This is my, Curt Sheller's main and preferred gigging gear that I use or have used in the past.
The following are my main instruments and related gear:
I have two Ko'olau CS (Contemporary Series) Model Tenor Ukuleles, amazing instruments with a cedar top and rosewood sides and backs. One delivered November 2009 and one from February 2017. These are my main performance ukuleles for everything. Both with a low G. Basically a number one and a backup being groomed and in-training and for live broken string scenarios.
For a details and the nitty-gritty/411 regarding the strings I use checkout this Ask Curt page response: What Ukulele Strings Do You Use?
For amplifiers I use an AER Compact 60 as my main amp for any acoustic instruments (guitar and ukulele) and it works great with the Tele and bass. Backups or if I need a PA include Fishman SA220 PA or one of the Fishman Loudbox series of amplifiers. Typically no effects and for a DI I only use Fire-Eye , L.R. Baggs , Radial Engineering or Fishman .
I really like to keep the gear simple. No endorsements or artist models for me. I like to make my own choices and not be locked in to or be put in a position to recommend a specific brand of gear. The same gear as I have will never make you sound like me and I'll never sound like me by using your gear.
Here are the strings that I typically use on my guitars and ukulele.
Both the Ko'olau and Pono ukuleles have a radius fingerboard which does make a big difference in ease of playing. The Ko'olau and Pono are all strung with a low G. For high G, C tuning I grab my Magic Koa Fluke. Other than Pono I've only found the Godin Multiuke to have a radius fingerboard in a mass produced ukulele.
And with our own music store, ( Funky Fret ) – that is naturally, heavy into ukuleles with a great selection of ukuleles in stock at all times. I'm in a position to play pretty much what I want — but it's the Ko'olau CS Tenor that gets the most action. That and a Pono solid-body are the only performance ukuleles I perform with in concert.
