Sorry... I can't count! I've also got a cheap F340 Yamaha, which I've had for around two years... I got it because I was fed up with people wanting to borrow at singarounds, but it's no big deal with the cheapo!
I bought an under-bridge pickup, and the sound dramatically improved after I fitted it - which was the opposite of what I had expected.
When fitting the transducer I discovered that it would fit perfectly if I carefully gouged the wood out of the bridge until I reached the 'top' of the body... it seems that the bridge insert then made better contact with the body, making the sound 'meatier'...!
