    I follow the instructions of the tenoprint application, I put my iphone next to my bass pickup volume at 10 and nothing happens on the amp, impossible to change the effect already loaded on the amp. The firmware is up to date, i don't know what to do...

    Thanks for your help

      NicJonesMT Hi cgu93.
      Please select Library and then click the 2 cogs to open the settings. Change the Library setting to "Browse by Product" then close this menu. In the Library you should then see the TonePrint Bass Amps option. Can you please try beaming one of the TonePrints found in TonePrint Bass Amps and it should work correctly.

    Can someone tell me how you identify which toneprints are installed onto an amp. I've experimented with several compressor ones and can't remember which one I have installed! Can't find any documentation that tells me how to do it and I've gone through all the app (iphone) settings so am I missing something?

      WilliamR The toneprint app will load and store user toneprints on your phone. It will not read what toneprint is currently stored on the amp.

    After many years of having the mk1 BH250, i recently got the mk2 (not sure if these designations are correct, but there are some differences)

    On the newer models i see it says to use the tc electronics 3 button switch to switch between toneprints and mute. on my old one, it only used a one button foot switch to turn on and off the toneprint.

    my question is, can i still use a one button switch in my new bh250 to turn on and off the toneprint (knowing i won't have the functionality to switch between tone prints without the 3 button switch)

    the getting started guide seems to indicate this is the case, but everywhere else references the 3 button switch only.

    I suppose i can test it, but i am worried about damaging the new head if i use a footswitch other than the 3 button tc electronics. On my previous bh250 i used a generic on/off switch to turn toneprint on and off.

    the getting started guide in the manual specifically says:

    Deactivating TonePrint

    To switch off TonePrint, either...

    • Turn the knob of the currently active Toneprint slot fully counterclockwise or
    • use a footswitch connected to the PEDAL jack.

    Thanks in advance for your response! Love the product.

      finky99 also, one other quick question, i assume if i just bought this i don't have to update firmware, correct? Bought last week from Thomann who had just got this batch in. Looks like latest firmware update on the site is from 2017

    Hi guys. I've lost one of the tiny push on caps from the programmablle tone buttons meaning I can't use that sound any more. Anyone have any idea where I might be able to get one that fits. I don't care what colour or length it is but it must havr the right size and shape hole to push on. Thanks, Will.

    Why is there no RH450 or RH750 bass amps for sale, no one has stock?

    Hi Music Tribe,

    Looking for Part# A09-00001-62842 they are small black "push bottons" which help control presets and stored settings. Anyone on here also looking or may have a line on where to order these parts? All service centers were a waste of time.

    Hi TC Team

    I've had my BH550 now for about 2 months, and it's very good amp.

    I love the toneprint feature, but one major issue I've noticed is volume differences between presets - mostly with drive/comp-type effects. I usually have a modulation toneprint in slot B (currently a chorus), and I like a compressor or drive in slot A.

    However, all the drive e compressor (and comp+drive) toneprints are incredibly loud. It's impossible to switch between A and B in a live situation because of this... I have to turn the gain way down for A and then back up when I switch.

    ...the toneprint editor is only for pedals :(

    how to resolve?

      PedroRodrigues Hi Majestic5, thank you for your post, in this case I would suggest performing a firmware update to your unit.

      Updating your TC amp’s firmware requires a computer running Microsoft Windows or OS X with a standard USB interface and a USB cable.

      Preparing the firmware update Download the newest firmware from the link below:

      If a firmware update is available, you will find the following updaters:

      -For Microsoft Windows (these are ZIP archives containing the firmware installer)
      -For OS X (these are disk image files containing the firmware installer).

      Connect your TC amp to your computer using a USB cable.
      Power up the amplifier while pressing and holding the UTIL button on the rear panel.
      After a few seconds, you should see the LED next to the UTIL button turn red

      Launch the firmware updater you have downloaded and follow the on-screen instructions to apply the firmware update.

      When the update is concluded, and you have power cycled you Bass Amp we can them proceed and load a TonePrint to one of the two slots available.
      By default, TonePrint slot 1 contains the TubeDrive TonePrint, and slot 2 contains the famous TC Classic Chorus TonePrint.
      Please follow the link below and download the TonePrint App version 4.5.5 to your computer.

      Once the TonePrint app version 4.5.5 is installed on your computer please connect your computer with your Bass Amp BH550 to allow loading the TonePrint on the Bass Amp.
      Please do not use any type of USB adaptors or USB HUBS, your computer must connect with the BH550 directly.

      Please confirm that the USB cable is in good condition.

