I've played one for about three years now, using a Travis style fingerpicking. The Banjitar is a Goldtone name for their 6 string though you can still pick up the odd Gibson 6 string banjo, or spend real money for a Deering 6 string banjo($1300 for the B-6, $1800 for the D-6). In my opinion, after playing them all, the Goldtone 750 is the best of the lot, the 500 next, then the D-6 Deering, the B-6, then the old jazz era Gibsons

Elderly's will get you the Goldtone GT-500 for around $550, while the GT-750 with fancier wood and a bell bronze rim goes for about $750.

They are actually quite a bit of fun to play and if you can finger pick well, you can provide a real counterpoint to even the best 5 string player, since you can go to a bass line he can't get to. In my group we do John's Waltz to the Miller (also known as the Banjo Waltz) using both with excellent results. On the faster tunes (Blackberry Blossom for example) the 6 string can provide full deep chords that acentuate the 5 string higher end. However, it probably does waltzes the best, in a way no 5 string can.

Stumming it is a complete waste of time as the resonance of the bass strings is overpowering alltogether, so picking is your only real option.

Both of the Goldtone models have a magnetic pick-up which is best slid up inside the pot to a point nearest the fingerboard, and used sparingly, with a front dynamic mike to pick up the high end twang. We did a spoof of Johnny Cash and it fit right in. Good Luck!
