Help! My Bose Tonematch L1 Model 2 all of a sudden sounds tinny, has no body of dynamic range!

Hello everyone, I have been searching through posts trying to find answers but can't.  I have been a big fan of my L1 for over 2 years playing many gigs with it and was extremely satisfied and always complimented on my sound.  After a year of small tweaks depending on the venue I was so happy with the fullness and dynamic range I was able to dial in and in a few days it has disappeared and I can't get it back. 

Acoustic guitar player with Taylor 5 series Koa and Fishman Matrix Piezo pickup.  

Tc Electronics Voice Live 3 Extreme

Sennheiser mic

I run vocals and guitar through Tc Helicon and into channels 1 and 2 on tonematch. Then I run a quarter-inch into channel 3 with backing tracks. 

I have changed all chords, muted all effects, run direct to tonematch without TC electronics. Trim on base always set at the position 5, base switch to neutral. Yes, I have used all of the different presets to see if I could find the sound again.  

So here is what happened. It all started with the system getting pretty damp when it rained in on us at a gig.  The system was fine for a few months after that but now it has changed. In addition, my guitar got damp and apparently water seeped into the bridge and malfunctioned the piezo so I had a new one put in (Exactly the same one). So after I got my new pickup in the guitar I plug it in and all of a sudden the entire system including vocals and backing tracks sounds awful. I hadn't changed any settings so then I started trying to tweak everything seeing if maybe it was just my new pickup. It wasn't as I could get my sound back through another system. Also, a potential variable that could have affected the system was a couple of weeks ago as I was trying to find the sound again I accidentally left my L1 on for over 24 hours sitting on my carpet at home but did have clearance underneath to vent.  

Once I got the guitar back with the new pickup I plugged it in and it sounded very tinny even going back to my original settings and scenes. The vocals and backing tracks have the same problem. All channels seem very compressed. Everything has no body, just frequencies that hurt your ears. Yes, I have tried the Para EQ but the problem is so significant it isn't a matter of just dialing out a frequency. There is another problem somewhere. When I try to dial in more base it just gets muddy and doesn't fix the problem. 

So I here is what I have determined.  I have run my tonematch out to other speakers and I have the same problem so it isn't the speakers themselves. Then, last night I used a buddies bose system with his tonematch and my sound came back after loading my settings but it was on his system which tells me my problem is most likely in my tonematch. 

Last night we had a little epiphany, when we plugged the backing tracks into his tonematch 4/5 we had a very compressed sound with no range. This is what all channels sound like on my tonematch. It's the same kind of signal.  When we switched the backing tracks to another channel it sounded great.  I have never understood why channel 4/5 always do this. It happened on my tonematch as well but I never needed it so I never looked into it. Whatever is happening with channel 4/5 with that awful mono/midi/tinny type of sound in that channel seems to be on all of my channels now. 

Sorry for the long post but I have no idea what to do and I have gigs. I tried to list everything I have done here to find the problem and what my thoughts are.  Any help would be greatly appreciated. 

Hi Corey,

Welcome to the forum. Sorry it has to be on a bad note.

You've covered a lot of territory here and there are many possibilities for your problem so we need to try and isolate the components.

You seem to have determined your ToneMatch mixer exhibits the same problems with other speakers.

So, ..................

I would contact the friend and have him connect his ToneMatch mixer to your Model II.

Leaving the Model II on and unused will not harm, or over heat the system.

If his ToneMatch works correctly with your Model II, then I would do a factory reset to your ToneMatch mixer to see if that helps. 

In order for us to be of any real help you need to narrow the possibilities one at a time.

O..

Should he also update his firmware if needed?

Hi, Corey,

Let me address this part.

Backing tracks. Are you using a cable like this?



If you connect a stereo signal with a 1/4 inch (6.3 mm) Tip-Ring-Sleeve jack to T1 channels 1, 2, or 3 - you will hear only the Left side of the stereo signal. The 1/4 inch inputs on channels 1, 2, 3 are unbalanced mono.

If you connect a stereo signal with a 1/4 inch (6.3 mm) Tip-Ring-Sleeve jack to T1 inputs 4 OR 5, the Left and Right sides will be combined with the polarity reversed because inputs 4 and 5 are balanced - they are NOT suitable for a stereo signal.

We have detailed notes about connecting backing tracks to the T1 in this article

There haven't been any recent firmware updates to the T1  - nothing in the past two years.

The firmware updates for the T1 in the past did not change the sound.

Corey, what version level is your T1 ToneMatch® Audio Engine? (T1® for short)

  1. Turn the Rotary Selector to Prefs


  2. Press the first button


  3. Turn the first button until you see Versions
  4. Press the button


  5. The versions for the firmware will be displayed. The versions shown below are sample values.
    See:T1 ToneMatch® Audio Engine Firmware Updates for the latest firmware


  6. See:T1 ToneMatch® Audio Engine Firmware Updates for the latest firmware



Right now the latest T1® firmware is 1.8.

What have you got?

Notes: What version of the T1® Firmware do I have?

Good morning oldghm, thank you for your input. Couldn't reply until today as I hadn't had time to go through these suggestions. So I did get my friends tonematch and hooked it up to my base and tower. Unfortunately, the problem still exists. Still having uncontrollable high mids (kazoo/tiny sound) almost like not hearing one side of a stereo sound but I know that it is mono however it never sounded like that. When we hooked up to his system entirely the problems went away and we had a full dynamic range and he has the smaller system.

Good morning ST, thank you for your input. So your correct and now I understand. Yes, that is the cable I was using for 4/5 input. Thanks for explaining.

Yes, I had already done this but did it again and still no beuno. Still can't dial in a good full sound. Yes, the firmware is up to date. 1.8

Thanks mojo, frimware is 1.8, presets 1.1, scenes 1.0. So I have tried everything I know and all of these suggestions. It's really puzzling.  I all of a sudden just have this very bright tiny sound from all channels even when I use someone else tonematch on my speakers or when I use my tonematch on their speakers but when I use someone elses system and hook up my voiclive, my mic, my guitar, my chords, and my backing tracks my sound comes back close to where it was before. I know, it's very strange. It's like the problem is in both the tonematch and the speakers separately. 

I am still having to play with the system and several people have said the same thing to me that it sounds very "bright" and I think they are trying to be kind lol. 

I can't thank everyone enough for your ideas and input. I have spent over 20 hours checking and changing chords and settings trying to see if I am just missing something but even my buddy who has been using a bose system for some time hears it as well and can't dial it in either.  I have hooked up other guitars, other mics, other backing track sources to see if that helps and they all have that same non-dynamic kazoo sound that you can't get rid of no matter what affects you use or not use. 

I have no idea what to try next accept find a certified tech who works on these systems and have them check it somehow.