      To select a TonePrint slot (1 or 2), set the TonePrint slot switch to the respective slot. The LED of the currently selected TonePrint slot will light up.
      You will hear the TonePrint effect currently stored in this slot, and if you transfer a new TonePrint to your TC bass amp, it will be stored in this slot.
      Use the TonePrint knob for the currently selected TonePrint slot to control the TonePrint in this slot as follows:
      For most modulation effects (Chorus, Flanger, Vibrato and Octaver), the TonePrint knob work as a dry/wet mix control, but for some TonePrints, it could also be the speed of the Vibrato or the depth of the Chorus.
      For Compression and Drive TonePrints, the TonePrint knob usually acts as amount (intensity) control.
      Featured TonePrint artists may have assigned the TonePrint knob to other parameters. Finally, there are some TonePrints that encompass two effects.
      In this case, the TonePrint knob will control one or multiple parameters of one effect, while the parameters of the other effect are static.
      Please note that while your TC bass amp can store two separate TonePrints, only one TonePrint can be active at any time.
      If you do not want to hear or use the TonePrint effect at all, set the TonePrint slot switch to centre position or turn the knob of the currently active TonePrint slot fully counter clockwise.
      Please report back if following the steps provided you where able to resolve the issue described on your BH550. Thank you

        Majestic5 Hi Pedro,
        thanks for your detailed answer!
        I proceeded to reinstall the latest firmware version and now everything works fine.
        Thank you so much for the support you provide!

        a suggestion for improving the toneprint app
        if you could add a slider to adjust the effect's gain when loading the toneprint the management of the various effects would become much more flexible to adapt to the various needs of the songs
        ... and wow!

        Greetings from Italy!

    Early in 2022, I've opened a support ticket CAS-537391-R3X5C4, and I'm now celebrating a 6-month birthday with no response, whatsoever yayyy!!!

    I have a RH750 amp, and my treble knob broke (even inside TC ELECTRONIC expensive bag). The amp didn't fall, or hit anything. I've reported it for the support team. Allegedlly, there were no spare knobs to sell at that moment, so I've waited until now. It has been a long journey, with several emails sent, no response, no support, no cares given.

    Now, there are other knobs about to fall apart aswell, including the Master Knob. There's already a big crack on it, becoming bigger each day. So, sooner than I'd think, I won't be able to use this RH750 amp anymore once and for all <3 Isn't that sweet?

    I'm really done with this disrespectful and outrageous care and support from this company, and I assure I'd never purchase not even a guitar pick from you again.

    Best regards.

    Glauber Costa.

    Hi there, I have some confusion  regarding the rms power of the amp. Can you please let me know the power ratings at 4ohm and 8 ohms so that I can decide to buy a cabinet accordingly.

      PedroRodrigues Hi subhamb88, thank you for you post, please ponder that the information we provided on the output features for the BQ500 are stated on the manual. The BQ500 allows the use of the following cabinet configuration with a minimum load of 4 Ohms. Examples:
      • 2 x 8 Ohm (in parallel)
      • 1 x 4 Ohm
      For the remaining information request please see the manual below. Thank you
      • Aug 22
    • subhamb88
      subhamb88 Still doesn't answer my query. Usually amps deliver full power at 4 ohm load and 50%/60% at 8 ohm. So I want to know what is that exact rating? If I buy a 250w 8ohm cab, it's not ideal if the amp supplies 300W at 8 ohm.

      • TC Electronics BQ500
        PedroRodrigues Hi subhamb88, thank you for your reply, please ponder that as stated on the manual above, the max output power of the BQ500 is 500 watts. This power is distributed equally to the drivers when using more than one cabinet.
        It is also important to take under account that besides the power, consideration must also be given to the total impedance of the speaker system.
        Normally, a speaker cabinet has an impedance of 4,8 or 16 Ω, but when two or more speakers cabinets are used together, the total impedance will change according to the manner in which the cabinets are connected. For details on this matter please see the image below.

      subhamb88 I am aware of of the series and parallel connection of cabinets. I am planning to get the TCE BC208 cabinet. It is a 8ohm cabinet with capacity of 200W rms. Now I read somewhere that the RMS rating of this amp at 8 ohm is 175W which the cab can handle. Am I correct?
      • Aug 23
      • TC Electronics BQ500
        PedroRodrigues Hi subhamb88, please ponder that RMS is the average safe amount of power that can be safely deliver for a long time, nevertheless all the power specifications supplied on our manuals are in Watts and not in Watts RMS. The information on the BC208 manual states that this unit offers 200 Watts as you can see below
        • Aug 23
      • TC Electronics BQ500
        subhamb88 BC208 handles 200W at 8 ohms but does my amp supply less 200W at 8 ohms?

      • TC Electronics BQ500
        PedroRodrigues Hi subhamb88, the important point to take under account is that you should not use a cabinet with less than 4 Ω.

        As long as the impedance value is higher than the rated minimum impedance load on the amplifier you will not have any issues.

        The minimum impedance load is stating what should be the minimum resistance present on the speaker to keep the current draw through the circuit low enough to prevent parts from burning up.

        In the case of the BQ500 operating with one 8 Ω cabinet, I would suggest to setting up two 8Ω speakers to run this amplifier otherwise you would might damage this Amp if you use just one 8Ω 500 watts speaker.
        Please bear in mind that as I have mentioned above, the power will be distributed equally to the drivers when using more than one cabinet.

        TC-Lars Hi subhamb88

        If I may offer an answer.
        The BQ500 will supply a max of 500watt in 4 Ohm. This is not RMS watts, so most likely a peak power measurement, or something along those lines.
        In accordance with Ohm's law the same amp will be able to supply half of that into an 8 Ohm load. So a max of 250watt into the suggested 8 Ohm cabinet.

        It would be completely safe to use an 8 Ohm cabinet with the BQ500 amp.
        The BC208 is rated at 200watt continuous, from the specification above, and can handle in excess of what the BQ500 can supply in peak power it would seem.

        So you should be safe to use the BC208 with the BQ500.

        Best Regards,
