Greetings to you and Congratulations!
If you have built the Cornet 2 successfully, the Clarinet is the same general ballpark. If you had done any of the suggested mods, they are similarly different from 'stock'.
Have a great time. Clarinet is great piece of gear, now that I have lived with mine for about 13 plus months.
Any problems along the way, hollar out!
Best Regards,
DeadFish
