I'd not seen that model Mick.
I use one of these:
as a clip on tuner. Details HERE
. I also have a Fender clip tuner which is OK. The APX700 has a built in tuner, and the tuners built into the Fender Mustangs are easy and accurate (especially easy to use with the 4 button footswitch). For the bass I have a venerable Arion pedal, which is still the best tuner I've owned. On the 'phone I use the Boss TU-3 app.
