitar amplifier and speaker modeling built-in.  Use Preset 00. This is "Flat" and the will rely on the Boss ME-70 to create the tone for the electric guitars.



Condensor Mics - Akai C1000s & the Akai LC

You are using these on your classical guitars so use Preset 39 and compare that to Preset 41. Use whichever sounds best.

There is a Preset in the T1 for the Shure Beta 58A. Use that for the Shure Beta 58A/PGX2

Category: Vocal Mics
Preset: Shure Beta 58A

If you're using the Peavy PVi 100 for classical guitar:

  • If you connect to the T1
    Category: Acoustic Guitar
    Preset: Nylon w/Dyn
  • If you connect to the L1 Classic
    Preset 39 and compare that to Preset 41. Use whichever sounds best.

If you are using the Peavy PVi 100 for vocals



  • If you connect to the T1
    Category: Vocal Mics
    Preset: Handheld Mics
  • If you connect to the L1 Classic
    Preset 01




Any help appreciated, the simpler the better at this stage

Have a great concert.

ST

Thank you
